World’s Largest 30TB SSD In A 2.5″ Form Factor Unleashed!


Samsung has announced the world’s largest capacity Serial Attached SCSI (SAS) solid state drive (SSD) – the PM1643 – for enterprise storage systems. The SSD sports a capacity of 30.72 terabytes which is enough to store 5,700, 5GB full HD movies, in a 2.5-inch form factor.

The SSD combines 32 1TB NAND flash packages, each comprised of 16 stacked layers of 512Gb V-NAND chips.

It claims twice the capacity and performance of the company’s previous 15.36TB high-capacity lineup introduced in March 2016.


Using a 12Gb/s SAS interface, the new SSD boasts 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.

“These represent approximately four times the random read performance and three times the sequential read performance of a typical 2.5-inch SATA SSD”, Samsung said.

Enhanced software supports 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.

In addition, the SSD provides a robust endurance level of one full drive write per day (DWPD), which translates into writing 30.72TB of data every day over the five-year warranty period without failure.

Mean time between failures (MTBF) is two million hours.

Samsung started manufacturing initial quantities of the 30.72TB SSDs in January and plans to expand the lineup later this year – with 15.36TB, 7.68TB, 3.84TB, 1.92TB, 960GB and 800GB versions – to further drive the growth of all-flash-arrays and accelerate the transition from hard disk drives (HDDs) to SSDs in the enterprise market.
