Just for reference, Maxtor and CDC offer nice big drives at around $2000.
The Maxtor SCSI/ESDI drive at 380MB, 16ms access time, is a really nice
drive. The CDC Wren-IV 327MB SCSI is also around $2000, 16ms access time,
but last I heard this sucker was back ordered a good long time. (Don't
let the numbers fool you; they both format to about 300MB.) These are for
naked drives - to use on the ST, you also need to buy a power supply, some
cables, and a SCSI controller card. (Adaptec or Berkeley Micro Systems
seem to be the preferred names.) A case is also nice to put around it, and
you should find an ST-to-SCSI host adapter board. (As far as I can tell,
ICD and Supra's products are almost identical in this area. Although the
ICD disk driver does write verification, and the Supra docs don't mention
whether it does or not. Both have battery backed-up clocks on the adaptor
board. Seems like a waste to me. I kinda wish they sold a version of the
card that didn't have the clock - why pay for something I won't use? I
get a clock with my RAM upgrades... Plus, the ICD and Supra clocks take
up a logical unit number on the SCSI bus. Ah well...)
