Background

  • Recently built my own PC. It works! Almost.
  • It's been a while since getting into the guts of these things, so I'm familiar but may be missing something simple.
  • FYI, I don't care about blowing the OS away -- it's brand new and we can go back from scratch as many times as necessary.

Goal / Issue

  • I'd like to use the SSD to take advantage of Intel's Smart Response technology (allows the SSD to act as a cache for HDDs)
  • I would like the SSD cache to act as a cache for my HDDs, which I would like to be in a RAID1 array (so I get the speed from the SSD and the redundancy from the RAID1)
  • However, Windows only sees the drive in device manager (not as a drive), so I'm unsure what to do about that.
  • Related: as far as I know, for this to work, the drives all have to be in a single RAID array (i.e. a RAID0 pairing of the SSD and the RAID1 HDD array).
    • However, when attempting this at the BIOS level, I am told there is not enough space for an array.

Steps so Far

  • Moved the SSD onto the Intel controller (I'd had it on the Marvel 6.0 controller instead of the Intel controller, so the BIOS was only seeing it in a strange way)
  • Updated the BIOS of the motherboard to the latest version
  • Reinstalled Intel's RST (iRST?) software several times, as some forums reported it working after reinstalling 3 times (which does not inspire confidence).
  • Checked Intel storage: it does see the SSD as a physical, non-RAID device. However, it says no space exists if I try to create an array.
  • Checked the BIOS: it does not show up in the boot order, but is an option that can be selected under boot options.
  • Tried the firmware update for that model. Issue: the firmware CD doesn't detect a drive; maybe the Intel storage controller is making it difficult?
  • moved the ssd to the marvel controller. The firmware update cd appeared to hang while searching for drives.
  • swapped out the SATA cable for the manufacturer's and moved back to the intel storage controller.
  • Noticed at this point that in the Intel RST software, a device DOES show up in addition to the RAID set -- only shown as a "60 GB internal disk". Windows doesn't appear to see it as a drive, but it does still show in device manager.
  • Move SSD to port from 0-3 on MOBO and set SATA mode to IDE (after disconnecting RAID1 config) to allow the firmware update to work. Firmware was already at the latest version.

Next Steps

Components involved

  • ASUS P8Z68-V PRO motherboard (Intel Z68 Chipset)
  • Intel i7 2600k Processor
  • 2 x 1TB 7200 RPM HDDs
  • 64 GB Crucial M4 SSD (M4-CT064M4SSD2)

Don't mind the "rebuilding" -- knocked a power cable out at one point; it's doing its job, not an indicator of a bad HDD.

Any thoughts? Thanks in advance for any help!
