Samsung launches 800GB Z-SSD
It has been on its way for a while, but now it’s here. Samsung announces the launch of an 800GB Z-SSD. The new SZ985 Z-SSD is one of the most advanced SSDs to date, but it isn’t for the home-user. The drive will power HPC and AI applications. Ultra-low latency and a high reliability are key factors here.
“With our leading-edge 800GB Z-SSD, we expect to contribute significantly to market introductions of next-generation supercomputing systems in the near future, enabling improved IT investment efficiency and exceptional performance,” said Jinman Han, senior vice president, Memory Product Planning & Application Engineering at Samsung Electronics. “We will continue to develop next-generation Z-SSDs with higher density and greater product competitiveness, in order to lead the industry in accelerating growth of the premium SSD market.”
Which Capacity Is for Me?
Besides this new 800GB version, there’s also a 240GB version. The difference is clear and it comes down to how much storage you need and how you’re going to utilise the drive. It is a highly efficient storage solution for high-speed cache data and log data processing and other enterprise storage applications.
What’s the Performance?
The new single port, four-lane Z-SSD features Z-NAND chips that provide 10 times higher cell read performance when compared with 3-bit V-NAND chips. Along with the NAND are 1.5GB LPDDR4 DRAM and a high-performance controller.
You can expect a random read performance of up to 750K which puts it in a category with Intel and Micron’s 3D XPoint NAND. However, the write performance isn’t nearly the same. The Samsung Z-SSD can deliver a random write speed of up to 170K IOPS. Now that isn’t bad at all, but it isn’t near 3D XPoint. With a write latency of just 16 microseconds, the Z-SSD won’t have to search for long either.
How Long Will It Last?
Due to its high reliability, the 800GB Z-SSD guarantees up to 30 drive writes per day (DWPD) for five years. Now that’s a lot. In other words, it would be a total of 42 petabytes. That translates into storing a total of about 8.4 million 5GB-equivalent full-HD movies during a five-year period. The reliability of the new Z-SSD is further underscored by a mean time between failures (MTBF) of two million hours.

11 months ago was when we heard about the Z-SSD and we got excited. For reference, here’s the original video.
What Will It Cost?
Samsung didn’t reveal a price at this time.
