FYA - The drive is a HB HD on 'long-term loan' from someone...its not
the best in the world, but its good enough for me!


Tested on a stock IIGS with two cards:  A GSX and a REV C SCSI card.

The HD is formatted at 1:4 or 1:5 interleave.  That may change soon.

Under 5.0.2:       8MHz      Off | Under 5.0.3:       8MHz      Off
                                 |
Linear Read        5.19    10.15 | LR                 5.16     9.98
                                 |
Random Read       25.36    31.42 | RR                24.81    29.20
                                 |
OS Overhead        1.48     3.47 | OSOH                .72     1.55

Not great, not too shabby...the OS OH is cut in half...looks like I
should reformat my HD for a better interleave...then again...when I get
a CVT I'll have to anyway.
