Although it of course won't move at these speeds, it does feature sequential read and write speeds of up to 2,100MB/s and 1,700 MB/s (random read and write speeds of up to 400,000 IOPS and 50,000 IOPS), matching it to speeds similar to NVMe SSD options and so much quicker than SATA.
Along with being big and fast, the world's largest SSD is robust as well. It delivers almost twice the capacity and performance of the previous generation. The official press release mentions the following capacities: 15.36 TB, 7.68 TB, 3.84 TB, 1.92 TB, 960 GB, and 800 GB.
The drive uses a 12Gb/s Serial Attached SCSI interface. New NVMe SSDs have similar features via the latest versions of the specification, but we have yet to see such voluminous capacities in the performance-focused NVMe realm.
Samsung was able to create this SSD by combining 32 1TB NAND flash packages, each comprised of 16 stacked layers of 512Gb V-NAND chips. It is all packed into the typical 2.5-inch SSD drive style (and about twice the height of a 2.5-inch solution you'd find in a laptop).
As with any fast SSD, the PM1643 comes with plenty of DRAM to help speed up internal operations.
In the realm of the consumer-focused SSDs we normally cover around these parts, a capacity of 2 TB is generally considered to be pretty large. The drive's four 10 GB TSV packages are built from interconnected 8 Gb DDR4 chips. This type of distributed architecture is common in high-capacity SAS SSDs, such as Seagate's SAS SSDs that use eASIC bridges. An error correction code algorithm is incorporated to ensure reliability and minimal storage maintenance. Samsung's Jaesoo Han, who leads the company's Memory Sales & Marketing Team boasted that the new SSD will open new horizons for compact super-high capacity storage technology across the world. Spinny metal hard drive capacities top out in the mid-teens these days. These drives are destined for OEM systems, so pricing likely hinges on volume purchasing agreements.
Imagine how many games from your Steam library you could install if you had a 30TB solid state drive.
