I've got a couple of 533 MHz machines with the SuperMicro PIIIDME board
and
here is the output from hdparm -t. There is a cheetah drive
and a SCSI-3 controller, which, although not technically relevant, do
show
the potential of the chipset. Note that, for example, with the same
SCSI
card and disks, I get 13 MB/sec with a 566 MHz alpha. This is the first
time
I've found an Intel chip to have faster I/O than an alpha.
[root@scylla /root]# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 64 MB in 2.92 seconds =21.92 MB/sec
