Not if the single drive is manually mirrored to another drive. I use 3 drives in RAID 0 for my OS and programs. All my media is on a 1tb drive that I manually mirror with another 1tb drive.
So say you have 2 disks that you can predict the failure of, one (disk A) will fail in 3 months, one (disk B) will fail in a year.
If you have both disks individual from each other, and you have all your data on Disk A, and manually copy it over to Disk B each month - Drive A will fail in 3 months and you will have your backup on Drive B. All is good, replace Drive A and move on.
If you decided to RAID0 these drives for storage, all your data will be split between the drives and Drive A will fail in 3 months taking all the data on Drive A and Drive B with it. No backup, total loss.
The choice to RAID isn't increasing the failure of Drive A (still 3 months), but it is increasing the likelihood that your backup solution will lose your data.Edited by _02 - 7/29/11 at 10:39am
