Another Amiga owner at work picked up one of these and a 2091 from Go Amigo
a couple days ago (they had three 2091s left on Monday afternoon).  They are
the 40S drives, which according to the manual means they have the 64KB cache
on them.  They are also new, not pulled or refurbished.

The report I got was that installation was straightforward (after removing
the plastic faceplate on the drive), and HDToolBox did it's usual great
job of identifying, formatting, and partitioning the drive.  One weird thing
was that HDToolBox had a Q40 drive definition with 9.7 as its (firmware?)
revision number, but when it queried the drive it got something like 6.7.
So I guess it's possible that these drives have been sitting around for
quite a while.  Hopefully they aren't from a production run that had 
reliability problems (were those rumors true?).

These are the results of diskperf on this drive (stock 2000 + 2091 + Q40S)
