You CANNOT wipe most solid-state disks. That includes NVMe, SSD, USB flash drives, etc.

The controller system on the disk does not write all zeroes just because you told it to, nor are blocks/sectors a physical map like they are on magnetic media. The wear and write management features baked into the storage system stop your wipe from succeeding

If you need to store information to flash storage that you need to protect from physical access later, encrypt the disk before you store the data. Or have plans to physically destroy the chips.
