  • Disabling CPU management

    - by Tiffany Walker
    If I add the following processor.max_cstate=0 to the kernel command line for boot up, does that disable all CPU power management and throttling? I also found: http://www.experts-exchange.com/OS/Linux/Administration/A_3492-Avoiding-CPU-speed-scaling-in-modern-Linux-distributions-Running-CPU-at-full-speed-Tips.html The link talks of Change CPU governor from 'ondemand' to 'performance' for all CPUs/cores and disabling kondemand from kernel.

  • Should I upgrade to Symantec Endpoint Protection? [closed]

    - by Alex C.
    I'm the IT manager at an animal shelter in Upstate New York. We have a Windows network with about 50 desktops running Windows XP Pro. We used to use CA eTrust Antivirus, but that product didn't work too well (too many infections got through). About six months ago, we switched to using Symantec Antivirus Corporate Edition ver. 10.1.8.8000. If anything, the Symantec product is even worse. The last six weeks in particular have been very bad -- we've had about seven or eight PCs get hit with those malware infections that masquerade as antivirus software. In most of those cases, Symantec didn't even flag the malware at all. So... what gives with the Symantec Antivirus? As far as I can tell, it's installed correctly and downloading updated definitions nightly. I can upgrade to Symantec Endpoint Protection for $220 (we get non-profit pricing), but I don't want to do it if it's not going to be significantly better. Any advice? Should I switch to something else entirely? Thanks!

  • Running mod_php and suPHP same time

    - by BHare
    I recently went from Debian Lenny with 5.2.x and was able to use mod_php for any php files that were not located in /home/ and suPHP for all the php files that were located in /home/. I did this because I needed a default php.ini (given me all features of php) for my websites in /var/www/ and I didn't want to have to change the owner of all the .php files from root. I also had a default php.ini for all the /home/ php files without dangerous features. This was I had setup: <IfModule mod_suphp.c> <Directory /home/> AddType application/x-httpd-php .php .php3 .php4 .php5 suPHP_AddHandler application/x-httpd-php suPHP_Engine on suPHP_ConfigPath /home/shared/ </Directory> </IfModule> This was working perfect, but recently I upgraded to PHP to 5.3.5 from dotdeb (Lenny has no official php 5.3) . This had weird issues on lenny such as not display errors correctly and little tid bits. So I decided to upgrade from lenny to squeeze. Uninstalled php (along with it came suphp) and reinstalled with the new source. I now have 5.3.3-7 with Debian Squeeze but I cannot get mod_php and suPHP to run at the same time anymore. mod_php will always work and there are no errors in apache2 or suphp logs. If I disabled mod_php then suPHP will work. Is there thing I am doing wrong?

  • IIS7 Compression CSS files only compressed when dynamic compression is enabled

    - by Paul
    If anyone can help it would be appreciated. I would like to enable compression for static files within IIS7 (for the sake of simplicity I'll just refer to static css files for the time being). The problem I'm getting is that css files are only compressed when both dynamic and static compression is enabled in IIS for the website. What I really want to achieve is css compression (static file) whilst leaving the dynamic (aspx) pages as uncompressed for the time being (to avoid unnecessary CPU load). I am puzzled as to why just leaving 'static compression' enabled causes css files to be returned uncompressed. My applicationHost.config file has not be altered and looks like this: <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files"> <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" /> <staticTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/javascript" enabled="true" /> <add mimeType="*/*" enabled="false" /> </staticTypes> <dynamicTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="*/*" enabled="false" /> </dynamicTypes> </httpCompression> The server-wide compression setting within IIS is set to 'Dynamic Disabled' and 'Static Enabled' from the Server Features Compression page. The web-site compression setting (Server Sites MyWebsite Features Compression) is where I am enabling and disabling dynamic compression as detailed above. Any help would be really help me get unstuck on this. Thanks

  • Windows 7 disk backup and clone for deployment to multiple systems

    - by gregmac
    I'm in the process of deploying some new PCs (there's only 8), all identical hardware. What I'd like to do is install Windows 7 (64bit), join to domain etc, install a bunch of other software, and then clone that drive to multiple other machines. I'd also like to be able to use it as a backup image, so the machine can be restored back to that image at some future date. I understand this involves at least sysprep, but I am confused after reading some tutorials that talk about using Windows Automated Installation Kit, or hacks with the registry and custom-build batch files. This process seems overly complex to me: I did something similar 10+ years ago, and and don't remember it being this bad. Surely things have improved in a decade? There's also some products that involve having network servers running deployment software, network boot, etc etc.. this is way more than I want to set up. My systems are all identical hardware. Is there a simplified way to clone PCs? Preferably (since I'm a lazy developer, and not an IT admin) I'd like to find some off-the-shelf product that I can run after I get the machine setup, that will spit out a bootable DVD I can run on all the other systems, which will boot up, ask for a computer name, join it to the domain, and that's it. Does such as product exist?

  • SQL Server 2005 Express: upgrading to SP3 in mixed-mode installations

    - by Jeroen Pluimers
    I'm having trouble upgrading SQL Server 2005 Express SP1 to SP3. The SP1 install uses mixed mode authentication (so there is an sa password). This is the message I get: TITLE: Microsoft SQL Server Setup ------------------------------ None of the selected features can be installed or upgraded. Setup cannot proceed since no effective change is being made to the machine. To continue, click Back and then select features to install. To exit SQL Server Setup, click Cancel. For help, click: http://go.microsoft.com/fwlink?LinkID=20476&ProdName=Microsoft+SQL+Server&ProdVer=9.00.4035.00&EvtSrc=setup.rll&EvtID=SQLSetup90&EvtType=28108 ------------------------------ BUTTONS: OK ------------------------------ The link then tells me To continue you must provide a strong sa password. I tried some searching, and found something about BPAClient.dll, but this batch-file does not fix it: mkdir "%ProgramFiles%\Microsoft SQL Server\90\Setup Bootstrap\BPA\BPAClient" copy "%ProgramFiles%\Microsoft SQL Server\90\Setup Bootstrap\BPA\bin\BPAClient.dll" "%ProgramFiles%\Microsoft SQL Server\90\Setup Bootstrap\BPA\BPAClient\" So I think the clue is the strong in the link above. Am I on the right track? Where do I find more information on the strongness of an sa password? --jeroen (who will adjust the question when he has dug further)

  • Installing SATA dvd burner on machine with no spare SATA ports/connectors

    - by Faheem Mitha
    Greetings. I have the following motherboard Tyan Thunder K8WE S2895A2NRF Motherboard - extended ATX - nForce Pro 2200/2050 - Socket 940 - UDMA133, Serial ATA-300 (RAID) - 2 x Gigabit Ethernet - FireWire - 6-1 channel audio This is part of a computer that was assembled in the winter of 2006/2007. The user manual says the following with regard to SATA Integrated SATAII Generation 1 Controllers (from NForce Professional 2200) Two integrated dual port SATA II controllers Four SATA connectors support up to four drives 3 Gb/s per direction per channel NvRAID v2.0 support Supports RAID 0, 1, 0+1 and JBOD. I just purchased a SATA DVD burner. Here is the page for the product http://www.amazon.ca/gp/product/B002QGDWLK/ The problem I am facing is that I already have 4 SATA drives installed. I don't want to remove any of them. However, I want the DVD burner above installed as well. The person I am consulting with here (Bombay, India) tells me that my four available SATA ports are filled, and that my only option is to install a SATA card into the one free PCI slot on the motherboard. However, he says that with this setup I will not be able to boot from the DVD drive. Are these statements correct, and what are my other options if any? Even it the statements in the last para are true, I suppose I could use one of the motherboard connectors/ports there are currently being used with the hard drives with the DVD drive, and use the "add-on" connector with one of the hard drives. Not all the 4 hard drives need to be bootable. BTW, despite having read through http://en.wikipedia.org/wiki/Serial_ATA#Cables.2C_connectors.2C_and_ports I am fuzzy on the differences between connectors, cables and ports. Thanks in advance.

  • Finding a backup and synchronization solution

    - by Andrea Zilio
    I'm having difficulties to find a backup and synchronization solution with the following characteristics: Cross-platform: Windows, Linux, Mac Offsite backup (so Internet Backup) Data deduplication Transfer only new/modified bits of modified files Secure: Data encrypted before leaving computer Maintain multiple versions of files (even deleted files) Folder synchronization integrated with backup and across multiple computers connected to the internet (not necessarily in the same LAN) I think that the Folder Sync feature needs a better explanation. The use case is this: you have a desktop pc and a laptop. The desktop pc contains a folder with some files and this folder is part of the backup (so it was selected to be backed up). The laptop does not contain that folder or that files at all. Then you're abroad with your laptop and you need that folder. So you want to be able to open the backup program, select that folder from the backup and download it in your laptop mantaining it synchronized with the backed up version. When you then come back home and switch on your desktop pc you want the folder we're talking about to be updated in the desktop PC. Does anyone knows any service with all these features? I've only found SpiderOak to support all the features I've mentioned but I'm not completely satisfied by the time taken to complete a backup. Sometimes it seems to hang for minutes with no reasons at all and folder synchronization occurs only after all files are backed up (instead folder sync should have a separated queue independent from other backup operations and synchronization should occurs frequently... for example every 5 minutes or less, independently from the frequency of normal backup operations)

  • LAN network (switch?)

    - by guywhoneedsahand
    I am working on setting up the network for a small LAN party (less than 16 people). Most of them do not have wireless cards in their rigs, so I need to set up some way for everyone to a) play LAN games and b) access the internet. The LAN party will probably take place in my basement, where I have enough space. However, the basement is not wired up with the router which is actually on the floor above. I make a cantenna a while back that can boost the wireless performance of my computer significantly. How can I use this to provide internet and LAN to guests? My hope was that I could use a switch like this http://www.newegg.com/Product/Product.aspx?Item=N82E16833181166 for the LAN - but how can I give people access to the internet? Is there such thing as a network extender / 16-port switch? Obviously, the internet performance doesn't need to be super stellar, because the games will be using LAN - so I am looking to provide some usable internet for web browsing, and very high speed LAN for games. Thanks!

  • GNOME 2 + Compiz equivalent?

    - by virtualeyes
    Running Fedora 14 and realize I need to either change distros or find an alternative to GNOME 3 in Fedora 17. Based on what I have read to-date, XFCE and KDE are the go-to WMs if I want to avoid GNOME 3. I tried KDE 4 and I wasn't impressed; I like the simplicity of GNOME 2 with Compiz and Emerald. Can't stay on Fedora 14 forever, however, so...where to turn? Basically looking for these features in my desktop environment: GNOME Do or equivalent Snap to grid/Window tiling A must-have, the ability to hot key focused window to a monitor grid region is a huge productivity win. Zoom window to cursor In a multi-monitor setup sometimes it's nice to, say, GNOME Do terminal in one monitor and then hot key the opened window to the other monitor just by zipping the mouse cursor anywhere on target monitor (followed by, of course, snap-to-grid hotkey, all without a single mouse click) Polarization At night white background hurts the eyes, so I prefer to hot key polarize to black. Multi-monitor support I'm partial to Fedora given that I've worked with CentOS for years and have little experience with any other Linux distro; however, if the difference between Fedora and Arch, Mint, etc. is fairly subtle, I'll make the leap, just need a distro & desktop environment that allows me to be productive with keyboard hot keys and provides the above basic features. Any suggestions?

  • Internal Use Chat/Desktop Platform

    - by Malnizzle
    I did some looking, but I didn't see a SF question directly related to this. I need to find a platform for internal/LAN use only for chat and desktop sharing. We got a lot people having to get up and walk over to another person's office for simple items, and we could save a lot of time collectivity if we had a solution where we had a client app similar to gchat or AIM, where one could right click a name and request a desktop sharing session (to or from). This wouldn't be for product presentation or long training sessions, and wouldn't need more than 2 people in the session. We use GoToMeeting for this. I've looked at TeamViewer, and they got the features I want (plus a lot more features that wouldn't help) and seem more geared to large enterprise support, and it is not exactly cheap. Also looked at OCS some as well, but it seems heavy for what I am trying to do. I don't need anything relating to phone usage. If the general opinion says otherwise, I could talked back into OCS if I am wrong about weight of the product. We use GoToAssist for remote support of clients (which I am a fan of), and I don't it fits here, correct me if I am wrong. All the workstations are XP/7. Thanks!

  • What causes Windows Media Player on Windows 8 to not play the entire library?

    - by somequixotic
    Behavior 1: Verify that the WMP playlist is clear of all songs. Turn on the "Shuffle" and "Repeat" features. Double-click on a music track in the Library. Click the "Next" button (double right angle brackets). A random song from any track in the Library is randomly chosen and played. When observing the Playlist (clicking the "Play" tab), the entire contents of the Library appears in the Playlist. Behavior 2: Verify that the WMP playlist is clear of all songs. Turn on the "Shuffle" and "Repeat" features. Double-click on a music track in the Library. Click the "Next" button (double right angle brackets). The button visually depresses like it has registered the click, but nothing happens. Absolutely nothing. Moreover, the "Previous" button is grayed out. When observing the Playlist, only the one song that was double-clicked appears in the Playlist. What causes Behavior 2? I cannot correlate any specific action I've taken with Behavior 2, and Behavior 1 has been the case as long as I can remember, all the way back to Windows XP. Even earlier during my usage of Windows 8, I recall Behavior 1 working correctly. But suddenly, inexplicably, without changing any settings in WMP, Behavior 2 kicked in, and persists after reboots. I've tried sfc /scannow in an administrator prompt. All system files are in order. I've downloaded all Windows Updates and driver updates. I've attempted to alter WMP options and playback settings to no avail. So... what is causing Behavior 2? Is this an intended, valid behavior, or is something malfunctioning? How would I know what that "something" is? How would I go about fixing it without just reinstalling Windows 8 fresh?

  • How to get an ARM CPU clock speed in Linux?

    - by MiKy
    I have an ARM-based embedded machine based on S3C2416 board. According to the specifications I have available there should be a 533 MHz ARM9 (ARM926EJ-S according to /proc/cpuinfo), however the software running on it "feels" slow, compared to the same software on my Android phone with a 528MHz ARM CPU. /proc/cpuinfo tells me that BogoMIPS is 266.24. I know that I should not trust BogoMIPS regarding performance ("Bogo" = bogus), however I would like to get a measurement on the actual CPU speed. On x86, I could use the rdtsc instruction to get the time stamp counter, wait a second (sleep(1)), read the counter again to get an approximation on the CPU speed, and according to my experience, this value was close enough to the real CPU speed. How can I find the actual CPU speed of given ARM processor? Update I found this simple Pi calculator, which I compiled both for my Android phone and the ARM board. The results are as follows: S3C2416 # cat /proc/cpuinfo Processor : ARM926EJ-S rev 5 (v5l) BogoMIPS : 266.24 Features : swp half fastmult edsp java ... #./pi_arm 10000 Calculation of PI using FFT and AGM, ver.

  • Load Testing a Security/Gateway Appliance

    - by Joel Coel
    In a couple weeks I will load testing a security/gateway appliance. We're a small residential college, and that "residential" means the traffic moving through the appliance is a bit like the Wild West. We have everything from Facebook to World of Warcraft, BitTorrent to Netflix, or Halo to YouTube... basically anything you might find in the home of a high-school or college aged person. Somewhere in there some real academic work gets done as well. We rely on our current appliance for traffic shaping, antivirus, malware filtering, intrusion detection on our servers, logging and abuse reporting, and even some content filtering. All this puts a decent load when we have students around, and I'm concerned about the ability of the new candidate to keep up. On paper it should handle things, but I'm worried. Prior experience is that vendors greatly over-report what an appliance can handle. The product also includes a licensed session limit, and I'm also worried that just a few misbehaving students could unwittingly bring us to that limit and cause service disruptions. I need to know this will work for our campus in order to commit to it. Going a performance level higher in that product takes the pricing way out of line with what we expect and have done in the past. What I need is a good way to load test this guy. My problem is that our current level of summer traffic is less than one percent of what it will be when students come back just six weeks from now. Any ideas on how to really stress this thing and see what it can do, in a way that will give me some clear ideas o. How that will scale for our campus? For the curious, I'm looking at a Watchguard 515, but it could be anything. If I were evaluating a competitor, I'd ask the same question.

  • Is Windows Server 2008R2 NAP solution for NAC (endpoint security) valuable enough to be worth the hassles?

    - by Warren P
    I'm learning about Windows Server 2008 R2's NAP features. I understand what network access control (NAC) is and what role NAP plays in that, but I would like to know what limitations and problems it has, that people wish they knew before they rolled it out. Secondly, I'd like to know if anyone has had success rolling it out in a mid-size (multi-city corporate network with around 15 servers, 200 desktops) environment with most (99%) Windows XP SP3 and newer Windows clients (Vista, and Win7). Did it work with your anti-virus? (I'm guessing NAP works well with the big name anti-virus products, but we're using Trend micro.). Let's assume that the servers are all Windows Server 2008 R2. Our VPNs are cisco stuff, and have their own NAC features. Has NAP actually benefitted your organization, and was it wise to roll it out, or is it yet another in the long list of things that Windows Server 2008 R2 does, but that if you do move your servers up to it, you're probably not going to want to use. In what particular ways might the built-in NAP solution be the best one, and in what particular ways might no solution at all (the status quo pre-NAP) or a third-party endpoint security or NAC solution be considered a better fit? I found an article where a panel of security experts in 2007 say NAC is maybe "not worth it". Are things better now in 2010 with Win Server 2008 R2?

  • Good PC-based video conference control tools?

    - by Jeremy Wadhams
    I'm looking to improve the user experience in our video conference rooms, by simplifying the things users do all the time (setting up a call, muting and unmuting, panning and zooming between a few room-appropriate presets) and totally taking away the functions that we don't use or that are more likely to ruin the experience (changing the brightness of the TV, using the VNC presenter mode). The rooms each have Tandberg Edge or MXP video units, I'm not looking at PC-based solutions like Skype or iChat. The classic way to do this would be to plunk down huge money for an AMX or Crestron panel. This does have some advantages, and I am considering that approach, but in my initial investigation, that looks expensive, inflexible, and proprietary. On the other hand, the Tandberg video units I'm looking to control are very thorough XML API (PDF), so some of the integration magic that Crestron and AMX consider to be a value add, I could reproduce at mashup speeds. Anyone aware of an Open Source or Commercial product that takes advantage of the readily available web APIs, some simple touch screen PCs, and builds a product that is more like skinning an AJAX web app, and ideally more cost effective than the proprietary panels?

  • Nexus functionality is limited after installation

    - by Dmitriy Sukharev
    I have a CentOS based server with Sonatype Nexus 2.0.4-1 installed. The issue is that there are no standard "Artifact Search", "Advanced Search", "Browse Index", "Refresh Index" Nexus features, as well as Artifact Information tab after selection of any artifact (only Maven Information tab). I tried to Google, but was amazed that there're no information about this issue. Actually it looks like all actions I've done are: wget http://www.sonatype.org/downloads/nexus-2.0.4-1-bundle.tar.gz tar -xvf nexus-2.0.4-1-bundle.tar.gz cp -r nexus-2.0.4-1 sonatype-work /opt/ ln -s /opt/nexus-2.0.4-1/* /opt/nexus ln /opt/nexus/bin/nexus /etc/init.d/ chmod 755 /etc/init.d/nexus vim /etc/init.d/nexus NEXUS_HOME=“/opt/nexus” RUN_AS_USER=“nexus” useradd -s /sbin/nologin -d /var/lib/nexus nexus chown -R nexus /opt/nexus/ chown -R nexus /opt/nexus-2.0.4-1/ sudo -u nexus cp /opt/nexus/conf/examples/proxy-https/jetty.xml /opt/nexus/conf/ To force Nexus be available through HTTPS I went to Administration - Server - Application Server Settings as admin and changed Base URL to https:// external IP/nexus and set Force Base URL to true. Any ideas how to get missed Nexus features?

  • What are some alternatives to word processing with Markdown?

    - by Hassan
    I've used MS Word-style editors for a long time, but I never got used to how unintuitive and cumbersome they are. I'm not talking specifically about MS Word, but also other editors that seem to mimic Word, like OpenOffice, NeoOffice, etc. I've found myself preferring to write in Markdown (much like on this site). I've found a few good Markdown editors, and I like using them a lot more than using Word-style editors. Here is what they generally look like: As you can see, it works much differently than a Word-style editor. This is a generally cleaner way of writing, since formatting is done right in the text, and is extremely simple to use (no highlighting some text, then clicking a button in some menu you have to find). Although editing text this way is great, I've realized that the syntax can only be used for very specific needs (bullets, numbered lists, headings and sub-headings, bold, italic, and some other common ones). However, many features are missing. Here are some features that would be nice in a word processor: Tables. Indenting paragraphs. Good image support (you can link to images, but not add them, since Markdown is just text). More simple to use than Word and its cronies. Cross-platform. Some of these can be fixed with in-line HTML, but nobody wants to do that. It seems Markdown was designed for editing text on the internet. Is there a similar setup that works better for desktop word processors?

  • Blue screen issue

    I received several BSOD's that are recorded in the following logs: Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7601.2.1.0.256.48 Locale ID: 3081 Additional information about the problem: BCCode: 50 BCP1: FFFFF95FF8150C10 BCP2: 0000000000000008 BCP3: FFFFF95FF8150C10 BCP4: 0000000000000005 OS Version: 6_1_7601 Service Pack: 1_0 Product: 256_1 Files that help describe the problem: C:\Windows\Minidump\040412-20030-01.dmp C:\Users\Jack\AppData\Local\Temp\WER-33025-0.sysdata.xml ~~~~~ Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7601.2.1.0.256.48 Locale ID: 3081 Additional information about the problem: BCCode: 1e BCP1: 0000000000000000 BCP2: 0000000000000000 BCP3: 0000000000000000 BCP4: 0000000000000000 OS Version: 6_1_7601 Service Pack: 1_0 Product: 256_1 Files that help describe the problem: C:\Windows\Minidump\040412-32729-01.dmp C:\Users\Jack\AppData\Local\Temp\WER-64319-0.sysdata.xml It seems to occur at random. I have gone 2 months without a BSOD, then I have gone a week with 10+ without changing what I am doing. This is my system: Windows 7 Professional 64-bit Gigabyte GA-890GPA-UD3H AMD Phenom II x6 1090T Processor 3.2GHz 8GB Ram(4X 2GB) Radeon HD 7850 2TB HDD Thermaltake 500W PSU I'm not sure about what the BSOD says, it just counts to 100 by 5's then restarts the computer. It happens fast and I have tried to get a picture before but to no avail.

  • Is there a small business router that shows bandwidth usage graphs in the admin panel?

    - by Robert Drake
    I support a large number of public libraries that are having their networks upgraded in response to a grant application. These libraries are generally home to between 6-15 computers and have little or no tech services either onsite or contracted remotely. In order to justify current and future purchases, a number of the libraries have requested routers that can provide bandwidth usage graphs that they can show to their managing boards. Is there a small business router that displays traffic graphs in the router administration web interface? The router needs to suppport DHCP and basic firewalling. No other features are required. Further, the reports just need to show overall trends. It is not necessary to show traffic by IP, by protocol/application, or by time of day. They just need an overall week to week, month to month, trend line. I'm familiar with MRTG/PRTG/tools that collect SNMP data from the router, but the libraries don't have the expertise for the configuration. I've considered installing the tomato firmware on some cheap home/home office routers, but if there's a commercial product that can be purchased that would be significantly simpler. Also the library boards would be much more likely to approve the purchase of a commercial product over a 'hacked' one. Any assistance would be appreciated.

  • Are SATA II and SATA 3.0 Gbps compatible?

    - by Johnny Maelstrom
    I am trying to check that if I buy a new internal HDD it will work in the NAS I am buying. Currently I'm confused about naming schemes and once that is resolved whether there is compatibility. I will gladly author this question to be more general if there is not already an article helping with the confusion of SATA naming and standards. I see similar, but not identical questions and will accept this as a duplicate if thought as such. The specifications on the eCommerce site for the NAS says, "Controller Interface Type Serial ATA-150", the product home page for the manufacturer says, "Compatible with SATA and SATA II HDD". The specifications on the eCommerce site for the hard drives say, "Interface Type Serial ATA-300", the product home page for the manufacturer says, "Interface SATA 3.0 Gbps" Wikipedia says many things about different naming conventions, the closest being, "SATA II 3.0 Gbit/s, which was colloquially referred to as "SATA 3G" [bps] or "SATA 300" [MB/s] since 1.5 Gbit/s SATA I and 1.5 Gbit/s SATA II were referred to as both "SATA 1.5G" [b/s] or "SATA 150" [MB/s]). Therefore, they will operate with negligible differences between them." Are SATA II and SATA 3.0 Gbps the same? I feel I'm tantalisingly close to getting a definitive answer here before I purchase, but really want to clear up these naming schemes.
