Samsung Electronics announced mass production of t the industry’s largest capacity Serial Attached SCSI (SAS) solid state drive (SSD) to date – the 30.72 terabyte (TB).
The new PM1643 drive uses Samsung's latest V-NAND technology with 64-layer, 3-bit 512-gigabit (Gb) chips. It offers twice the capacity and performance of the previous 15.36TB high-capacity lineup introduced in March 2016.
Samsung said the density is 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.
Based on a 12Gb/s SAS interface, the new 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.
"With our launch of the 30.72TB SSD, we are once again shattering the enterprise storage capacity barrier, and in the process, opening up new horizons for ultra-high capacity storage systems worldwide," said Jaesoo Han, executive vice president, Memory Sales & Marketing Team at Samsung Electronics. "Samsung will continue to move aggressively in meeting the shifting demand toward SSDs over 10TB and at the same time, accelerating adoption of our trail-blazing storage solutions in a new age of enterprise systems."
