If you choose to run RAID member drives all the way to failure, then you 
need to have a reasonable expectation that the remaining drives have 
enough reliability and the RAID has enough redundancy to protect the 
data until the sysadmin notices the failed drive(s), the sysadmin 
replaces the failed drive(s), and the RAID resilvers.


Given the OP's situation -- 8 consumer SSD's, same make and model, 
possibly from a defective manufacturing batch, all purchased at the same 
time, all deployed in the same RAID-6, all run 2.5 years 24x7, and all 
suddenly showing lots of SMART warnings -- I would not have confidence 
in that RAID.
