Samsung PM1643a 3.84TB 2.5" SAS SSD

The Samsung PM1643a is an enterprise solid-state drive with 3.84 TB capacity, specifically engineered for mission-critical server and workstation environments. Utilizing a robust SAS 12Gb/s interface, this drive ensures the high bandwidth and consistent performance necessary for demanding, high-throughput applications. It operates in the industry-standard 2.5-inch form factor, enabling broad compatibility within modern server chassis and storage arrays. The SSD uses TLC NAND flash technology and includes full support for error correction (ECC).

Sequential throughput metrics reach 2100 MB/s for reads and 2000 MB/s for writes, supporting the rapid data processing required by enterprise workloads. For latency-sensitive operations, the drive delivers 450,000 IOPS for random reads and 90,000 IOPS for random writes across a 100% span. Reliability is maintained through advanced features, including enhanced power loss protection, end-to-end data protection, and a mean time between failures rating of 1.8 million hours, stabilizing performance under continuous load.
