    Well, If you are dealing with very large video files, a larger block size is called for.

    If you are dealing with lots of little files, smaller.
    If it's a mixup, go somewhere in the middle.

    Here's a good resource on the subject:

    I'm planning on ditching my internal RAID array for 2 single larger drives unless maybe I can get ahold of an Apple RAID card. Why? Software RAID has its downside. Namely: the increase in Disk transfer rate is offset by CPU cycles needed to manage the RAID array.

    With drives like the Caviar Black I feel less need to RAID them together.

    Have Fun,

    yeah, you're right on the CPU thing, but the issue was that my work flow was being choked by hard drive writes being slow. the quad core rarely gets maxed, so I figured I had cycles to spare.
