I'm occasionally encountering messages posted to User Forums
that warn about total data loss if and when popular MLC and TLC SSDs
experience a sudden power loss.
In some instances, those SSDs actually "bricked"
(turned into non-functional "bricks").
For myself, I find it difficult to believe that end Users would
build a powerful workstation and then NOT power it with a
quality battery backup / UPS (uninterruptible power supply).
All of our workstations are powered by an APC UPS,
and that may explain why those workstations generally
do NOT experience sudden power loss; and, believe me,
our UPS units do switch over to batteries on a regular basis
(probably because of faulty 110V wiring in our building).
I'd like to open a broader discussion here concerning the
perils of sudden power loss and the likely effects on
the current installed base of SLC, MLC and TLC SSDs.
If SSDs are failing because of sudden power loss,
the solution may be as simple as installing a
quality battery backup / UPS unit.
In our experience with at least a dozen workstations,
powering all PCs with a quality UPS has the predictable
effect of prolonging the useful life of the entire PC -- all components --
particularly if the UPS is paired with a quality system PSU
and the 3 primary voltages stay well within spec.
