PCIe Gen5 is coming along at a rapid pace, we should see it in enterprise systems next year. From a storage perspective, this means a theoretical doubling of performance again. The data rate specification for PCIe Gen5 at 32Gb/s is twice the lane speed of PCIe Gen4 at 16Gb/s. How that manifests still remains to be seen, the SSDs that leverage PCIe Gen5 will need to be designed well. Perhaps the most important component of these SSDs will be the controller. As with Gen4, Phison is the first to announce their SSD controller for Gen5 SSDs, the Phison E26.
