while I am for reusable, there is no way I as a consumer can trust the overwriting bit of bits

The game changed a lot when we started to use SSDs. Wear leveling and rewriting while writing means that blocks are moved around, quite a lot.

There is also parts that are "spare blocks" which can be used as the device gets older etc etc.

The best way to ensure you can reuse a storage device is to turn on encryption, and then do your best to delete the key part of this
