    Hi,

    I’m a beginner setting up a PC system for HD video editing with Vegas
    7

    With some useful basic guidance about the PC spec needed for this job
    which was generously supplied by two of the local gurus here during
    earlier posts,
    I’ve now bought the main parts of my new system – see below [1]
    (maybe I went over the top, but the required spec for HD editing is
    reasonably well met, I hope)

    I’m now considering hard drive configuration and wanted to ask which
    forms of RAID (if any) are preferred by you wise and experienced video
    people….

    RAID 0 (with some careful backing up on an external or additional
    drive) is one option.
    RAID 5, with some extra outlay (or perhaps choosing 3 disks of 350gig
    rather than two of 500gig) also seems a possibility.

    But perhaps you feel the possible risks and extra financial outlay for
    a RAID type configuration is not really worth it for the speed (or
    extra backup,in some configs) you may get?

    Obviously this affects which hard drives I’ll buy, and whether I go
    for some kind of RAID card

    Thanks very much if you can kindly help out with any of your views or
    experience on this….


    With regards
    Jeremiah

    P.S Also, any recommendations regarding a suitable video card for this
    system would be gratefully received


    [1] the system so far…

    Asus P5E3 Deluxe motherboard

    Intel Core 2 QUAD Q9450

    4 gig of RAM FSB 1333

    SATA hard drives yet to be chosen.

    The monster downside to RAID 0 is that a failure of *either* of 2 drives
    takes you down for the count. In this day and age, a drive failure must be
    planned for.
    The incremental cost of 500 GB drives over 350 GB drives is such that I
    don't know why anybody would bother with 350 GB drives.

    The wonderful upside of RAID 5 is that there are a lot of reasonably-priced
    system boards that support 4-drive RAID 5 for negligible incremental cost.
    Any of the 4 drives can fail, and your system keeps ticking and your data is
    safe.

    If you want peak performance out of your hard drives, you are pretty well
    committed to on-board controllers because of the bottlenecks inherent in the
    PCI bus.

    IME drive performance isn't the current hard limit to rendering speed, CPU
    power is.

    Surely any half organised editor/post house will still have the
    original source material available until the job has been signed off,
    if not for sometime after, so one already has a back-up should the
    RAID go down. The time for rebuilding a RAID after a HDD failure is
    probably not much different to re 'capturing' from the original
    source. Admittedly if one has to hire in the pay-out device the
    considerations will be different, in those cases something like RAID 5
    might be worth the extra cost/resources.

    Raid 5 is the way to go - just remember to buy a spare drive at the time
    of purchase because when-and-if you ever need that drive it must match
    the other drives, and frankly, a matching drive may not be for sale when
    you DO need it!

    Thanks all of you for your responses. I'm going for RAID 5 with three
    500gig drives. I'm gratified to see how cheap they've got now, so a
    setup like this now seems a natural option instead of a big cash
    layout for something extravagant. I just sourced some SATA 500gig
    drives at about the same unit price as I paid for an 80gig drive a
    couple of years ago (it may not even have been that long)! And I
    recall being very happy with getting an 80gig for that price at the
    time : )
