Has anyone used either a 168Mbyte Fuji drive (model 2284)
or a 160 Mbyte CDC drive (model 9715) with or without an
Emulex SC21V unibus controller? We want to buy a medium
sized Winnie and are looking for experience with reliability.
I gather that the Fuji is shipping in limited quantities,
and has a somewhat higher MTBF. The CDC supposedly is more
readily available and more companies will service it. Then
of course there's the "buy American" argument. Prices are
approximately $5500-$6K each (discounted). Any suggestions?
Any others we should be looking at?

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...
