Samsung's new 30TB SSD is the largest in the world


Two years ago, Samsung unveiled a massive 15.36TB SSD and now it has doubled that storage in a single drive – the PM1643.

Billed as the world's largest capacity Serial Attached SCSI SSD, the PM1643 has now entered mass production.

The PM1643, as it's called, is built from 32 sticks of 1TB NAND flash packages, each of which contains 16 layers of 512Gb V-NAND chips. So in layman's terms space is enough to have nearly 5,700 HD movies or approximately 500 days of non-stop video. It features lightning-fast data transfer speeds as well.

Samsung claims the PM1643 reaches 2,100/1,700 MB/s of sequential read/write throughput and up to 400,000/50,000 read/write IOPS. Instead, Samsung expects it to be a hit among enterprise customers, wanting to pack as much memory - and fast memory, at that - into as small a footprint as possible. The figures are around four times the random read performance and three times the sequential read performance of a typical 2.5-inch SATA SSD.

Though the new drive is aimed squarely at enterprise users, the storage capacity and performance improvements are likely to trickle down to consumers in the near future. Among these advancements is a highly-efficient controller architecture that integrates nine controllers from the previous high-capacity SSD lineup into a single package. The drive also includes 40GB of DRAM thanks to Through Silicon Via (TSV), which allows for the interconnection of 8Gb DDR4 chips.

The PM1643 also features enhanced software that supports metadata protection, data retention and recovery from sudden power failures as well as an error correction code (ECC) algorithm for high reliability and minimal storage maintenance. Samsung, which is now leading the flash-based storage market, has announced a whopping 30.72TB SSD. "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. Like its other capacious counterparts, the drive comes in a 2.5" form factor with a 15mm thickness, which means it will not fit in your laptop. The company plans to add 15.36, 7.68, 3.82, and 1.92TB options.
