I'm looking for a small capacity drive for my new build ie <160gb and looking for sugestions. I've read some posts on the sammy F1's but they seem to have been problamatic, also as i'm on a tight budget and the fact that my NAS holds all my important stuff should I just go for something like a Western WD740 Raptor? would these work ok in RAID 1? or the WD1600AAJS?
