That is a really strange comment to me. No SSDs have batteries.
Almost no RAID cards have batteries anymore. Supercapacitors have
obsoleted the battery for such purposes. All SSD power loss
protection is supercaps. And if you try to buy a modern RAID card
with a BBU you will mostly just find cards with supercaps instead.
But OP was asking about SSDs not RAID cards so even that nuance
doesn't make much sense.

But okay, your SSD doesn't have pink elephants either. Samsung can
dance around that fact all they want.
