The 7th gen V-NAND memory chips with 176 layers from Samsung are offering the smallest cell size in the industry right now, with 16% increased energy efficiency over previous gen and 2 Gbps I/O speeds that are designed to take advantage of the PCIe 4.0 and PCIe 5.0 standards. 990-series NVMe SSDs are expected to be released towards the end of the year.

Clear you mean 2 GBps. Such a mistake is not expected from a professional writer :)

Check the Samsung source, which clearly states 2 gigabits.
It might be per cell or chip, which would make more sense since the speed varies based on capacity.

And they can't be wrong? 2 Gigabits is just 250 MB/s :) :) For a cutting edge SSD?

Yes, even per package wouldn't explain it. They would need dozens of them. Unfortunately, there are no journalists here. A journalist would inquire. And a competent one, knowledgeable about the subject he writes about, would do so before publishing in the first place. If it makes no sense to me, I can't publish it, surely.

Of course, the speed they are quoting is probably bare, without cache (caching is controller's responsibility; this isn't a complete SSD). That's going to make a big difference. Frankly, I don't know what those specifications look like for older chips. And that's exactly why I would inquire.
