8MB/sec isn't particularly bad for a notebook drive, and I get very
similar numbers on my own 4801-60 w/ Samsung MP0402H drive:
wd0 at pciide0 channel 0 drive 0: <SAMSUNG MP0402H>
wd0: 16-sector PIO, LBA48, 38204MB, 78242976 sectors
wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 2

These boxes weren't designed with screaming disk I/O in mind. They're
meant to be embedded appliances, and this particular model just happens
to have a notebook-drive compatible IDE header.
