DEC DSP3105, Fujitsu 2694S, HP C2247, IBM 0663 model E12, Maxtor MXT1240S,
Micropolis 2112, and Seagate ST11200N. The Fujitsu is just being released

DEC was said to be very fast but tended to be "noisy" and ran "hot", perhaps
too hot to be used internally. The warranty on DEC drives vary by distributor.
HP was said to be a reliable drive but also expensive. HP gives it
a 5 year warranty.
Seagate gives a 5 year warranty - little was said about the drive. A Seagate
spec sheet that listed the rotational speed as 4500 RPM was accidentally
released. The proper speed is 5400 RPM and current spec sheets have been
updated to reflect this.
Micropolis gives a 5 year warranty - it also tended to be the lowest priced.
Beta versions of the drive were said to have compatibility problems but
production versions are supposed to have no problems.
IBM gives a 5 year warranty - was said to be a quiet reliable drive.
Maxtor is supposed to be fast and looks like the fastest in term of maximum
sustained transfer rate [6300 RPM]. Not yet available so compatibility and
pricing are not yet known.
Fujitsu has been selling its drive overseas for a while. Fujitsu America
is just releasing the drive in the U.S. No one who owned one commented.
