WTF is wrong with this picture? This is an IBM UltraStar 15,000RPM Ultra160 SCSI drive. It's running as the only drive on an Adaptec 19160, latest drivers, WinXP Pro, all patches/drivers/service packs totally up to date.

Brand new install, no applications installed yet, clean:

What do you think could be wrong? Bad cable? Bad terminator?

    One.. They made 15k Ultrastars for years and the one s from a few years back top out at 20,000 or so. But teh bottom end you see in your atto??? Thats teh notrious microsuxs fix for ya....next microsux fixed a bug in their ntfs filesystem where they were not supprting the "write_thru_flag" whcih is supposed to tell the controller and disk to bypass any cache on the controller and disk itself Its supposed to just impact writes but some of my controllers show it in ATTo on reads also. bad controller bios/firmware is my guess. But the good news and bad news is in real life only two programs have ever been found using the flag... ATTO... and (grin) Windows explorer doing file copies. They want to be really "safe" on those copies. (long sigh...) they also fubared win2k in sp3 the same way. win2k3 has a work around. And tehy have a patch for win2k if you are running sp4 or later.

    For now you have two choices. I have a weird driver you can install that basicaly "masks" the call to any scsi disk. or... if you don't mind the downside you can convert it to dynamic disk. They "fixed" ntfs but not their own frigging own goofy dynamic disk subsystem. So if you want to see how good it should perform real quick just convert to dynamic. I bet the bottom end jumps to few thousand anyway. I got scsi drives for sale prime... from 18gb to 147gb... I only deal in the fast ones but my prices are really pretty good. This isa u320 10k IV maxtor. Its not running good I been jacking with the firmware and this was a bad time to bench. It usually gets about 73,000 on atto. But look at how outrageos the reads on the low end are. Its like at 50,000 after three rows. A 36 gb would hit you for under $150. Actually for you it would be less as your a bud...

    Also.. The Elite 1600 you bought from me doesnt support the stupid write thru flag anyway. They just thumbed their noses at microsoft.
