Which HDD out of these two?

Western Digital WD3200AAKS 320GB SATAII 7200rpm 16MB Cache - OEM Caviar Blue £30.81 inc. vat

or

Western Digital WD5000AAKS 500GB SATAII 7200RPM 16MB Cache - OEM Caviar Blue £31.35 inc. vat

Would the 320GB drive be more reliable than the 500GB?

have owned both, almost identical performance,

500gb for the win.

If you want to get one that potentially might be more reliable long long term....

either get the slower turning green drives....
or a black... which has the Rock Hard architecture.. or something... with a 5 year warranty.

500gb no question, alot more gb for buck!!!
