What are the chances for failure of 2 drives at the same time on a 4 drive raidz 1?
I've read that chances are 1 from 10 drives to fail over a period of time of one year or more.
What is the best approach to having more space but still have redundancy?
3 drives in raidz 1?
6 drives in raidz 2?
I would like to use a pool of 4 x 1.5 TB drives for a mini backup server.
I've read some posts regarding ZFS here on forum and on http://www.solarisinternals.com/ but I need your opinion on that: chances of failure for hard drives from your experience.
