The successor to last year's 15.36TB enterprise PM1633a SSD, the PM1643 is comprised of 32 1TB NAND flash packages, each made up of 16 stacked layers of 512Gb vertical NAND chips. Not anymore. Soon, you'll be able to buy a single 2.5-inch SSD and store roughly 5,700 HD movies on it. When compared to the previous generation SAS SSDs, the new drive delivered almost twice the performance.

Samsung announced the production of the PM1643, a 30.72TB SSD. The PM1643 is said to deliver twice the capacity and performance of the company's previous-generation SAS SSD. The drive has a 12GBps SAS interface with random read and write speeds of up to 400,000 IOPS (Input/output operations per second) and 50,000 IOPS as well as sequential read and write speeds of up to 2,100MBps and 1,700MBps, respectively. Now this year, Samsung is taking it a step further with the new "PM1643", a 30TB SSD built on the latest 512Gb V-NAND. Sequential read rates are up to 2,100 MB/s, while sequential write rates are up to 1,700 MB/s.

In the last decade, Liverpool and Tottenham both have one silverware each to their name - the League Cup or as we now call it, the Carabao Cup.

According to Samsung, the new drive performs approximately four times better than a typical SATA SSD; as these drives are focussed on the enterprise, the company also noted that they offer a mean time between failures (MTBF) of two million hours.

With this SSD, Samsung is debuting a new controller architecture that integrates nine controllers into a single package, enabling a greater amount of space within the SSD form factor to be used for storage. The drive also has Through Silicon Via (TSV) technology to interconnect 8GB DDR4 chips, creating 10 4GB TSV DRAM packages (totaling 40GB). It should be noted that this is the first time that Samsung used TSV-applied DRAM in an SSD. Complementing the hardware Samsung provides software for metadata protection as well as data retention and recovery from sudden power failures. That's created to give better data retention and recovery rates after sudden power failures, and an error correction code (ECC) algorithm for less storage maintenance. The SSD comes with an endurance level of one full drive write per day (DWPD) that makes it a ideal option to write 30.72TB of data every single day over the five-year warranty period.
