You'll need to do this with NAND-based devices as well, as NAND tends to lose data integrity as data is repeatedly read out.

What is an issue is if you leave the SSD unpowered for a few months and the cells leak enough charge to be unreadable.
- mjevans 7y agoI suspect most SSD firmware actually does automatic old-age scrubbing of somekind within the firmware. This theory seems likely confirmed with your offline decay theory.
