4. Endurance, Reliability & Data Protection

High-Endurance Architecture

• Workload Classification: Write-Intensive (WI) / Endurance Class

• Drive Writes Per Day (DWPD): 10.0 DWPD (Calculated over a 5-year production deployment)

• Data Write Lifecycle Capacity: ~3.65 Petabytes Written (PBW)

Enterprise Integrity Safeguards

• MTBF (Mean Time Between Failures): 2.5 Million Hours

• UBER (Uncorrectable Bit Error Rate): Less than 1 sector error per $10^{17}$ bits read

• Dual-Port High Availability: True active-active dual-port pathways eliminate single connection vulnerabilities, offering seamless path failover down to the SAS backplane.

• Power Loss Protection (PLP): Discharges onboard hardware capacitors to flush volatile in-flight caching registers securely into physical NAND non-volatile logic blocks during unforeseen server power outages.

• Data Path Safeguards: End-to-End Data Protection with background error scrubbing prevents silent bit errors or cross-talk corruption.
