Wieso ist NVMe User Data Erase und Cryptographic Erase so wichtig?
User Data Erase and Cryptographic Erase are two different standards that are supported by almost all NVMe hard drives. Unlike BSI3, BSI VS etc., these are firmware-based deletion procedures that run internally in the hard drive and are programmed directly into the firmware by the hard drive manufacturer. The two methods therefore also reach areas of the hard drive that normally cannot be addressed directly. These include, for example, cache and swap memory. This memory can also contain parts or even entire files. In order for the medium to be safely deleted, these must also be overwritten.
NOTE:
NVMe is a software protocol and not the port or storage technology.
Most of the time SSDs on the PCI bus are controlled with the NVMe protocol.
Settings in toolstar®shredderLX - Recommended method
In toolstar®shredderLX and in toolstar®shredderWIN, the method preset by the program is the Recommended method. This method automatically decides which is the best erasure method supported by the media based on the type of hard drive. In toolstar®shredderLX magnetic hard drives (HDD, USB, SD card, etc.) are included BSI3 erased and SSD hard drives with a combination of SecureErase and random numbers. Within toolstar®shredderWIN all magnetic hard drives are also deleted with BSI3 and SSD hard drives with it Random numbers and zeros.
However, NVMe SSDs do not support the SecureErase method and therefore the recommended method is only partially suitable for these types of drives. To securely erase NVMe SSDs, you must use an NVMe standard. These are NVMe User Data Erase and NVMe Cryptopraphic Erase. Both standards are comparable to Enhanced SecureErase or SecureErase.
