It does not have a battery = it does not have a BBU.
Samsung can dance around that fact all they want, but it won't change.

The lack of BBU does not bother me though (there are backups for
worst-case scenarios), and that server is on UPS anyway. Possible
firmware bugs (these things are new, this unit was produced about a year
ago), and, of course, the scourge of modern Enterprise SSDs -
temperature loss - these I'm wary of.
