Just built a new PC. RAID 5 with 3 x WD Caviar Black 640GB Harddrives. Two-Way CrossfireX, Radeon 4850. Phenom II X4 3.2 GHz. Asus M4A79T Deluxe.
Anyhow, thought I'd try out Windows 7 on my new comp. It took some work, but I got the RAID drivers on a USB and was able to install. However, when I look in the Windows Device Manager, it displays "AMD 2+1 Disk RAID5 SCSI Disk Device". Why does it call it a SCSI device? I spent money and time so I could have a sick fast SATA 3.0 RAID 5 setup, and Windows is calling it a SCSI disk device? Did I do something wrong? Should this be of concern? Is there anyway to test and confirm that my transfer speed are indeed 3GBps to my Sata RAID?
Perfectly normal for it to be displayed as a SCSI device.
You can download and run HD Tune, but you are not going to get ANYWHERE near 3gbs transfer rate. Probably more like 220-260mb/s is in the ball park.
