Samsung has 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, three-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.
This breakthrough 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 five-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.
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 an 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.
