thanks Nethawk,
Well yesterday I had a think what to do with the HDD's. Looking at SDD's drives, they seem okay but with a couple of drawbacks: size (enough just for windows.. maybe a odd program nothing else), slower preformance when 60% filled (still fast but seems old) and the limited amount of writes.
After-which I looked at HDD's and amazed at what you could get for your money. I decided to get a WD black 2TB for main drive, then get another 2TB for a data drive (this one not as fast). Then with 3 x 500gb place them with my old motherboard (3 of the same could be RAID'ed) then the 2 x 320gb give them to dad (he has 1 x 320gb already, so he could RAID all 3 together). So this would give me 4TB, winky 1.5TB and dad 0.9TB. My system looked like a mess with 5 drives in it, 2 looks much neater too! hopefully ill be able to get them tomorrow!
The PS3 sucks for typing: ive had to re-write this message atleast twice! if you hold the shift key and backspace (sometimes happen when holding shift then pressing a letter) it deletes the whole message without a undo feature! The PC is so much better at web-browsing!
