Researchers at the University of California at San Diego (UCSD) say data on SSDs is more difficult to erase than that on HDDs, in their study "Reliably Erasing Data From Flash-Based Solid State Drives."
The study tells how sanitising SSDs of data is a difficult task-- if not nearly impossible. Not even overwriting data several times ensures data erasure, as the researchers say they still recovered data on some products. As the paper says: "all single-file overwrite sanitization protocols failed: Continue reading...
