1+0 is different then 0+1

you can Stripe 2 drives,
Stripe two more,
and mirror those two stripes together.

1 fails and performance suffers
versus
mirror 2 drives
mirror 2 more
stripe those 2 mirrors.
1 fails and no performance hit is taken.

In my old video game box i just went with 0 as i didn't care if i lost my safe points or had to re-install the games. in a 1+0 or 1+0 depending on which drives die you can lose 2 drives and not lose any data. where as a RAid 5 if you lost 2 of 4 you lost everything. Course with 1+0 or 0+1 you could lose 2 of 4 and lose everything, depending on which drives.

Sure you lose more storage space in either 1+0 or 0+1 but you are (slightly) less likely to lose data. What's more important to your usage not losing data, or not losing as much space ?
