Does anyone know if there's a utility that monitors SSD health? I've a 512GB SSD, which I'll probably keep for a while, but I don't like being in the dark about how far along its lifetime I am
smartmontools can be utter crap when it comes to interpreting SSD data. Some manufacturers seem to deliberately program the SSDs to report SMART data incorrectly, or report correct data under the wrong code[0], just to encourage you to use their proprietary software.
I have an 840 Pro in one server that works okay with smartctl, but the Corsair Neutron GTX in a different server has readings all over the board that are utterly useless.
