nobody should ever be using raid5 anymore, and that's been true for many years: http://www.zdnet.com/article/why-raid-5-stops-working-in-200...

the use cases for raid5 have pretty much been replaced with raid6 plus hotspare.

There's a followup to that article that says Raid 6 won't be recommended by 2019.

Yeah, that is indeed scary, and something to be taken into account for disaster recovery planning. Off site backups of systems need to be designed so that the whole RAID array can be physically destroyed (fire, flood, theft, axe, etc) and recovery will not take a ridiculous amount of time.

The wise sysadmin mantra of "RAID is not a backup" must be kept in mind at all times.

ZFS in RAIDZ2 mode.

Unless 3 drive controllers die simultaneously, you can survive finding faults during a full rebuild.
