yes and no..

as work production servers tend to use smaller enterprise-level disks (Fibre Channel or other) they have a lower unrecoverable read/write error occurance than high capacity consumer drives (which is what I'm using)

statistically speaking, the larger your RAID 5 array, and the larger the size of the disks, the greater the probability of both a disk failure and a failure during rebuild due to an unrecoverable read/write operation.

factor in the fact that I'm using consumer drives that have a higher MTBF and Higher rate of unrecoverable read/write operation, I have a significantly greater risk of data loss using RAID5

And with mirroring, sure there's still that chance of data loss, but dataloss is usually just partial.

We'll see how the RAID 5 works to start... if there's a performance issue, it's a moot point.
