Yep, SCSI performance dropped from 2K to XP. Big bug. Dunno if it's fixed in SP1. Anyone done any benchmarks?
 
Gonna check out the thread at storagereview and see if it has.

guys how fast is SCSI supposed to be?
I have 2 SCSi HDD's (9.1 GB each) hooked up to my AIC-7895 Dual ULTRA SCSI onboard.
In nero when i tell it to test my drive speeds this is what i get:
 
IDE HDD (Partitioned)
C:\ 12,172 Kb/s
F:\ 14,912kb/s
 
IBM ULTRA SCSI master (partitioned)
E:\ 11,648 KB/s (BOOT HDD)
H:\ 8,842 KB/s
 
IBM ULTRA SCSI Slave
D:\ 3,443 Kb/s
G:\5,900 KB/s
 
I think SCSI should be faster than IDE?
i was not dong anything while this test was taking place:
DK440LX
Dual PII~300Mhz
512Mb RAM
Windows XP
 
Yes yes, i Am getting a new PC soon and moving up to modern technology...

if i look at my sys event viewer i see a warning at boot
 
driver turned off write behind caching for this drive
 
i dont think it messes with raw transfer speeds just slows down overall performance

well, u were right, after i disabled Sophos 1 of my HDD's were much faster, they got to 15mb/s but the other one stayed lower than 5mb/s @ about 3...,
And what is the average speed for ULTRA SCSI?
