well heres the thing, im running out of space soon so im thinkng of buying either: 1 400gb seagate hdd $400 OR 2 200gb on raid $360 well im tryin to save money so i dnot mind the raid. my rig before this upgrade is found on my sig below. PSU is a thermaltake TWV 480watts. does it matter which one i pick with regards to power? i know one of the draw backs would be more noise since i got another hdd now. please give me your views as its kindly appreciated. oh ps just to remind i have a raid-o 36g raptor and also a 200gb seagate already.
