There are two levels of Secure Erase: standard and enhanced. Standard Secure Erase will delete the map of the SSDs controller. Although the data will still exist on the NAND, the controller will see no data. Enhanced is the most secure version of secure erase by writing random bits to the entire drive multiple times. This ensures that none of the data will be salvageable. Performing a Secure Erase on your drive is destructive and should be used cautiously because it will make it extremely difficult to nearly impossible to read the data on the drive.
PNY Does not provide a program to Secure Erase however any program that advertises this function will work with PNY SSD's
