    raid

    Hello,
    I am looking in to raid for my new computer
    its eiether raid or a 36gb raptor for my system drive and a 160gb drive for my data.

    for raid i would want the folowing
    High Performance with Data Security (RAID-1) with 2 Identical Hard Drives
    this may sound stupid i but i need it answered.
    can you still partition the drives as normal?
    i want 4 partitions.
    system,data,music,images

    of course if i used a raptor as my system drive i would have one partition on the raptor and three partitions on my other drive.
    thanks in advance

    thanks for the replys.
    i will most likely get raid rather than the raptor then.

    you want data security that suggests to me that your data is resonably important.

    make sure you backup as raid 0 increases the risk of data loss and corruption. You will also find your machine harder to recover from issues rather than with one real physical disk due to fake raid drivers on your motherboard requiring windows....but windows is borked......but you need the drivers....but windows is borked chicken and egg style.
    It is Inevitable.....

    well infact i want RAID-1 which is raid data security and speed.
    i didnt just want mirror because it wouldnt be any faster than one drive.
    so thats why im gonna get RAID-1 which has both.
    well i dont like the idea of raid 0 since if one drives goes then the data is lost.
    if i where to get raid 0 i would just store windows on it.
    and then get a second harddrive for all my data and images of the raid 0 array.

    but RAID-1 has both speed and redundency doesnt it?
    does raid or a raptor really make much difference compaired to a normal hard drive?

    Its offers redundancy yes, but the only performance gain you get is reading from the disk, this wouldn't kick in on the majority of situations though (it works in an entirely different way to the gain you get from RAID 0 when reading / writing). You get a slight hit when writing to the drive, but its quite small.
    RAID1 is certainly not aimed at performance, and any RAID1 solution you use probably won't be optimised in that way.

    Hi agent,
    thanks for explaining.
    would it be better to get raid 0 for the OS and get a data drive for my data and images of my OS raid?
    thanks in advance

    Don't think that RAID1 offers any aditional performance (in some cases it performs worse than a single drive), if you get extra read performance consider yourself lucky, but it's not part of RAID1 specification, write performance will almost be the same however.

    You get a reading performance increase when the card / drivers / OS / whatever supports split seeks. This allows one drive to be reading something different to the other. It also helps if for some reason one drive can get the data faster than the other.

    Part of the RAID specification? As far as I know, there is no single body that makes RAID specifications? One manufactures implementation can be entirely different to another (hence why you can't just swap to a different controller).

    The writing hit is small, but it does happen.

    What OS?

    If linux, go with software raid. It's fast, flexible & well established as part of the kernel,
    meaning it's easier to recover from failures, as you aren't reliant on a manufacturer specific format for which support might no longer exist. In this case you can partition physical drives & put those into raid configurations, rather than just whole drives.

    If you're considerintg hardware raid I don't think you can generally raid partitions, but there's no problem creating a raid & then partitioning it, which is I think what you want anyway.

    As to the raid configuration take a look at wikipedia. If you really want performance & security consider raid 10 (a minimum of 4 drives required).

    OTOH You might find raid 0 is good enough along with a regular backup schedule which you should be doing anyway.

    Regarding whether to use raid 0 for OS, programs, data or some combination of these, I'm not sure. In fact I'd be interested in comments on this one myself.

    In my case the stuff I want to benefit from raid 0 is video & image processing. I was thinking of installing OS & programs to one drive & storing my data on a raid 0 setup - any comments anyone?

    but no data security.

    bottom line %99 of the home users will not see any benifit from using raid 1, less so on crappy on board home user raid controllers.

    Those that will get any performane benifits will not be asking what to do in a forum as they will know how to tune their machines and applications to get the best out of it.

    Just put your OS on one partition and your data on another and backup on a regular basis. If you have real concerns over data protection you can mirror the whole disk/partition that way you'll have OS stability as well as data.
    It is Inevitable.....
