The device uses 32 of the company's 1TB NAND packages, with each consisting of 16 stacked layers of 512Gb V-NAND chips. Besides being capacious, it's also speedy, with 2,100MB/s and 1,700 MB/s sequential read and write speeds, respectively. That's fast. Really fast.
In addition, the PM1643 can store up to 5,700 full HD videos, with an average size of 5GB per video.
Furthermore, this 30 TB SSD features TSV technology to connect 8Gb DDR4 chips which result in 10 packages of 4GB TSV DRAM. Speaking of integrity, Samsung has assured users that it has a robust endurance level of one full drive write per day which means that it is able to write the full 30.72TB of data on to the drive every day for as long as its 5-year warranty period.
Last month, we selected Samsung's 500GB 960 Evo as the best SSD for gaming due to its excellent performance and good price per gigabyte (for an NVMe drive).
Playing with envelope-back numbers we could imagine a 40TB drive with QLC flash used instead of the PMC1643's TLC, and an up to 60TB drive, far-fetched maybe, with 96-layer 3D NAND.
Samsung blows its own controller software trumpet, saying the PM1643 "supports metadata protection as well as data retention and recovery from sudden power failures, and an error correction code (ECC) algorithm" but it doesn't mention encryption which might be thought a useful feature. The record-breaking drive is the industry's largest SAS SSD; indeed, even its 40 GB of DRAM alone is more flash than some smartphones and tablets are shipping with in storage today.
To accelerate the transition in the enterprise market from HDDs (hard disk drives) to SSDs, the Korean firm plans to come up with 15.36TB, 7.68TB, 3.84TB, 1.92TB, 960GB and 800GB versions as well.
