Samsung Squeezes 30TB Into a 2.5-Inch SSD

Samsung's PM1643 SSD is the successor to 15.36TB series, introduced by the company in March 2016.

Spec-wise the PM1643 uses 512Gbit, 64-layer, TLC (3bits/cell) V-NAND (Samsung's 3D NAND tech) chips. Based on a 12 Gb/s Serial Attached SCSI interface, the 30.72 TB drive is reported capable of random read speeds of up to 400,000 IOPS, and 50,000 OIPS write. Sequential read rates are up to 2,100 MB/s, while sequential write rates are up to 1,700 MB/s. That's fast. Really fast.

Samsung's PM1643 drive uses Through Silicon Via (TSV) technology to interconnect 8GB DDR4 chips.

The PM1643 supports a full drive write a day for its five-year warranty period and has a a 2 million hour MTBF rating - nothing exceptional, certainly not compared to Samsung's recent 860 EVO with its boosted endurance of more than two full drive writes a day.

Though the new drive is aimed squarely at enterprise users, the storage capacity and performance improvements are likely to trickle down to consumers in the near future. These represent approximately four times the random read performance and three times the sequential read performance of a typical 2.5-inch SATA SSD*.

Meanwhile, Seagate had previously made an SSD with 60TB storage, but that was in the 3.5-inch form factor and was labeled "demonstration technology". The new drive also features a 40GB DRAM, an upgraded and more efficient drive controller and associated software.The SSD is said to be able to hold about 5700 HD movies of 5GB each which is much more than anything in the industry is able to hold. Complementing the hardware Samsung provides software for metadata protection as well as data retention and recovery from sudden power failures.

Samsung has launched the PM 1643 Solid State Drive (SSD) on Tuesday, with a capacity of 30.72 terabytes making it the world's largest SSD in terms of capacity.

It's not clear when the PM1643 will go on sale, but Samsung said it started manufacturing initial quantities in January 2018 and has plans to expand the range throughout the year with 15.36TB, 7.68TB, 3.84TB, 1.92TB, 960GB and 800GB versions.

Jaesoo Han, executive vice president of Samsung's Memory Sales and Marketing Team commented that, "Samsung will continue to move aggressively in meeting the shifting demand toward SSDs over 10TB", which is good news for everyone.
