    Anyone-

    Do you notice any real speed differences?
    I'm running a duel P3 866 box and have been toying with the idea of going
    software raid for our main share. (four scsi 9.1GB on SCSI 160)

    We also have two OSX servers, one with software raid (we tried the built OS
    raid then went with softraid.com - nice!) and one box with "kind of" sonnet
    hardware raid (four IDE 250GB). For file serving we don't notice any speed
    differences. We didn't do any official testing...just gut feeling.

    I know the software will use the processor for cycles...but file serving
    isn't processor intensive anyway.

    I also thought about going raid on a box we backup to via ftp...just for the
    speed. Hardware or software...worth it?
