Speaking of apples and oranges..
The "current" and "cheap" ATA drives are all EIDE now.
The "current" and "cheap" SCSI drives are all SCSI2 now.

False. EIDE "overhead" has not changed since ATA was invented.
The throughput has gotten much better, though.
Quote:>territory. Max drives under XIDE is _STILL_ 2, one master one slave.
Wrong. No max, but in practice the limit is two master, two slave.

A long time ago, except for "CMD" interfaces.

Wrong again. Most drives, ATA *and* SCSI, peak at around 5.5MB/sec from
the heads these days.
