SSD's wear out based on writes per block.   they distribute those 
writes, but once each block has been written X number of times, they are 
no longer reliable.

they appear to still be working perfectly, but they are beyond their 
design life.   soon or later, if you continue the amount of writes 
you've been doing, you'll get back errors or bad data.

I would plan on replacing those drives sooner rather than later.   5 
years was a good run.
