Samsung today announced that they have started the mass production of ‘PM1643’ SSD which has the industry’s largest capacity of 30.72 TB. This SSD is built on the latest V-NAND technology with 64-layer, 3-bit 512-gigabit (Gb) chips. Samsung claims that this 30.72 terabyte (TB) drive delivers twice the capacity and performance of the previous 15.36TB high-capacity SSD introduced in 2016.
This breakthrough was made possible by combining 32 of the new 1TB NAND flash packages, each comprised of 16 stacked layers of 512Gb V-NAND chips.
In addition the huge capacity, 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. The PM1643 drive also applies Through Silicon Via (TSV) technology to interconnect 8Gb DDR4 chips, creating 10 4GB TSV DRAM packages, totaling 40GB of DRAM.
Samsung is planning to expand this SSD lineup with 15.36TB, 7.68TB, 3.84TB, 1.92TB, 960GB and 800GB versions later this year.
