Samsung introduces world’s largest capacity 30.72TB SSD for enterprise systems
Samsung has introduced world’s largest 30.72 terabyte (TB) solid state drive (SSD), PM1643 for use in enterprise storage systems. It comes in a 2.5-inch form factor, and leverages Samsung’s latest V-NAND technology with 64-layer, 3-bit 512-gigabit (Gb) chips. It introduced 15.36 terabyte (TB) solid state drive (SSD), PM1633 back in 2016. Highlights of Samsung PM1643 30.72TB SSD Enabled by combining 32 of the new 1TB NAND flash packages, each comprised of 16 stacked layers of 512Gb V-NAND chips Based on a 12Gb/s SAS interface, the new PM1643 drive features 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 1,700 MB/s, respectively. Integrates nine controllers from the previous high-capacity SSD lineup into a single package, enabling a greater amount of space within the SSD to be used for storage The PM1643 drive applies Through Silicon Via (TSV) technology to interconnect 8Gb DDR4 chips, creating 10 4GB TSV DRAM packages, totaling 40GB of DRAM. This marks the first time that TSV-applied DRAM has been used in an SSD. Enhanced software supports metadata protection as well as data retention and recovery from sudden power failures, and an error correction code ...
