SLC, MLC, TCL, QLC have different properties as well - again not too relevant to this discussion.ġ. Solid-state drives store their data by means of setting the state of a gate (oversimplification) and the previous state of a gate can not be determined. Mechanical drives store data in a physical state on a sector and that physical state stays the same until a change is requested.Ģ. Here are some things to keep in mind when it comes to data destruction (speaking as someone that used to perform forensic data acquisitions) for mechanical drives vs solid-state drives.ġ.
Oh my gawd, here we go, more misinformation being perpetuated by people that do not know what it is they do not know.įor mechanical drive, use a program like hdparm or bcwipe, perform a one-pass write of 0's or 1's to all sectors and the drive is securely erased.įor SSD drives, use a SSD tool like Parted Magic which will use the ATA Secure Erase function that is built-in to all SSD drives.
