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...
