Is Raid 0 basically mirroring?

'cos that's what I've got on my Dell 2.66GHz dual-core with 3GB of RAM,
and it's pretty snappy.

My understanding of the mirroring is that for disk-reads especially it
should help quite a lot, since the disk controllers can read half the
file from each of the 2 disks, thereby cutting your read times fairly
significantly.

I don't know if it's actually possible to buy single core CPUs anymore?
Compared to when I used to run virtual machines on a single core CPU,
duals are essential for anything like that.

On the subject SATA Raid, my home machine has a couple of drives
configured in Raid 0 - and the machine seems really snappy.  I would
certainly agree that Raid is an excellent way of boosting your machines
performance for not much extra overall cost.  You may find Raid 0 a bit
unreliable (which reminds me - I should do a backup) for a work machine
- but you could go for Raid 5 (with 3 or more drives).

It somewhat sucks to be buying a new machine at the moment because of
the value of the NZ dollar.  The CPU I purchased 3 or 4 months ago is
actually more expensive now (a 3GHz Core 2 Duo).

I guess any recommendation is going to come down to how much (or little)
you want to spend.
