Greetings, I recently had the opportunity to purchase a matching WD Raptor ADFD 74GB hard drive and set them up in a RAID-0 array to to host Windows 7. I downloaded the latest Intel Rapid Storage Technology driver and enabled Write-Back Caching, but I don't seem to get the same results some others have posted. Before I setup the Raid-0 array, Windows was installed on a single Seagate Barracuda 500GB and Windows Experience Index gave it a rating of 5.9, but the new Raid-0 array only scores 5.7. I have attached a copy of the HD Tune Pro benchmark results that shows the Raid-0 array is indeed faster than the single Seagate drive, but not by that much. Here is some basic system info: - Intel ICH10R Raid Controller on Gigabyte GA-E45-UD3LR Motherboard. - Raid-0 Stripe set at 32k - Write-Back Caching Enabled - Windows 7 64bit I would sincerely appreciate any advice anyone can offer. All comments welcome.
