PCIe 5.0, which enables much higher speeds in NAND memories, has slowly started to find its place in the first examples, but the industry, including manufacturers, is not ready for such high speeds yet. In the first place, relatively low speeds will meet us.
What are the PCIe 5.0 SSD speeds?
With PCIe 5.0 technology, speeds up to 16GBps will be possible on SSD drives, but this is of course the last point. The best SSD controllers are currently pushing 14GBps speeds, but NAND memory improvements are not as expected.

Currently, manufacturers such as Micron and SK Hynix can produce 3D NAND memory with 176 layers. This causes it to stay below 10GB/s speeds. Micron stated that its 232-layer NAND memory reached 12.4GB/s. In other words, we will see high speeds when these layers are reached at the earliest. It is stated that the Phison PS5026-E26 controller, which will be widely used, has 12GB / s write and 13GB / s read speeds.
Authorities state that it is difficult for the first PCIe 5.0 SSD models to exceed 10GB/s levels. However, it will be possible to see 10GB/s and beyond in SSD drives released in 2023. In this regard, users who are looking for a PCIe 5.0 SSD are advised to wait for a while.
