Flash-based solid-state drives nearly impossible to erase

Is this a security risk?

Researchers from the University of California at San Diego delivered a paper at the FAST-11 Conference in San Jose, Calif., last week that shows it's almost impossible to reliably erase data from a solid state drive.

The tome, "Reliably Erasing Data from Flash-Based Solid State Drives" (PDF) [1], goes through all of the known techniques for erasing data and comes up short in every case. The study's method is straightforward: They put repeating data on an SSD or USB drive, tried using various erasing techniques, took the SSD or USB drive apart, and pulled raw data off the chips. If any of the original data remained, erasing didn't work.

There is a solution. A sledgehammer.

Any information that important would be destroyed even on a platter drive, should make recovering data easier.

Southchop mentioned you could not recover data from a dead SSD, sounds like it is more possible than a platter drive

Copy a huge file to it - forcing it to write over all the blocks.

When exactly did I say that? I did infact mention that SSD recovery is extremely expensive and complex. As long as the NAND chips are intact data can be recovered, if the data still physically resides in the chip of course. If you know anything about the way in which a SSD drive works then this would be obvious.

Any information that important would be destroyed even on a platter drive, should make recovering data easier.

So you're saying SSD recovery is easier? Lol. Wait until you see a quote for an SSD recovery, then you'll want to retract your statement.

You should get your facts right before you start blurting out random comments about technology, and people.

Hook line and sinker, so easy on the interwebs hahaha

dd if=/dev/zero of=/dev/sda should do the trick?

... should make recovering data easier.

It's much harder and also costs a boatload more!

A little bit of fun never hurt anyone.

How much does it cost to recover lost ssd data? How much does it cost to recover platter data?
