I don't know why performance did not double for you or anyone else. Maybe
it's due to hardware issues. But I can tell you for a fact that my stripe
setup on two different machines did factually double. I'm not trying to be
difficult, I'm just giving my opinion based on my experience. Maybe you
didnot use a hardware based raid?

Why did my hard disk performance double? Sorry Ken but you are wrong on
the
performance issue.


That's your opinion. I disagree. I've tried RAID0 here and I saw no
discernable performance improvement at all. I know many others who
report the same thing.

I don't know why your "hard disk performance" doubled, but I suspect
that you simply didn't measure it carefully (if at all) and what you
report is just wishful thinking.


And like I said if data is backed up properly why worry?


I'm entirely with you regarding backup. That's a necessity whether or
not you use RAID0. However, there is always a risk of backups not
restoring properly, getting lost, etc. Having backups is great;
relying on them to always be there working properly when you need them
is not so great.

And restoring from a backup takes time, and there can be a cost
associated with that too.


There is a much higher risk of losing data to a Windows failure than a
hard
drive failure.


I don't agree, but it doesn't matter, because it's irrelevant. The
point is simply that RAID0 increases the risk. And since it increases
risk for little or no benefit, it's not worth taking the risk.



Yes a stripe setup does increase the risk but the trade off
in performance increase is most definitely worth it.


Once again, I disagree. The performance increase is somewhere between
tiny and non-existent. That's why I took it off my computer here.



The only way I might
not do it is in a business environment.

If you want performance, raid/0 (Stripe) is the answer.


It produces very little additional performance, but greatly increases
the risk to your data, since if any drive in a stripe is lost, all the
data on the stripe is lost.

I recommend against it.

Gurus,

On a machine with two SATA drives, is there any performance gain by
running applications off of the second SATA disk? I understand that
SATA
is serial in-line technology, that being said, if all the reads and
writes
have to come through the same controller, then perhaps running
applications off of the second SATA disk might actually result in a
DECREASE in total system performance?
