Currently my large archive of files are spread over many drives (and also safely archived on others) and I'll be moving a bunch of them to a RAID setup when I get the New Mac Pro. Haven't decided on the chassis yet, but will probably go with the empty Promise unit. I'l be buying four 2TB drives but I'm not sure which will be my best option. I usually buy WD Cavalier Black, does anyone have any recommendations for good and reliable drives, preferably with bang for the buck - though safe storage of my data is the priority over saving money, I mostly deal with audio, but also some video. Would I be OK with Cavalier Black or should I look into Enterprise Options (or is that overkill) ? (I'm investing in a 6TB 2Big for TimeMachine, which I'll run as RAID 1). With thanks for any input.
