My drives have been on the //e as long as I can remember. They seem to be
quite hateful of the high speed banging though that the IIgs gives it.
Although I have to admit I love the sound they make while doing normal
seeks. Hearing them an octave higher is oddly satisfying.

Where on earth are you finding them at that price? I only have a total of 3
working 5.25" drives left. The two Apple 5.25" disks that belong to my //e
and the Atlas 5.25" half height.
