Erasing sensitive data on solid state disks

A reader asked me the following question:

I am wondering if you have any recommendations to destroy data on an SSD in accordance to DoD before we send them to recycle. We have a very strong degasser that use that will not only wipe the HD completely, but will destroy the electronic in the boards. SDD drive will not work in this. This is quick for our mass number of computer turnover.

I asked some of my colleagues in the hardware and enterprise communities concerning this and basically received two kinds of answers. First, if you want to recycle them, you should ask the SSD vendor how best to erase all data from the drive in a way that meets DoD standards. The vendor’s SSD Secure Erase function may be sufficient or it may not, but either way the vendor would be the best one to advise.

If you’re not concerned about recycling them however, you should just have them physically destroyed using an industrial hard drive disintegrator.
