One thing other answers have missed is that some ssds encrypt data before writing and obviously after reading (this prevents a swap the storage controller type attack) A secure erase on such a device consists of changing the read/write key. Takes milliseconds. Irrevocable (unless you find a way to read previous contents of the key storage)
I use it on every phone handset at work… I guess it’s the switch PoE not the pc mobo but the effect is the same. If you are talking pc mobo PoE I guess it could be handy if you had a PoE camera…
