EXS 24 Logic Sampler Users Group

As some of you know, I've lost 3 120-gb external firewire drives over the
last 2 or 3 months.  I thought I did everything right:  used the best drives
and enclosures/chipsets, kept them off the floor, etc.  A couple of people
suggested that maybe they weren't getting enough ventilation/were running
too hot.  This seems likely as I kept them on for long periods of time, and
have been relying 100% on EXS as my sampler for about 3 to 4 months.  This
has got to be the "hidden monster" of working this way.  The price you pay
for all of that convenience!

So--my question to you guys is:  if money is no object, what would the most
stable, reliable, solid-performing solution for storing/streaming EXS
samples be?  Basically, I'm willing to spend more if I can get kick-ass
performance.  I can't afford to have this happen again.  Are there
enclosures specifically designed for maximum heat control?  Should I look at
"boutique" solutions like Glyph?  Should I go with a different format (i.e.
scsi, FW800 etc)?  

Please--help me out here!

Thanks,

Tim
