Well, I'm not quite sure we are talking about the the same drive,
but I have been running on a Fujitsu m2322K 168.55mb 8inch drive
for a few months now connected to a Xylogics controller (SMD on
Multibus), and I'd have to praise the drive. The unit gets a fair
amount of abuse (I work on disk software for the OS group), and
it has stood up to it very well, no problems whatsoever. Position
time is average 20 milliseconds and the raw data rate is
1.2mb/second which translates to just about 1.0mb/second actual
user data for us.
Geometry of the drive is a fairly standard one: 10 heads, 823
cylinders, and a tracksize of 20,480 bytes. This gives you 32
sectors per track easy, and we actually are squeezing 34 sectors
onto a track.
Almost forgot, it has an automatic head lock which is very
convenient.
Anyway, they claim a MTBF of 10,000 power-on hours, and MTTR of
30 minutes. Given this particular drive, and all the other Fuji
drives I've used, I'd tend to believe them...
