[SGVLUG] scary RAID 5 going going .. soon 2 be gone?

Hi,

well not quite, however you want to read this
article

summary:
As Hard Drives get larger, and
unrecoverable read error (URE) rate
remains about the same, the chances
of being able to recover from a
disk drive failure on a RAID 5
system goes down (i.e failure rate increases )... 
so much so that you may expect to
not be able to reliably recover.

scary math, especially considering what a PITA
it is to backup large amounts of data.
