How to increase the speed between two external hard drives on my laptop?
- by Roman
Hello,
I own Sony Vaio Z laptop with two external USB ports. It's quite new and has USB 2.0 support. I'm using Vista x64 on it.
I also have two external usb hard drives, Iomega 500GB and WD for 1TB. Every hard drive has USB 2.0 support.
I connect two devices to my laptop and trying to copy date from one hard drive to another. But it takes a lot of time! The speed is about 15 Megabytes per second. I have to wait toooooo long to copy all the information from one hard drive to another.
When I try to copy information from my internal (SSD) hard drive, it works fine for both external drives. The speed is very high and it shows me something about 100 Megabytes per second. It makes me feel that USB 2.0 is OK on both drives.
But when I'm trying to copy from one external drive to another external, I still get very low speed.
I checked out Device Manager and here is the settings I have:
(sorry, can't upload image because of my rating, check this url: http://picbite.com/image/122073daljo/ )
I think it's because two of my external drives use the same USB 2.0 controller.
Is there any way to make it work faster? Is it possible to move one of my USB ports to other USB 2.0 controller?
Or is there any software which can help me to automate copying all the files thru my internal drive? I have only about 3 gigabytes free space on internal drive and it's quite difficult to move manually every file from one hard drive to internal and then again to another internal.
