Gee, Todd Carpenter thinks his drive is slow, with (using the 8192 byte buffer):

read @ 327,680 bytes/second, and write @ 257,846 bytes/second  ??

Sheesh!

Peruse the April 1989 UNIX Review (Vol. 7, No. 4), page 98, for disk perfs
of some "other" systems (these are sequential read tests of the first 2MB of
an 8MB file using an 8192 byte buffer):

Apple Mac IIx     109K bytes/sec (SCSI)
Compaq 386/25MHz  154K bytes/sec
Sun 3/50          232K bytes/sec (SCSI)
Sun 3/160         237K bytes/sec (SCSI)
IBM RT            267K bytes/sec
Sun 3/260         620K bytes/sec
MIPS M/120-5      656K bytes/sec (SCSI)
Sun 4/260         794K bytes/sec
