I too, am using a SCSI+.
I'm using an A1200 with a 127-meg, 2.5-inch, Seagate ST9145a drive.
Without the SCSI+, I get a speed 199Kps using SYSINFO on the SPEED test, but if
use SYSINFO's read SCSI option on a partition before reading the SPEED, I get
899Kps instead. Using the SCSI+, SYSINFO gives a reading of 790Kps.
A major difference appears in the amount of CPU available for other tasks when
accessing the hard drive. Without the SCSI+, I have 80% of the CPU free, but
access the HD with the SCSI+ active the CPU changes to 0% free.
Other have reported that their A1200's (with othe model HD's) have a 800Kps
rate.
Apparently, some IDE drives are more standard than others.
Since the A1200 IDE interface & the SCSI+ are CPU driven, a faster CPU could
affect the speed, and free up more CPU time for other tasks.
