Does raid 0 put any extra stress on the drives. |
No. Each drive works just as hard (but no more so) as it would in a single
disk configuration. The only difference is that both drives are working
together. It's actually the other types of RAID array (striping/mirroring
etc.) that cause the drives to do "extra" work.

If they work harder would extra cooling help them not to fail. |
They don't work harder so this point is largely moot. However, whether you
use a single drive configuration or a RAID array, it's always worth making
sure that the disks are adequately cooled. Most modern ones will report
their temperatures to utilities like MBM, SpeedFan and the drive's own
utilities, so it's relatively easy to be sure about the cooling aspects.

Hard disks are generally pretty reliable. Apart from a few spurious
exceptions, there's no reason to expect you should run into problems.

Also with raid 0 from what i read i will have 2 160 drives

Correct.

if i raided them to raid 1 i would only have 160 gigs while the other
drive would be for backup purposes. |
RAID 1 isn't backup in the traditional sense. It only provides you with
backup in a given set of scenarios (e.g. one of the drives suffers a
physical failure). If you, for instance, deleted a file off a RAID array,
and then wanted to recover it, you'd still be screwed as the file would be
deleted off both drives at once. As such you might still require a
"conventional" backup solution.

Frankly, you don't really *need* to do it. Modern SATA hard disks are fast
enough for pretty much any application you are likely to want to do. The
historical uses for which RAID 0 used to be necessary - for instance
real-time DV video capture via Firewire, can now be done quite comfortably
on a single typical modern 7200rpm drive.
Indeed, given a pair of fast modern drives, it may well be that you would
obtain better performance in some scenarios by configuring the disks in
conventional non-RAID mode, depending on what you do with your system. Think
carefully before you proceed!
