Using a 12Gb/s SAS interface, the PM1643 is quoted to deliver random read and write speeds of up to 400,000 IOPS and 50,000 IOPS, and sequential read and write speeds of up to 2,100MB/s and 1,700MB/s, respectively. Samsung was able to achieve this new level of capacity and performance through several technology improvements with its in-house controller, DRAM packaging, and associated software. Among these advancements is a highly-efficient controller architecture that integrates nine controllers from the previous high-capacity SSD lineup into a single package. This allows for a significant leap in capacity. Moreover, the PM1643 features Through Silicon Via (TSV) technology to interconnect 8Gb DDR4 chips, creating 10 4GB TSV DRAM packages for a huge 40GB in DRAM. The PM1643 also features enhanced software that supports metadata protection, data retention and recovery from sudden power failures as well as an error correction code (ECC) algorithm for high reliability and minimal storage maintenance.  Additionally, Samsung’s new SSD has a high endurance level of one full DWPD and offers an MTBF of two million hours. **Availability** Samsung indicates that they have started manufacturing initial quantities of the PM1643 SSDs this past January with plans to expand the lineup slated sometime later this year (i.e. 15.36TB, 7.68TB, 3.84TB, 1.92TB, 960GB and 800GB models).
