Are iomega hdds any good?
My only experience is with an older model DHD080-U bought in early
2005. It ran hot because the enclosure was small, not very
ventilated, and lacked a fan. I've since drilled lots of holes in its
enclosures to improve the cooling.
If you buy an external HD or an enclosure, look for either a fan
(better cooling) or a big enclosure (better cooling) with lots of
venting (better cooling) and the ability for vertical mounting (better
cooling). Did I mention that you want good cooling? I wouldn't
accept a fanless drive or enclosure unless it could be mounted
vertically because that alone can provide significant cooling and even
helps internal HDs inside desktop machines (2-3C cooler body, 10-20C
cooler power chips). Watch out for small or loose drive stands for
vertical mounting because you don't want something that will let the
drive tip over or shake if the table is bumped. If necessary, make
your own stable stand out of something like wood.
It may be cheaper for you build your own external HD by buying an
internal IDE HD and an enclosure separately. Here's a very good thread
about enclosures:

Be sure to get something that's UL approved (backwards "R" followed by
a "U", looks sort of like "9U"), especially if the enclosure has an
internal power supply because a LOT of those are obviously not UL
approved and even look kind of dangerous (shock, fire hazard). Bytecc
is one brand that is UL approved, made by Welland, while Neo is one
that is not. Almost all external powr supplies are UL approved, but in
any case always verify the approval number through the online
certification database at
www.ul.com.
Be skeptical of any enclosure that's claimed to be cooled through
heatsinking because that may not work well, even if it consists of
thick aluminum pieces that screw to the sides of the HD (the only
places where effective heatsinks will work) and have gooey material to
improve conduction. And sometimes the heatsinking is only trivial, as
with my Buffalo USB HD, whose enclosure is made of a thin steel chassis
("Unique heatsink chassis keeps internal parts cool") having very
little contact area with the HD. Also steel conducts heat roughly 10x
worse than aluminum does.
