Blazing fast PCIe 5.0 SSD prototype hits sequential read speeds of 14,000 MB/s:
Advancements in the storage segment are the unsung heroes in today's world of computing. While many users tend to focus on the speed of their CPU, GPU or even the higher refresh rate of their displays, the increasingly quick solid state drives are in part responsible for the performance improvements of Sony's and Microsoft's next-gen consoles. But while the PlayStation 5 and Xbox Series X/S rely on PCIe 4.0 SSDs, a Japanese memory manufacturer is already finalizing the development of its blazing fast PCIe 5.0 storage solutions.
In a recent presentation, Kioxia has now revealed how quick PCIe 5.0 SSDs can truly be. While the throughput of the PCIe 5.0 interface at 32GB/s per lane is exactly twice as high compared to PCIe 4.0, the company's first prototype has apparently reached sequential read speeds as high as 14,000MB/s. That is also twice as fast as Kioxia's currently top of the line PCIe 4.0 drive.
Even though these read speeds certainly seem impressive, the write speeds of Kioxia's PCIe 5.0 SSD are similarly spectacular. The official benchmark says the drive can reach sequential write speeds of 7,000MB/s, which is a 67% improvement to the predecessor. Overall, these speeds seem to be absolute overkill for most use cases, which is why these drives are intended for use in a professional server setting. Nevertheless, the rapid advancements in storage speeds certainly deserve more attention than the often incremental upgrades in the CPU and GPU sector.
Of course, there's more to storage than speed, there's reliability, for example. Would any gamers want to prove the "professional server setting" assumption wrong?

The question to ask is, then, what write speed the drive can SUSTAIN once its fast buffer is used up?
The peak value in a contrived setting means nothing at all. A drive in a real-world system must handle real-world loads, and be fast doing THAT.

I'm more curious about speed comparisons to the other components on a typical PC motherboard. I mean if the SSD blows past memory and/or CPU speeds, wouldn't it mean current PC architecture [anandtech.com] could start to bottleneck performance?

Well, now you might need a bigger heat sink for the SSD than the CPU..

I guess it could mean that swapping gets far more attractive, as now your computer won't slow down to a crawl due to disk I/O.
Note that the slowest DDR4 speed [crucial.com] is 19200 MB/s, which is in the same ballpark but still faster than the quoted SSD read speed. and about 2.5 times the quoted SSD write speed. The SSD would outperform DDR3 memory, but I guess if you invest the money to buy this disk, you'll not settle for DDR3 memory.
The Tao of math: The numbers you can count are not the real numbers.

You get a point from me, AC, because that was my first thought. We just had an article a few weeks ago (too lazy to look it up) where the companies are playing around with speed numbers and under delivering in the real world.
