Comparitive speed table (disk controllers)

[Karl Denninger]

I promised a posting when we had some good numbers to report if I had
interest expressed; here they are:

Controller	386/ix(1.06)	SCO SV/386	CORETEST (DOS)
----------	------		----------	---------
WD1003-WA2	85KB/sec	100KB/sec	153KB/sec	(1:3)
WD1003-RA2	90KB/sec	105KB/sec	210KB/sec	(1:3)
ACB2372A	-- Unknown --	112KB/sec	670KB/sec	(1:1)
WD1006-V/SR2	235KB/sec	348KB/sec	680KB/sec	(1:1)

(KB = Kilobytes, not bits)

All tests conducted in single-user mode with no daemons active using:
	time dd if=/dev/rhdxxx of=/dev/null bs=32k

Only the wall-clock time was used in the computations, of course.

All measurements were made over at least a 20 Meg partition to reduce error.

I would expect other SV/386 ports to be similar to Interactive (they are
closer brothers than Xenix is).

If we had a reliable installation for 386/ix 2.0 (on the one customer machine
that's using it) we'd have some numbers for that as well....
