> This way there is never any chance unencrypted data is written to the flash. That has nothing to do with the SSD controller. The OS never has to send unencrypted data to the SSD in the first place. Offloading encryption to SEDs (self encrypting drives) is probably more helpful in server environments where you have dozens of disks and mind-bogglingly large amounts of data flowing around, but SEDs are completely uninteresting for consumer applications, and if Apple is integrating the SSD controller directly into their SoC, then it's effectively no different from using an integrated crypto accelerator prior to sending data to an external SSD controller.
