Samsung has announced the world’s largest production SSD drive to date with a storage capacity of 30.72 terabytes jammed into a 2.5-inch storage device.
The PM1643 is aimed at enterprised-based customers looking for higher capacity without the need for older technology that uses moving parts. Samsung was able to achieve this by combining 32 1TB NAND flash sticks, each comprised of 16 stacked layers of 512Gb V-NAND chips. That’s enough space to store 5,700 HD movies (about 500 days of continuous HD content).
The Serial Attached SCSI (SAS) has sequential read and write speeds of 2,100MB/s and 1,700 MB/s, respectively. That’s just about three times faster than average consumer grade SSDs.
“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.”
Technically, Seagate takes the prize for the biggest SSD storage device ever, but their product was only for demonstration purposes and never made it to the market. Also, the setup was in a 3.5-inch housing versus 2.5 with the Samsung PM1643.
Samsung reached the new capacity and performance enhancements through several technology progressions in the design of its controller, DRAM packaging and associated software. Included in these advancements is a highly efficient controller architecture that integrates nine controllers from the previous high-capacity SSD lineup into a single package, enabling a greater amount of space within the SSD to be used for storage. The PM1643 drive also applies Through Silicon Via (TSV) technology to interconnect 8Gb DDR4 chips, creating 10 4GB TSV DRAM packages, totaling 40GB of DRAM. This marks the first time that TSV-applied DRAM has been used in an SSD.
Complementing the SSD’s hardware ingenuity is enhanced software that supports metadata protection as well as data retention and recovery from sudden power failures, and an error correction code (ECC) algorithm to ensure high reliability and minimal storage maintenance. Furthermore, 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. The PM1643 also offers a mean time between failures (MTBF) of two million hours.
Samsung has already started mass-producing this model, but also plans to offer smaller variants in different sizes, including 15.36TB, 7.68TB, 3.84TB, 1.92TB, 960GB and 800GB versions.
Unfortunately, these products will not be available at the consumer level just yet, but they indirectly are pushing for further innovation, which means that the average Joe could eventually see cheaper SSDs with much more storage capacity coming up on the horizon soon enough.
