Hi John,

I'm glad you found this reference.  I was wondering at what point the
connector might fail due to normal use and wear.  1000 swaps or 3 years
(approx.) is OK for me, but I'll be sure to buy some spares and keep them
around for the eventual rack failure.  

I love these things.  I'm mounting a couple of 120Gig drives in these and
mounting the racks in a USB to IDE enclosure to create what is essentially a
120Gig portable device.  Forget about zip, cd, dvd - 120Gig allows you to
take ANYTHING ANYWHERE.  I may look into a Firewire connection instead of
USB and see if that boosts the speed - but USB is universal and Firewire
still isn't on every machine.  Naturally, this wouldn't be an appropriate
solution where speed is critical, but it would be nice for say demoing Linux
or Hercules without installing anything on a customer machine, and of course
for just transporting huge amounts of data to and from the office.

A word of caution:

for about 1000 swaps - either side. Say, three years, maybe a little less,
with daily swaps.

For your use that's fine.


There are hot-swap caddies too - see www.vipower.com - but hot-swap is  not
an ATA standard, and it does not work with Linux. That said, you can still
shut the system down but not turn off the power to the whole system in order
to swap.

Note that a solution involving a second system, both running drdb, can give
you hot-swap of the whole server.

You could then use _whole_ disk for archives, and swap when you want without
taking down the service at all.
