    RAID with XP Pro?

    To protect my library, I am thinking of getting 2 750Gb SATA drives and mirroring them to give a net capacity of 750Gb.

    Anyone with experience of doing this with XP Pro? I'm not so keen on a consumer RAID card for reliability.

    And will an XP Pro mirrored set be OK for an upgrade to Vista?

    Mirroring will _not_ protect your files from deletion, corruption or
    anything besides disk failure. RAID is interesting if slimserver is a
    timely critical application for you, where you can't afford an
    interruption of a few hours. Otherwise it's waste of money and unneeded
    complexity.

    Go with a single internal disk and an external disk for manual backups.

    It's much safer to get a multi- bay drive enclosure: http://www.cooldrives.com/usbenclosures.html
    Buy your drives in pairs. One "working" and one "backup" drive.
    Slide in the backup drive and use: http://www.allwaysync.com/
    Keep backup drive in safe or off site.

    well raid for mirroring does have some benefit if you like the idea of an immediate backup without the need to do a manual or scheduled backup. this helps when one of two drives goes bad.

    if you combine mirroring with a third drive for backup, then I think you cover it all.

    I am thinking of getting the western digital my book world edition II.

    But what if you get a virus? What if you delete something you wish you hadn't? Sorry, too bad, the changes get written to the second drive immediately.

    RAID 1 will help you in the event of disc failure and nothing else. It is not a backup. You'd be much better advised to use the second disc in an external backup before considering RAID 1.

    I am using RAID10 (stripe + mirror) on my HP workstation server. I use 4x250G high speed SATA drives. HP workstations have Intel RAID built in.
    RAID 10 has both speed and redundancy advantages. It will continue working if one drive goes bad. Obviously it makes sense to have a spare drive handy in case that happens.
    The main trick is to have a floppy drive to load the Intel RAID driver when you load WinXP.

    You can also use Software RAID5 on XP:

    For "backup" you can use SyncToy from Microsoft and keep the files sync'ed up on an external USB drive.

    RAID with XP Pro?

    I agree that if you can only do one or the other, backups make more sense,
    assuming the backups do proper versioning.

    But for me, I do both. I take the backups for peace of mind, but if I have
    a drive failure, I like being able to be back up and running quickly. I've
    had one drive failure in my 8 years or so with this RAID setup, and the
    rapidity with which I was back up and running was well worth it for me.

    Certainly, if you can do both, that's great. But backups first, then RAID.

    BTW something to consider: will your RAID card still be available if it were to die? This happened to me recently - I had a RAID 0 (*cough, cough*) set on an Intel ICH5R southbridge RAID controller. Then the motherboard died. Where can you get a board with an Intel ICH5R RAID controller these days? Nowhere. The new Intel RAID controllers are incompatible with the data structure. The data on the drives was irretrievable.

    So I'll have to restore from backup. Still haven't fully recovered yet.

    A true hardware RAID controller, while expensive, will probably be available for quite some time though.

    This is a fairly senseless approach to configuring music storage, unless, like Michael stated, you can't afford to have your music server down for even a minute. Again, RAID redundancy does not offer a "backup" of -any- sort, not even an "imediate backup".

    RAID with XP Pro?

    It may not be immediate, but in my case, I was back online within an hour or
    so, not counting the time it took to purchase and install a new drive (which
    would be the same for RAID or for a restore). Backing up to my external
    drive takes many hours (for the first backup -- the subsequent incrementals
    are faster, of course), and I'm sure the restore would take a comparable
    amount of time.

    For me, it's not senseless. The extra cost is not that great (I've been
    using the same < $100 RAID card for the entire 8 years, and the extra drive
    was probably around $100), and I've already experienced the benefits.
