We now see widespread support only for PCIe 5.0, but as is often the case in this industry, it is old technology at the time of the arrival of new technology. And so, PCI Special Interest Group today released a final spec for PCI Express 6.0, laying the groundwork for the next (next?) Generation of SSDs.

Let’s get up to speed right, what do we do? This next version doubles the raw data transfer speeds from 32 Gigabytes per second (GT / s) on PCIe 5.0 to 64GT / s on PCIe 6.0 and up to 8. GB / sec on each side or 256 GB / s in x16 configuration.

Now that the final version of the specification has been approved, the consortium is hoping We will see the first commercial product come on the market in the next 12 to 18 months, which means Sometime in 2023. Note “Commercial” —these ultra-fast storage devices will find their way to the server before you view the PCIe 6.0 SSD on a consumer product. The PCI Special Interest Group says the “primary target applications” for the technology include AI and machine learning, networking and storage in the data center, industrial, automotive and military.

That timeline is similar to what we saw with PCIe 5.0; The current standard was finalized in 2019, but Samsung and Adata teased the first PCI 5.0 SSDs in the buildup of CES 2022 a few weeks ago, and they are aimed at enterprise customers. It’s also worth noting that when Intel’s 12th-gDesktop chip support PCIe 5.0, the new mobile processor of PCIe Gen 4 is limited, a decision Intel said was made to keep Gizmodo costs low, and because no PCIe Gen 5 card was available for validation.

The new standard is a significant achievement for the PCI Special Interest Group, which has reached the goal of doubling the speed of PCI Express every three years since SPEC started in 2003. In this case, it did so using a completely different signaling technology called PAM4 (Pulse). Amplitude modulation with 4 layers).

I will not bombard you with technical details (those who are interested can know more Here), But people at Anandtech Say change is “Undoubtedly the greatest in the history of the standard.” And it doesn’t just enable fast speeds, But it also enables low latency operations.

When it arrives, PCIe 6.0 will lag behind-Compatible with existing hardware, so PCIe 5.0 or earlier components will work just fine when connected to a PCIe 6.0 host, and vice versa.

The new standard is designed to deal with the growing number of applications that require high-bandwidth, low-latency data transfer. Commercial markets have a greater need and budgets to be the primary adopters of PCIe 6.0, but eventually, the value will find its way into consumer products like graphics cards and SSDs – just in time, I’m sure, for PCIe 7.0.
