Thanks everyone for the suggestions. I will look into different case
options. The case I currently use is a 2ft tower that holds five to six
drives but doesn't provide ventilation necessary for the seagate drives,
which seems to run hotter.

I agree I have found the Seagate drives to be much more reliable than quantum e
speccialy.
However you need to cool them well. Often a problem since most case manufacturer
s don't seem to understand this or care.
I use and reccomend cases from siliconrax. (www.siliconrax.com) Most of their c
ases pull All of air across the hard drives via 3 large fans.
One interesting thing is that I have been getting Barracuda drives that seem to
be rebuilt but are being sold as new.
Recently I have started to use their cheeta drives and they are quite nice but
generate A LOT of heat.
