RAID 0 or RAID 1

Richard Cranium

Planing to build new PC. Core i7-930 CPU. Main function will be
movies - commercial and home - HD and otherwise. Lots of moving
copies of movies from original sources (DVDs or cameras) to HDD
temporarily for viewing - sometimes burning discs too. Considering
two options:

1. RAID 0 configuration with three smaller (~320Gb) hard drives, plus
a 1Tb HDD as a clone.

2. RAID 1 configuration with two identical HDD - somewhere between
500Gb and 1.5Tb, depending on the best deal available at the time.

I'm thinking that Option 1 above will give teriffic I/O performance,
but will it be much superior to the more typical Option 2? Any
thoughts appreciated. TIA.

Well you are asking Apples and Oranges, no? i'm no expert, but if
RAID0 is for performance, while RAID 1 is for security, then you have
two ends of a spectrum. Pick what you want: speed vs safety.

The real question (IMO, as I was thinking the same thing) is whether
with RAID 0 you can backup using Acronis Backup, a third party
software. I heard something about RAID 0 data not being readily
understood by backup programs, though I may have misunderstood.

The 1Tb clone in Option 1 is the equivalent of the RAID 1 security
blanket. My issue is whether I will see a significant enough
performance increase from the three HDDs striping to warrant that
approach.

Yes, you will (see the performance benefit). Go with RAID 0, all the
backup programs work with it as a single drive. I've had a 3-disk RAID 0
for some years now and it still out-performs the very best single-disk
solutions...and is not much worse than even SSD.
