the ST-32550N is the 2 gigger barracuda. got one here at home, and works great.
we have heavily used servers using Barracudas, and a couple of Hawks, both
2 and 4 gig models. we have had no apparent heating problems. I do have some
problems with certain Connor 2-Gig drives... You can fry an egg on them...
I'm afraid to put one in a system of any importance... Although the one I have
in my home box here [the CPF2107S], has yet to have any problems with this
model [not quite as good as the barracuda on the i/o speeds, though].
But then again, the servers I mention are in a temperature/humidity controlled
environment; other cases and environments could cause overheating of ANY drive.
