What is the protocol you should use with SSDs that you’re storing? Should you:
- power up the SSD for an instant (or for some minutes?) without needing to read anything?
- or power up the cells where your data resides by reading the files you had created on the SSD?
- or rewrite the cells by reading your files, deleting them, and writing them back to the SSD?
partclone.filesystem --source /dev/sdx --clone --output /dev/nullThe correct protocol is to copy the data to a more durable medium and store that.
Any decent SSD will background rewrite itself over time at an appropriate rate. Detecting that it needs to do so after 2 years in storage seems trickier to get right (no realtime clock) and trickier to test.
I’d be curious to know how quickly the drives in the article “heal” themselves if left plugged in. There’s nothing wrong with the hardware, even if they did lose a few sectors.
If you really want to create a correct protocol, you can accelerate nand aging by sticking them in an oven at an appropriate temperature. (Aging speedup vs temperature curves are available for most nand devices.)
