I've heard the 80 MB CMS drives contain a 64 KB cache that drops the
average access time from 26 ms down to 18 ms, which is good for a drive
of this size.  The CMS drivers were recently updated to perform "blind"
reads and writes, which is how the SCSI port is purportedly saturated.
This drive definitely *seems* faster than the 40 MB Apple drive.
Apple's HD Backup (System 4.1 and 4.2) work fine; I've only used the
verify function of Apple's First Aid and it seemed to work also.  I've
had my Pro80ii for almost 2 mos. now and had zero problems with it.
The CMS drives are significantly less expensive than any other
manufacturers' I've found.  (Try M.A.C. in Berkeley where the Pro80i
internal sells for $1180, or if you're an Apple Certified Developer
you can buy the same drive for $999 directly from CMS [Tustin, CA]).
