Samsung Electronics has introduced a new Solid State Drive (SSD) offering 30 terabytes (TB) of storage. Measuring a mere 2.5 inches wide the PM1643 is the largest capacity SSD in the world and intended for enterprise storage systems.
The 30TB drive is comprised of 32 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.
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.
