Subject: RE: External HDD / USB question
Parallel port HDs also work. I've got an external case from www.h45.com and
dropped in a spare laptop HD. No problems at all, except that during
transfers
to the HD, the machine under Windows does become very, very sluggish as the
CPU
will be completely tied up working on the transfer. This won't happen under
USB because only the p.port requires constant CPU administration during
transfers.
16bit PCMCIA is also big CPU hog
However, I chose p.port because I wanted DOS compatibility, something no USB
HD
can give you because there's no DOS USB support at all. This way, I can
transfer files off a system in case of an emergency, or if I'm using Ghost
to
backup my system under DOS.
As I mentioned before PCMCIA work in DOS
As for PCMCIA HDs, you've got three choices.
1) SCSI PCMCIA adapter to external SCSI HD - fastest.
(there's also firewire, but ignore this for today because drives are very
expensive, and no drive yet exceeds the bandwidth of SCSI, which is far
cheaper)
CardBus Firewire($100)->Firewire to 36pin IDE ($89)->External case
2) IDE PCMCIA adapter to external IDE HD - slightly slower than SCSI, but
far
cheaper for the HDs.
Bottleneck for both is 16bit - quite slow though
