A Caveat About SSDs
One failing that bothered us in all these apps—including our top picks—is that they didn't even warn us that we couldn't recover files from an SSD. It's easy for an app to tell whether a drive uses spinning-platter or SSD technology, and easy to tell whether TRIM technology is active in a drive. All of the software we reviewed, both on the Mac and PC, misleadingly told us that they were able to recover deleted files from SSDs—and then disappointed us by providing corrupt and unusable files instead of the ones we wanted. We hope that the next generation of data recovery software is redesigned to make it clear that we can't hope for file recovery on SSDs unless the deleted files are safely in the Recycle Bin—where, of course, they're easy to find without using recovery software.

The reason that data recovery software can't recover data from SSDs is simple. Virtually all current SSDs use so-called TRIM technology that increases efficiency and disk life by clearing disk sectors that are not being used. One result of this is that the data can't be recovered by software, even if the file system retains its record of the sectors where the data used to be. With traditional spinning hard drives and USB flash drives, file recovery is relatively simple. Recovery software can find the location of a file's data even if you've emptied the Recycle Bin, often even if you've reformatted the disk. But once a file is deleted from an SSD, and the Recycle Bin has been emptied, there's no hope of ever getting that file back again, unless you have a backup somewhere.

Goed topic, hoewel ik maar een relatief kleine backup van 1TB met veelal onbelangrijk spul heb ik hem wel in zowel dropbox als google drive staan, wat ik doe is dat ik mijn backp als Rar archiveer met een sterk password, ik hoef dus ook niet bang te zijn dat dit soort diensten erin gaan snuffelen.
