So trying to work out what External RAID to get with my new nMP. PROMISE Pegasus2 R4 Diskless 4Bay ($699/£426.19 + say £100 for shipping to UK = £540) with four of these. HGST 4TB DeskStar 7K4000 SATA 6Gb/s 7200RPM 64MB 3.5" Hard Drive (£145x4 = £580) would these be the best drives? So in Total £1,120. What speed would you expect to get with 4x4TB in the R4? With what ever the fastest RAID is (without worrying loosing data) I've read RAID 0 or RAID 5 Or LaCie 5big thunderbolt 10TB is £820 20TB is £1,500 I basically need at least 10TB for all my animation work. Sorry I'm not very clued up on all this RAID stuff even after reading about it. Any advise would be useful!
