[Coco] CF and SD life expectancy

[Mark Ormond]

Go raid 6 or zfs. 
(Never trust raid as a way to keep your data safe. A good backup that is tested is the only way to insure your data is safe. I sell A LOT of servers,
And tell this to every customer. Raid is a good way to keep downtime to a minimum.)

Same here.

My favorite:  LTO tape.  Fast and incredibly reliable.

I'm not sure I even trust RAID 5 anymore.  I recently had one drive in an 
array fail on my Linux workstation, followed quickly by a second during 
the rebuild!  As the capacity of drives gets larger, the chances of this 
happening increase.  Fortunately, I had a recent tape backup and didn't 
lose anything critical.
