more by erasures and writes over time. That is, it determines actual cell wear, not
simply assumed wear normalized to write/erase events. The controller employs
this information in its superior wear-leveling algorithm along with its ongoing
record of writes and erasures, to ensure each block is impacted by P-E cycles no
more than the average. The result is an SSD that is far more reliable across its
full capacity and over a far greater length of time. The controller uses both static
and dynamic wear-leveling algorithms to globally manage cell degradation to
approximately 2% between least worn and most worn cells or to the value
specified in the S.M.A.R.T Wear Range Delta command (ID=177, Opcode=0xB1)
2.5.3.2 Write Operation Reduction
The controller uses intelligent algorithms to minimize P-E cycles through
aggregation, virtualization, and difference processing. It is uniquely effective in
reducing the wear and maintaining the reliability of the overall pool of Flash
memory blocks by intelligently minimizes re-writes of identical data, to maximize
the effectiveness of the wear-leveling process.
2.6 Data Security
Element SSD supports AES-128 encryption and ATA Secure Erase features to
protect sensitive data.
