Is this with "Write-back cache" Enabled in IRST panel?

In Device manager > disk drivers > your Array > Properties > Policies check "Turn off Windows write-cache buffer flushing on the device" in win 7 improves performance a bit.

No, Write-back cache is off in the 2 cases. Only HDD cache are Enable.
