No thats the point, hardware failures on the same machine/rack/psu/site are not independant.
A power supply spike that kills drive 0 in a RAID will probably kill the mirror drive 1 as well - that's why RAID isn't a bckup stratergy
- Tamerlin 16y agoYou missed the point -- a power supply spike isn't a hard drive failure, even if it kills a couple of drives, it's a power supply failure. I was explaining a common misconception about statistics, and using hard drives and DIMMs as examples.
