The most reliable SATA drives model from most reliable manufacturer 
during constant up, spinning and used in RAIDs  had about or less than 
3% failed in a course of over 10 years.  Most reliable manufacturer in 
my book that is: Hitachi, former IBM, later HGST, the production line 
now bought out by Western Digital.

I doubt there is same longevity statistics for SSDs. Also: hard drives 
have theoretically infinite number of writes into the same area, whereas 
SSDs have finite number of write operations into a given cell. In view 
if this difference any comparison can be argued as unfair.

I'm sure, people who have large number of SSDs for long time will add 
their observations. I was happy with Samsung 2.5 inch SATA SSDs so far.
