I expect as much … we’ve only just started to see PCIE Gen4x4 SSDs become more mainstream this year. It will require more than a couple of years for manufacturers to see some return and to recoup some of its investment.
Taken from TPU … Although we’ve already seen some companies both tease and announce PCIe 5.0 consumer SSDs, it seems like we shouldn’t expect mainstream PCIe 5.0 SSDs until 2024, at least if Silicon Motion’s earnings call is anything to go by. Wallace Kou, Silicon Motion’s CEO was quoted as saying “”It is likely that PCIe Gen4 will last a few years since Intel, AMD both continue to bring new upgrade variant of CPU with PCIe Gen4 to the market,” continuing “Similarly, we are preparing for the launch of our third-generation PCIe Gen4 controller next year before transitioning to PCIe Gen5 in the following year.”
This obviously has something to do not only with development time, but also with recuperating the costs of developing the previous generation of PCIe 4.0 SSD controllers before introducing new products that would have limited market share due to at least initially high prices. Silicon Motion is said to be working on multiple PCIe 5.0 SSD controllers with the enthusiast grade SM2508 expected towards the end of this year and it’s set to compete with Phison’s PS5026-E26 and InnoGrit’s IG5666 controllers, plus unannounced inhouse controllers from the likes of Samsung and WD. Silicon Motion’s mainstream PCIe 5.0 controller is said to be the SM2507, which is also said to be more suitable for mobile applications, most likely due to lower power consumption. However, the first PCIe 5.0 controller from Silicon Motion should be the SM8366 enterprise grade controller that was announced last year and which should be shipping in the second half of this year. For most users, PCIe 5.0 SSDs are unlikely to make a huge difference, unless we see some major improvements when it comes to random read and write performance, as this is currently the real bottleneck with SSDs.
