Raid0 question

  1. I want to turn my gaming rig into a striped raid array. I know the 2 drive's have to be the same. My question is the same true for the drive's cache. I have 2 seagate 500gb 7200.11 drives but one has a 16mb cache and the other a 32mb cache. Can I still use these 2 drives together or will the cache size really make a difference?
    Thanks for any help!

    hardware cache in the HDs is invisible to the OS and its drivers, so NO they do not need to be the same.

    HOWEVER, I would strongly advise you to search the site for all RAID comments;
    raid-0 will be a disaster upon the very first disk error and force you into a full system
    recovery. ARE YOU READY FOR THAT???

    Thank you jobeard for the reply. I am still researching the pros and cons of doing this. I do welcome the info which does allow that option.

    Thanks again,

    getting the option, or better said, making that choice and implementing it on a specific
    machine is the trivial part.

    it's the consequences that frequently get over looked and then when disaster strikes,
    we hear "Oh my, how do I recover my ..."

    suggest you get some good backup software and practice creating backups and more
    importantly, performing restores in at least two modes:
    1. restoring a simple directory to a given date
    2. learning how to recover the whole boot disk
      (hint: normal backup will not recover an HD which will not boot as it doesn't
      capture the MBR)
    For case (2), you need something like Ghost or Acronis True Image 11

    I have been using ghost for years to make my own system restore disks. Once I get a new install done with all essential programs installed I ghost it to dvd's.

    Very good suggestion that other's would do well to heed!
    It has saved my bacon many times.

    In your opinion would you set up a raid array to get alittle more performance out of the pc or is it a case of extra work for little gain?

    At least you asked :) IMO, it's the latter -- even Microsoft does not recommend Raid-0
    for the Boot disk
    !

    Thanks again jobeard. I do believe I will pass on the raid setup.

    It just seems when I built this rig I expected more performance! I went from an old socket a amd 2700+ with 1gb ddr 3200 and an agp video geforce 7300 512mb ddr2 with no sata connections on mobo to this setup. There was a performance gain but again not what I thought it would be.

    Just trying to get the most bang for my buck!

    Again, thanks.

    you're welcome -- my objective on this subject is to keep users SAFE and not let them
    make brash assumptions based upon techno-bable terms that require special 'care & keeping' for the average home user.

    (gee, maybe that's a bit transparent; teeheehee ).
