I currently have 1x20gb WD Protege and 1x20gb Fireball on the same channel, and to speed things up a bit plan to buy either :-

"Western Digital Cavier SE 80Gb 7200rpm 8mb Cache Hard Drive OEM @ £65.36"

OR

"Maxtor Diamondmax Plus 9 80Gb 7200rpm 8mb Cache ATA133 Hard Drive OEM @ £64.92"

I'm not sure which one, both are almost exact same price apart from a few pence and they both seem to be of similar spec. Do you think it's worth me upgrading for the performance increase I would gain? (spec in sig, as usual)
