Hi all, I've got mac pro (2 x 2.66 GHz Dual-Core Intel Xeon, 5GB RAM, 250GB SATA 3Gb/s drive) and FCS 2. While currently looking at 3 x 400 (or 2 (or 3) x 500)GB hard drives and to RAID them to store the footage (about 9 hours of Beta SP 10 bit... needs about 1TB, I believe) that I'm going to work with, now I'm sort of confused by several questions. I'll appreciate it if any of these can be answered. 1. Due to redundancy issue, I'm thinking of RAID 0 and 1 all three (or two) of drives. But, does that mean I need to RAID 1 them to external hard drive(s)? 2. When you choose hard drives, do you look at seek time for video editing? Since WD Raptor drives are out of the question (too small and too expensive), would 8 (or up to 8.9) ms seek time be good enough? Even under RAID? 3. Does video editing require faster write time? If it does, does it get affected by RAID 1 (write twice... right?) at all? 4. Or do you consider counting cents per GB when you choose hard drives? Prices may vary from vendor to vendor, but isn't it a smart buy if you choose, for instance, 28 cents/GB (Maxtor) over 35 cents/GB (Seagate) on same 500GB? But does it really matter when the hard drives are RAIDed anyway? 5. Due to spindle, is it true that 3 x 320GB would run faster than 3 x 500GB under RAID? Or the difference is too small to ignore regardless of seek/write time? I apologize in advance if any of those questions doesn't make sense. A newbie to Mac to begin with, I've never done RAID myself, which worries me a bit. Once again, thanks for any insights.
