> Think about it as an SSD manufacturer - what's the easiest way to wipe a drive? That's not the reason why encryption is always on. Flash endurance is; encrypting the data before FEC means that it will have a random distribution, which avoids pathological worst cases with certain workloads. You could also use a different (cheaper) scrambler than AES (like CPUs do [1]), but since encryption is a marketable feature... [1] Which are also switching to using AES and offering memory encryption in current mainstream architectures.
