I don't know how to interpret the "Pre-fail" notation for the other
attributes.
AIUI "Pre-fail" indicates the drive is going to fail soon and should be
replaced.
Only if the attribute hits the "failure" threshold, whatever that
happens to be or mean for that particular attribute.
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.
