Speedy RAID0

[RoS]

Is this an oxymoron? Just how much faster is RAIDO in real life terms on a
Win XP system. I'm reading conflicting statements and am wondering if my
RAID0 setup justifies (in terms of speed) the loss of having a second drive
for fail/safe back-ups. I don't have any apps that can test the relative
speeds of a RAID0 setup against a non-RAID0 setup - and wouldn't
particularly want to spend hours re-configuring/re-installing everything to
find out.

In general terms should the benefits be substantial - or are we talking of 1
or 2 percentage speed gains? Working on graphics files in Photoshop is
where I'd be hoping to see worthwhile gains in procesing times over working
with a single drive.

TIA

It depends on the system so no one can answer your question. You would have
to test your system with and without RAID 0 and compare the results. The
things that affect it are: hard drive controller, hard drives, motherboard
chipset, CPU, and ram. With most on board PATA & SATA controllers there is
not a significant speed increase. There is a much greater chance of data
loss with RAID 0. If any of the drives fail you lose all the data on all the
drives. My experience with graphics programs is the speed of the CPU and
amount of RAM makes more of a difference than hard drive throughput. Good
RAID controllers that can significantly increase speed tend to be SCSI,
expensive, and require expensive drives.

Right! Processing photos is CPU and RAM dependent once the picture has been
loaded (which actually takes but an instant on today's computers).
