Enterprise Capacity 1.92TB

The Samsung PM863a is a 2.5-inch internal SSD built for read-intensive enterprise workloads. Its 1.92TB capacity suits database servers, virtualisation hosts and content repositories that demand consistent throughput.

2.5-inch SATA Build

The standard 2.5-inch form factor fits common drive bays and backplanes using a SATA 6Gb/s connector. With 3.45W active power and a 0°C to 55°C operating range, the drive integrates into existing enclosures without extra cooling or cabling changes.

Endurance Rating 2000000 Hours MTBF

A 2,000,000-hour MTBF and triple-level cell NAND indicate the drive is engineered for sustained random read performance of up to 55,000 IOPS. This reliability figure is the primary metric for deciding whether the PM863a matches a given deployment's durability requirements.
