Some well-known SSD manufacturers have unveiled their new storage drives based on the PCI Express 5.0 interface over the past few weeks, which will provide twice the bandwidth of the previous PCI Express 4.0, allowing you to reach speeds previously unattainable.
However, taking a look at the data sheet, we can see that the Corsair and Goodram models, for example, indicate a maximum sequential read speed of 10GB / s, while Gigabyte reaches up to 12.4GB / s, while all using the same controller (Phison E26). As we explained in our previous dedicated article, the Phison E26 controller uses ARM Cortex-R5 cores accompanied by special accelerators that are part of the CoXProcessor 2.0 package. The chip supports all modern and future types of 3D NAND memories with ONFI 5.x and Toggle 5.x interfaces with a data transfer rate of up to 2400MT / s.

This is why which led Corsair and Goodram to indicate a speed of 10GB / s in sequential reading, as they will use 3D NAND memories at 1,600MT / s, while Gigabyte has decided to aim for the maximum possible performance with its Aorus Gen5 1000 SSD, despite currently 3D NAND chips capable of delivering 2,400MT / s are quite scarce.
