I'm trying to decide what to go with for primary storage on my 286 - options are CF-IDE or SCSI
SCSI adapter is an AHA-1542B with the old BIOS that only goes up to 1GB, system BIOS only goes up to 504MB on IDE.
Not terribly worried about space concerns on a 286, but I would like to go for maximum performance. CF will obviously be the best with respect to seek time, but I know they are notoriously slow for writes, and not super great for small file reads either.
CF would have the advantage of being a full 16-bit path from drive to processor, whereas SCSI is going to be limited to 8-bit HBA-Drive transfers.
Considering the limitations of a 12MHz 286, which do you guys think would provide best overall disk speed - a CF card or a 5400+RPM SCSI disk with 1MB+ cache?
