Hello,
I recently bought four SSD drives and hooked them up in RAID 0 configuration with an Adaptec card. I was hoping to leverage my full 4GB of RAM by using Windows 7, but was disappointed to find out that while sequential write didn't differ much, sequential read performance I benchmarked (~410 mb/s) was less than half than on 32-bit Windows XP Pro SP3 (~830 mb/s). Thinking it was a Windows 7 issue, at first I tried the latest drivers, and after that Windows XP Pro 64-bit edition. However, the same poor performance remained, even with upgrading the intel SSD to the improved 8820 firmware. Listed below are the details of my hard and bench. Has anyone else had similiar problems? Why would using a 64-bit OS be an issue in hard disk performance?
Thank you for the help!
ssd: intel X25-M Mainstream SATA SSD SSDSA2MH080G1 x 4 drives
raid card: adaptec raid 5405
M/B: asus P5Q PRO
