From the nwipe (what this uses) page:

The ShredOS page suggests the use of hdparm for SSDs but things are fairly complicated:

These days I'd just take a hammer to a dead SSD and smash the chips to powder.

I haven't found a technical whitepaper on it but supposedly NAND/NOR flash goes void immediately when reaching a certain high temperature below the melting point of copper. Something about putting a blow torch to the chips for a brief moment...

Hammer sounds easier to verify the destruction worked.

Startup idea: Industrial portable just drill-holes-to-you-device-if-needed & then just-add-water data-erasure bags (single-use, safe to throw away). Would save lots of equipment weight.

Yeah:

> Given that the support for sanitization is optional and not a mandatory aspect of the respective standards the support accross vendors can vary largely. The following table does not claim or warrant to be complete, it is highly advised to always validate the information with the manufacturer:

It'd be nice if the INCITS/SATA/SAS folks could make it mandatory.
