Ultra-High Capacity SAS SSD

- Breakthrough high-performing storage density

PM1643 delivers high-value faster read speeds while improving TCO with outstanding reliability, security and endurance. It provides a powerful solution for mission-critical enterprise applications. It also provides significantly more capacity up to 30.72 TB.

Samsung PM1643 SAS SSD delivers:

• World’s Largest Storage Density: By fitting more memory cells into a V-NAND chip, the PM1643 provides significantly more capacity-up to 30.72 terabytes (TB) in a 2.5” small form factor drive; Up to 737.28 TB can be stored in a 2U server.

• Exceptional Value: Using the latest Samsung 64-layer V-NAND flash memory, the powerful TLC flash memory employed in the PM1643 can address high-end enterprise applications, outperform planar MLC flash memory, and provide reliable solid state performance.

• High Performance: The PM1643 provides over 6 times the sequential read and write performance of the fastest 15K RPM HDDs 1, respectively. It also delivers wide bandwidth of up to 2,100 MB/s for sequential read speed. Random read and write speeds reach up to 400,000 IOPS and 50,000 IOPS, respectively.

• Power Efficiency: With no moving parts, the PM1643 achieves up to 2,000 MB/s sequential write speed at 13.5W power. This equals about 148 MB/s per watt, which is 4 times more power efficient than 15K RPM HDDs and a 60% improvement from Samsung’s previous generation PM1633a SAS SSD.

• Long-lasting Reliability: Enhanced software provides metadata protection as well as data retention and recovery from sudden power failures; and an error correction code (ECC) algorithm ensures high reliability and minimal storage maintenance. Also, the PM1643 offers an endurance level of one full drive write per day over a five- year warranty period, translating to up to 30.72 TB of data written every day over five years without fail. The SSD also provides a mean time between failure (MTBF) of two million hours.

PM1643a kommer ersättas av PM1653 när den nått full produktion någon gång under 2023.
