iATKOS | United Kingdom: Samsung Unveils World's Largest 2.5-inch SSD With 30.72TB of Storage

Samsung has begun mass production of the world's largest capacity Serial Attached SCSI (SAS) solid state drive (SSD) – the PM1643. With 64-layer, 3-bit 512-gigabit (Gb) chips, the 30.72 terabyte (TB) drive delivers twice the capacity and performance of the previous 15.36TB high-capacity lineup introduced in March 2016.

The larger drive was made possible by combining 32 of the new 1TB NAND flash packages, each comprised of 16 stacked layers of 512Gb V-NAND chips. 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.

In addition to the doubled capacity, performance levels have risen significantly and are nearly twice that of Samsung’s previous generation high-capacity SAS SSD. 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. These represent approximately four times the random read performance and three times the sequential read performance of a typical 2.5-inch SATA SSD.
