RAID block size for video

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,
