No doubt the speed is real but nobody will be able to achieve this speed under normal circumstances.

1. You need to read a very big file (eg 100-200GB in size) to be able to hit this speed. Thats assuming you have enough RAM so the whole file can be stored in RAM with no swapping needed.

2. If you are transferring this file to another drive, the destination will have to be the same speed too. You won't because all end-user boards will have only 1 x PCIE 5.0 nvme slot (the rest will be PCIE 4.0). Of course, you can purchase PCIE 5.0 cards to house multiple nvme drives but thats another story.

3. 10GB/s write speed is ONLY to SLC cache. Once SLC cache runs out, it will drop to usualy less than 1/2 the speed.
