Intel Shows Huge Performance Of PCIe 5.0 SSDs

PCIe 5.0 SSDs are one of the new standards that will arrive in 2022 after the launch of new features such as DDR5 memories, the deployment of Wi-Fi 6E and other next-generation standards that are expected for the new year such as USB4.

Intel planned to conduct a series of live technology demos, complementing the inaugural conference of the CES that will be given by its CEO, Gregory Bryant. The mutation of the ‘bug’ and its high degree of contagion that has us in suspense for two years now, has caused cancellations of physical presence and it seems that Intel (and others) will only make product presentations virtually.

One of the planned demonstrations was that of the PCIe 5.0 SSD. It won’t be produced at CES, but Ryan Shrout, Intel’s Chief Performance Officer, shared the results with us at Twitter:

The proof is about a direct comparison between PCIe 4.0 and the next generation of the interface, 5.0. And specifically, a WD Black PCIe 4.0 (which we analyze here) and a Samsung PCIe 5.0 which for the occasion was the PM1743 business model since for now there are no consumer versions for sale.

The test was carried out on an Alder Lake platform with a Core i9-12900K processor and the results were as expected. If the WD 4.0 (among the best in its segment) offers a performance in sequential read of 7 GB / s, the Samsung drive connected to PCIe 5.0 exceeded 13 Gbytes per second, almost double.

To make the test even more interesting, Shrout installed two Samsung SSDs in RAID to achieve 28 GB / s, a stratospheric brand for the consumer market. However, due to the limited number of PCIe 5.0 lanes on the Alder Lake board, he had to remove the dedicated graphics so that the solid state drives could achieve maximum performance.

It is only a demonstration, but it anticipates what is to come once the manufacturers commercialize the PCIe 5.0 SSDs, which Intel already supports in Alder Lake and which AMD will also do with the new Ryzen. It is clear that the SSD have broken with the traditional bottleneck of hard drives and opened a new arena for internal storage. We especially recommend them for any PC update. Even if it is with a SATA model, you will notice it a lot.
