Again, that's a "fact" without anything to back it. The RAID setups
I've worked have been far more concerned with speed of access to data
and use of logically large disks for things like databases. Aside from
which, the above still doesn't make sense: why is it safer to send
your data to a raid controller only to have it sent back to be
checksummed/replicated/whatever before beeing written down to disk?
Seems like you're increasing the complexity of the write process,
and more to the point increases the risk of putting inconsistent data
on the disk.
I'm just looking for some backup (ha!) on these facts, I guess. Not
doubting that you don't have it or questioning your expertise or
anything.
Cheers,
Waider.
