The testing was at the drive level without an OS like ext2. The test was with no flush (with flush test is easy to pass). Without PLP, the pass criteria is that the data that was buffered can be either the older or newer data and not corrupted or previous data. All the other blocks on the SSD should remain unchanged. Its trickier that you think because MLC/TLC NAND could corrupt other blocks due to NAND structure and we had to deal with that. Then you also have to worry about system data in the NAND doesn't get corrupted.
