I think the TB1 is slightly noisey than the 500g ,thats why i have a f3 500g as my main drive with windows 7 on it ,its in a cage and can,t hear a thing !Is it just the 1TB that are noisy?
I have 2 X 500GB In RAID 0 I can't hear them at all.

I can highly recommend this from personal experience:-
NoiseMagic NoVibes III Hard Drive Cage
Google it! You can get them for 3.5" and 2.5" drives.
