Nigel, you might be just the man to ask (I hope Ryan does not mind).
I’ve got five hard drive bays. I want to put C:\ as a stand alone 7200 RPM 1TB hdd and back up externally. Then I want to put D:\ as four 7200RPM 1.5TB hdd’s in RAID 10. I would put two 1.5TB drives together for a 3.0GB RAID 0 array, and then that array gets backed up to another identical array in RAID 1 (making it RAID 10). Backups are external to a Drobo (4.06GB capacity) and also USB 2.0.
I would store all stock footage and media on D:\, and also use it for output and rendering (D:\Temp). Is that fast enough? I like the idea of the redundancy. (As I see it, my other option is to put all four drives in one massive RAID 0 array, but then there is no redundancy.) Can you or Steve please comment?
