What is up with SCSI and XP?

[Kbird]

I cant believe that my performance actually went down. My second machine had an old ultra card and a new Atlas 160 drive. I came across an adaptec 29160 card for cheap and reformatted installed xp and to my amazement my hard drive performance on sisoft was at ata 100 5400 rpm speeds! I've looked around the net and everyone has a different opinion on the problem. Would you guys please help me get my performance back. I've converted to Dynamic disk, produced a little improvement, made sure settings in adaptec bios are correct, and a few XP file system tweaks.



Thanks

there is a huge thread in the storagereview forum about this, the outcome was absolutely nothing can be done about it. Microsoft are working on fixing this problem and it is expected to be in the SP2 patch when in comes out at march/april. Also, don't trust sandra scores but yes there is a problem with SCSI drives on Windows XP and at the moment nothing will help.

I can believe it. I've never seen full performace out of my SCSI drives on MS operating systems. I've been using SCSI drives since 1988 and MS has just never really tried to access them at their full potential.

So what do these SCSI companys test their hard drive on Linux?:) Also what operating systems does Storagereview.com use? I'm :mad: that every review site shows standard SCSI beating the crap out of EIDE drives. How do they come by these results, do they just take the word of the manufacturers?

they probably use Windows 98 or Windows 2000

Someone has apparently found a fix for the SCSI bug, again from StorageReview, here (http://forums.storagereview.net/viewtopic.php?t=5833). I take it that its Winblows's problem :rolleyes:.

^ doesn't help at all for me
also try this candidate release driver for windows xp:
http://www.adaptec.com/worldwide/support/driverdetail.html?sess=no&cat=/Product/ASC-29160&filekey=u160_winxp_drv_rc1.exe

don't expect it to increase your performance either though

in fact i've just realised that i've had enough with this crap SCSI performance, and i'm going to sell my SCSI stuff on ebay and buy a 180GXP when it comes out.
