    I like Boot repair x64 very much but NVMe support is missing. Sometimes it detects the drive and sometimes it doesn't.

    That would be setting the drive up with the worst performance possible. I think what OP is getting at in regards to secure erase is for the SSD's NAND cells to be marked empty.

    Same here, no need for any special tools.

    Any piece of software marketed as 'forensic'/nsa-proof is very much redundant and a gross waste of dollars. In a highly theoretical scenario you might measure the tiny left-over capacity of each cell, requiring industrial-size microscopes ($100k or more) and just maybe you might recover some snippet here and there. Realistically though ... all you need to do is simply wipe a drive; no software will be able recover a single byte. Or, similar to @Starlight5 's suggestion, fill it to the brim with non-sensitive data (if you're truly that paranoid). Can skip the encryption and erase part then, too.

    Corrected my post. I'd like to add that SSD will need a TRIM treatment afterwards if USB enclosure doesn't support TRIM pass-through. Easy way of restoring SSD performance after use over USB without TRIM is quick-formatting the whole drive, then deleting the partition, and letting it sit for a while.

    Yes. Timing may depend on the use of the SSD's garbage collection routine to empty out discarded pages.
