WebBefore 2 NVMe drives were wearing at about .75% a day been running ths ssd for at least a week and no wear has accumulated... On top that drive had been in use else wear for a few years so I would have expected to see at least 1% wear by now. Web78. Yes. If you do a normal format, the old data can be recovered. A normal format only deletes/overwrites a tiny bit of filesystem metadata, but does not overwrite all of the data itself. The data is still there. This is especially true on SSDs, due to wear levelling and other features of SSDs.
