As for the corruption, could it be degradation from repeated reads of

Read Disturb. I Did not know SLC did that. It just takes 10x as long as MLC, on the order of a million reads. Supposedly erasing the block fixes it. It is not a permanent damage thing. I was seeing ~9 hours before failure with heavy writes. ~4GByte/hour =3D 2M pages, total ~18 million reads before errors in that last block showed up. Cool. Now we know. Thanks. Mike Hench
