And again, there is no actual numeral "1" or numeral "0" saved to the disk. On SSDs, a "cell" is either charged (to represent a "high" or a "1"), or not charged ("low" or "0"). There is no actual numeral "1" or numeral "0" saved to the disk. To illustrate, a particle arranged in a North/South orientation may represent a "1" while a particle in an East/West orientation may represent a "0". On a HD, a magnetic charge from the R/W head "physically" orientates the magnetic particles on the platters in patterns that represent a 1 or a 0. And that is why wipe programs should not be used on SSDs.Īnd on SSDs it is NOT about putting a 1 or 0 in the storage location. Since wear leveling prevents a wipe program from touching every storage location on a SSD, a wipe program does NOT ensure security. In other words, for security (or privacy) reasons. Sadly, folks seem to focus on the wear (limited number of writes) factor of SSDs but that is a misguided focus.įor what purpose do we wipe a hard drive? To ensure no previously saved personal data is left behind. This is due to the various load leveling features with essentially all modern SSDs - and this is exactly why a "wipe" program should NOT be used on a SSD. Second, on a SSD, no it won't wipe all the free space and that IS the fear! That is, the fear is some personal, sensitive data might be left behind. So nothing to fear - that is what you want. And more and more motherboard BIOS firmware include "secure erase" right from the BIOS Setup Menu.Īnd if you really, once and for all want to ensure your data is unrecoverable, use a drive shredder.Ĭlick to expand.Huh? I don't understand what you are saying.įirst, on a hard drive, that is exactly what a wipe program is supposed to do. Most SSD makers provide free secure erase utilities on their websites. If you want to ensure all previously stored data on a SSD is unrecoverable, use Secure Erase. So, if you want to ensure all previously stored data on a hard drive is unrecoverable, use a wipe program. And a wipe program is "ineffective" because the wear leveling features prevents such wipe programs from writing a bunch of random 1s and 0s to each and every storage location. So a "wipe" program - that is, a program that over-writes files - is "unnecessary" because the erase/delete function used on SSDs does not leave data behind in the same manner as a hard drive for a recovery program to restore, nor does it leave residual magnetism behind that Agent 007 could read. The bigger problem, as I see it, is TRIM, overprovisioning and wear-leveling features used on SSDs will actually prevent the wipe program from touching each and every storage location on the disk - which is necessary to ensure "all" previously stored data has been obliterated. So what? Why are you trying to secure-erase a SSD anyway - except to get rid of the drive? And even if you went to super-duper military specs and selected 256 passes. A small handful of "writes" is not going to hurt, or put excessive wear, on a SSD - even an older generation SSD. Most "wipe" programs default to 1 or maybe 3 passes. Windows 11 pro 圆4 (Yes, it's genuinely a good OS) OpenRGB - ditch the branded bloatware!Ĭlick to expand.I would say "unnecessary" and "ineffective" rather than "bad" - at least for newer generation SSDs.
