The ThinkSystem PM1645a Mainstream SAS 12Gb solid-state drives (SSDs) in capacities of up to 6.4 TB are next-generation high-performance SSDs suitable for a wide range of applications of running on ThinkSystem servers.

The PM1645a SSDs are the follow-on to the PM1645 SSDs and offer improved random write performance.

Unlike SATA drives, the 12 Gb/s SAS interface on these drives supports full duplex data transfer for higher performance, and enterprise-level error recovery for better availability. By combining the enhanced reliability of Samsung NAND flash memory silicon with NAND Flash management technologies, PM1645a SSDs deliver the extended endurance of up to 3 drive writes per day (DWPD) for 5 years, which is suitable for many enterprise applications.
