We replaced the 20Mb drive in our PS/2 30-286 with a 42Mb drive from Procom
Technology (200 McCormick, Costa Mesa, CA 92626 714/549-9449). Coretest 2.91
values are:

Data transfer rate: 700 KB/sec
Average seek time : 30.7 ms
Track-track seek  :  1.7 ms
Performance index :  5.96

The drive uses 2,7 RLL and has a 32Kb RAM for caching and track buffering.
The list price is $895 (we paid less). They also have a 101Mb version for
$1895 list. No slot is required and installation takes less than 30 min
(really). We put the original 20Mb drive into a PS/2 30 (8086).

We have been very happy with this drive. The usual disclaimers apply.
