Might try penicillin.
nice info, I didn’t know this. I’m using SSD for my primary drive and HHD for storage
I suppose you could just take them 100 or so miles out in the ocean and then blow them up.
Definitely encrypt.
But I’m kind of at a loss how new “data” can coexist with overwritten data. On magnetic disks, you analyze the disk surface around and beneath the last written data for residual magnetism since every write does not follow precisely the same path or depth of previous writes and old magnetism can spread a little. How does something analogous happen to discrete capacitors?

love my SSD in my M11x
This is an issue, but it can be solved.
Within a year, SSDs will have secure erase algorithms *built in* at the flash chip level. The semiconductor industry is very good about that sort of thing. I’m confident that what they come up with will make SSDs even easier to secure-erase than magnetic drives.
The challenge will be to keep the gubmint from mandating a backdoor method for THEIR access. ;-)
I’m reading this from a laptop that has (as it’s only drive) an SSD drive that is also an encrypted drive.
I was going to post this at Information Week, but since they insist on a login I’ll do it here:
The solution is in fact physical destruction of the drive when it fails or is upgraded. It will require enough force or other destructive action to destroy the flash chips. For instance, hitting the drive repeatedly with a sledgehammer until the chips are fragmented should be more than sufficient.
Incinerating the drives would probably be even better from an information security standpoint, but would require a special high temperature device in order to eliminate toxic combustion products.
Such precautions make the risk of using SSDs no worse than unencrypted rotational media, which are also easily compromised if there is physical access to them. Drives containing classified information have received these kinds of treatments for many years.
