Samsung Electronics Co., Ltd., the world leader in advanced memory technology, today announced that it has begun mass producing the industry's largest capacity Serial Attached SCSI (SAS) solid state drive (SSD) - the PM1643 - for use in next-generation enterprise storage systems. Leveraging Samsung's latest V-NAND technology with 64-layer, 3-bit 512-gigabit (Gb) chips, the 30.72 terabyte (TB) drive delivers twice the capacity and performance of the previous 15.36 TB high-capacity lineup introduced in March 2016.

This breakthrough was made possible by combining 32 of the new 1TB NAND flash packages, each comprised of 16 stacked layers of 512 Gb V-NAND chips. These super-dense 1 TB 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 12 Gb/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 2,100 MB/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."
