I mentioned that in the other thread ("SDD, what features..."), I plan
to sum up the articles tomorrow. I'd guess he means that test ;)

If you mean TBW by "lifetime": All above factor 2, best: over 18. Ok,
those were the "brand models" (1 Crucial, 1 OCZ (Toshiba), 2 Samsung
and 2 Sandisk, and 2 drives of each model)...
Fun fact: one of the test PCs died and killed two of the 3 remaining
SSDs, the second Sandisk Extreme Pro (the first had died already) and
the first Samsung 850 Pro. The remaining second Samsung 850 Pro in the
other Test-PC was still being hammered 4.5 months later with 8 PeBi
written (all drives were 240/256 GB), but showing first "Uncorrectable
Errors" via SMART.
The test also included the failure mode as well, e.g. "dead as a
brick" in a moment, warning signs via SMART, failure to write but
still readable etc.
The mag followed that up with a test of el-cheapo SSDs ... which I'll
include in my summary.
