Samsung begins mass production of its largest capacity solid-state drive packing 30.72 Terabytes of data storage using the latest 512Gb V-NAND flash package – the Samsung PM1643 Enterprise-Class SSD. Creating a 30.72TB SSD was possible by stacking 16 layers of V-NAND 64-layer, 3-bit 512-gigabit chips to form the new 1TB NAND Flash package wherein the SSD sports 32 of them. These super-dense 1TB packages allow for approximately 5,700 5-gigabyte (GB), full HD movie files to be stored within a mere 2.5-inch storage device.

Performance Improvement

Aside from the record-breaking capacity, the Samsung PM1643 30.72TB SSD’s 12Gb/s SAS interface yields blistering sequential read speeds of up to 2100MB/s and sequential write speeds of up to 1700MB/s. The Samsung PM1643 drive features random read and write speeds of up to 400,000 IOPS and 50,000 IOPS. The PM1643 offers performance three times that of a typical 2.5-inch SATA solid-state drive.

Latest Technologies

The Samsung PM1643 also features a new controller and custom software. The drive also utilizes Through Silicon Via (TSV) technology to interconnect 8Gb DDR4 chips, creating 10 4GB TSV DRAM packages, totalling 40GB of DRAM. The PM1643 is the first SSD to use TSV-applied DRAM. The improved software supports metadata protection along with data retention and recovery from sudden power failures. It also supports an error correction code (ECC) algorithm to ensure high reliability and minimal storage maintenance.

Endurance

The PM1643 features a robust endurance level of one full drive write per day (DWPD) which equates to 30.72TB of written data every day over the five-year warranty period. The SSD offers an MTBF of two million hours.

Availability and Capacity

Samsung began its production of the 30.72TB SSDs in January and plans to expand the line-up later this year – with 15.36TB, 7.68TB, 3.84TB, 1.92TB, 960GB and 800GB versions.
