CrystalDiskInfo 6.1.12 Readout:

For the ASUS Hyper Express 256GB drive, the readout on CrystalDiskInfo 6.1.12 shows that both NCQ and S.M.A.R.T. are enabled, but this drive does not support TRIM and the interface does not show up as SATA Express. The firmware version that we are running at the time of testing was 140324. ASUS was not sure what the best way to secure erase this drive is yet and there are no drive maintenance tools available yet.
