Samsung PM1643a 3.84TB 2.5" SAS 12Gb/s SSD

Overview

The Samsung MZILT3T8HBLS-00007 is a 2.5-inch SAS solid state drive designed specifically for enterprise environments that demand high capacity and reliable performance. With 3.84 TB of storage and a 12 Gb/s SAS interface, it integrates seamlessly into server and storage chassis to accelerate data-intensive tasks. This SSD delivers sequential read speeds up to 2100 MB/s and write speeds up to 2000 MB/s, making it well suited for workloads like database exports, media ingestion, and full backups.

Its strong random IOPS performance—up to 450,000 for reads and 90,000 for writes—ensures responsiveness even under heavy mixed traffic. Built for continuous operation, the drive supports an endurance rating of one full drive write per day over five years, which helps maintain consistent throughput in write-heavy applications such as transaction logging and virtualization.
