The PCI Special Interest Group (PCI-SIG) has issued a completed standard for PCI Express 6.0, laying the groundwork for SSDs that will outperform the present crop.
When compared to the PCIe 5.0 standard, the new PCIe 6.0 specification doubles raw data transfer rates from 32GT/s to 64GT/s.
With each subsequent generation, the PCI-SIG was able to retain its track record of tripling bandwidth. A single lane will be capable of 8GB/s in each direction with PCIe 6.0, scaling up to 128GB/s per direction in an x16 arrangement.
PCIe 6.0 is a standard for PCIe cards
PCIe 6.0, which was first announced in 2019, would undoubtedly open the way for SSDs with read/write speeds that far beyond those of the present market leaders.
To put things in perspective, the fastest PCIe 4.0 SSDs can read at about 7GB/s and write at around 6.5GB/s. Meanwhile, PCIe 5.0 SSDs with claimed read speeds of up to 12GB/s and write rates of 11GB/s are slated to hit the consumer market soon, and Samsung has introduced an enterprise model with read capabilities of up to 13GB/s.
This is already a level of performance that typical PC workloads do not need. However, the PCIe 6.0 advancements will open up a slew of new possibilities for businesses that depend on the processing and transport of large volumes of data.
“PCIe 6.0 technology is the most cost-effective and scalable interconnect option,” said Al Yanes, PCI-SIG Chairperson and President. “It will continue to affect data-intensive areas including data centres, artificial intelligence/machine learning, HPC, automotive, IoT, and military/aerospace.”
PCIe 6.0 will assist satisfy the insatiable need for performance enhancements across a variety of data centre industries, according to Ashish Nadkarni, Group Vice President at analysis firm IDC.
“The application ecosystem will look quite different in three to five years, and organisations will most likely begin revising their roadmaps appropriately.” “The evolution of a well-established standard like PCIe 6.0 architecture will help the industry create composable infrastructure for performance-intensive computing use cases,” he added.
The PCI-SIG anticipates the first PCIe 6.0 hardware to hit the market within the next 12-18 months, now that the standard has been completed. In actuality, this implies that the technology will enter servers in 2023 and then flow down to consumer PCs a few years later.
