Endurance and Reliability Features

Endurance is measured in Drive Writes Per Day (DWPD), and this SSD’s 3 DWPD rating ensures it can handle sustained heavy workloads without premature wear. Reliability is further reinforced through advanced technologies integrated into the SSD:

Power Loss Protection (PLP)

In case of sudden power interruptions, PLP ensures that in-flight data is safely committed to NAND, preventing data corruption and minimizing downtime. This is essential for enterprise applications where uninterrupted operation is critical.

Wear-Leveling and Error Correction

• Wear-Leveling: Evenly distributes write operations across NAND cells to prolong the drive’s lifespan.
• Error Correction Code (ECC): Corrects errors before they impact system performance or data integrity.
• End-to-End Data Protection: Safeguards data from host to NAND, reducing the risk of silent data corruption.
