Mark,
Do you know, or have any experience, with reliability of the brushless vs.
belt driven? My bet would be on the brushless motor (the belt being the weak
point) but you never know.
I haven't been in the retrocomputing game long enough to get a feel for that yet, and
8" drives were already on the way out when I started getting original experience back
in the day. My gut feeling is that the direct drives ought to have more reliable spindle
drive systems and less RPM flutter. There are also other considerations, though; for
example, on the TM848, it's not as easy to get access to the heads for Q-tip cleaning
as it is on some of the older, bulkier drives, so an older drive might be more practical
for imaging lots of questionable old disks that are likely to shed oxide.
