Somewhat OT: RAID 0

[None]

With the risk of adding fuel to the current controversy:

http://www.anandtech.com/storage/showdoc.aspx?i=2101

Excerpt from the 'Final Words' section:

"If you haven't gotten the hint by now, we'll spell it out for you:
there is no place, and no need for a RAID-0 array on a desktop computer.
The real world performance increases are negligible at best and the
reduction in reliability, thanks to a halving of the mean time between
failure, makes RAID-0 far from worth it on the desktop.

There are some exceptions, especially if you are running a particular
application that itself benefits considerably from a striped array, and
obviously, our comments do not apply to server-class IO of any sort. But
for the vast majority of desktop users and gamers alike, save your money
and stay away from RAID-0.

....

Bottom line: RAID-0 arrays will win you just about any benchmark, but
they'll deliver virtually nothing more than that for real world desktop
performance. That's just the cold hard truth."

When I can load OOwriter in about 3 seconds compared to 17 seconds for a
single drive in MDMA mode 2, I'd say all their analogy is pure BS.
If you do nothing but check email and surf the web, then it's obvious
overkill, but for many desktop apps it's a real performance increase.
transfer rates are transfer rate and twice as fast is still twice as fast.
And if you need a single large storage area, it beats the other options
speed wise.

It looks as though they set them up wrong.

Try this. It doesn't test with apps, but seems to indicate that the "pure
speed" results Anandtech got are faulty.
