    I wouldn't say the raptors are worth it personally.

    If you wan't good availability get 4 drives and use a hot-spare maybe ?

    How much is it going to get hammerd by the users? I too would question the use of raptors. The seek time is nice, but would be put to better use with large database.

    Didn't consider IDE as it's replacing a SCSI system where a failed drive is no longer available. The raptors are more expensive than IDE but less so than SCSI. Don't want them coming to me and saying it's not as fast as it used to be.

    Aye, but SCSI covers a range of technolgies dating back to 1985! IE a lot of it is very slow!

    What was the model of the SCSI drive that failed?

    By all means go SATA, but not neccecarily Raptors. Maybe somthing with a 16Mb cache and NCQ. Also, try to get drives from different batches if possible.

    Drives are 36GB SCSI 80pin - MAXTOR 5A300J0. Ultra 160 caddies, 320s didn't work too good. Running off an Adeptec 2100.

    To be honest the existing system has been a bit of a disaster.. drives regularly failing over a 4/5 year period. Covered by a replacement warranty, but a pain none the less.

    So now I'm really looking forward to ripping it all out and putting in a shiney new setup as above.

    Was just wondering if the Drive/Card/Board compatabilty was ok.

    Think I will go with the hot spare, Demon. Do I need caddies to hot swap?

    The Western Digital SD series are aimed at server-Raid array use, they have a MBTF of 5 years as opposed to 3 on most other consumer drives.

    Does this look ok?
    I used to own one of those. Solid as a rock! Never used raid though.

    agree..

    if you're going raid stick with either SCSI or the SATA raptors's

    You need your drives to be fully reliable which SCSI and Raptor's practically guarantee..
