Hi Guys!
I need some advise from those who has done any RAID (0,1,5..). My main problem is that i need more space in my computer. I had considered making a raid 0 between 2x2TB WD or Seagete (5400/5900 ones), but I realised their were 2 slow and they used to have some problems (i read newegg's opinions)

So finally i figured maybe I could do a raid with 4 x HD103SJ (so nice bench's ive seen) but do you think it is TOO RISKY? I just want to store some HD films and intall games. Of course its not very important content but i dont want to loose anything (since raid 0 has that problem, 1 disk fails, bye bye) or should i go RAID 5 and loose some storage/performance?
Thanks !

P.S
