I'm using mine with an Adaptec 4070 controller,er,efter 2 weeks of debugging
(it ended up being a faulty cable) I finally had a hard disk.  It's been
two months with no troubles.  The drive is a fujitsu 2242 (40M) which I got in
Silicon Valley for ~$250.

Here's my diskperf numbers.  If anyone sees anything wrong with them, it
could be that I did something wrong.  (Question, can the Stardrive handle
an interleave of 1?)

		Fujutsu

I quit there...  hope this is useful.
