That is a very common feature, and most certaily not limited to 3ware!

I have Areca, Adaptec, and LSI Logic RAID cards that can all do the same.

Linux software raid (md) can also check an array for problems, Debian offers to run a cronjob
every month to do that, if you install mdadm. Coupled with SMART autotests you're pretty safe.

If you want to be pretty safe, you'll need to test every *day*, not once a month.  I know this
from experience.

This sounds like a useful media scrubbing feature.  However, sector checksumming seems like it
requires filesystem changes, and I've only seen that proposed in btrfs, which is in early
development stages.
