What type of hard drives are these and what should I choose?

Discussion in 'Amateur Video Production' started by Dilbert D. Danglewiggy, Dec 13, 2005.

  1. Hello,

    I am purchasing a top of the line DELL XPS 600 that I intend to use
    for editing home movies. I have several different options with regard
    to hard drives. I have listed some of the options below:

    * 500GB Serial ATA II Hard Drive (7200RPM)


    * 160GB Performance RAID 0 (2 x 80GB 10K SATA2 HDDs)

    * 160GB Data Security RAID 1 (2 x 160GB SATA HDDs w/ Native Command
    Queuing)

    Should I get a cheaper ATA drive or one of the Raid SATA hard drives?
    What's the difference between Raid 0 and Raid 1? How about SATA1 and
    SATA2? I plan on buying two hard drives. How should I configure them?

    I don't buy computers very often, but when I do I like to get the
    best. If there are any suggestions in regards to other computer
    manufactures I should consider I would appreciate that information as
    well.

    Thanks in advance!

  3. You can read about what the different RAID classes are in
    several places online.

    IMHO, you don't need RAID of any kind. A couple of large,
    independent SATA drives would be the most useful for
    video editing. At least that has been my experience. But I
    have only edited a few hundred hours of video.

    I can't help you with the SATA drives, but I wanted to
    mention that it is desirable to have a drive for your
    video that is separate form the boot drive that
    contains your software and operating system.

    Raid 0 ties 2 or more drives together in such a way
    that they appear to be one large drive that is roughly
    the size of all of the drives combined, and substantially
    faster because files are spread across the drives.
    Good big fast drive.
    Bad I any of the drives fail ,
    all of your data is permanently gone. (2 x 160 = 320)

    Raid 1 ties pairs of drives together in a redundant manner.
    That is to say that the data on one of the drives in each pair
    is exactly like the data on the other drive in that pair.

    Good any single drive can fail and your data is still
    available and the array can be rebuilt.

    Bad each pair of drives only holds as much data a
    one of the drives in the pair, and it will be a little slower
    than the individual drives would be on their own. (2 x 160 = 160)

    It is preferable that all of the drives in an array be of the same type and
    size.
