Flash Drive are Not Secure in Deletion
Is this a potential problem?

 12:36 am on Feb 22, 2011 (gmt 0)

In research that has important findings for banks, businesses and security buffs everywhere, scientists have found that computer files stored on solid state drives are sometimes impossible to delete using traditional disk-erasure techniques.

Even when the next-generation storage devices show that files have been deleted, as much as 75 percent of the data contained in them may still reside on the flash-based drives, according to the research, which is being presented this week at the Usenix FAST 11 conference in California. In some cases, the SSDs, or sold-state drives, incorrectly indicate the files have been "securely erased" even though duplicate files remain in secondary locations.

When replacing a ssd, I plan to first drill holes through all the chips then smash them with a security hammer.

Yes, just don't use the hammer indoors in case it slips off the disk and makes a whole in your nice tiled floor.

Sounds obvious doesn't it, and yet.....

yes you have to physically destroy the disk, i actually recommend this for any drive no matter what tool you've used to wipe it.

Interesting followup...

well the 1st thing I think of would be to remove the SDD controller and have one for "forensics" that does not start this process. As long as you don't power on the drive with the OEM firmware the data isn't going anywhere.
