Early shipments of PCIe 4.0 SSDs delivered impressive performance with super fast data read and write speeds, but PCIe SSDs also cost a fortune compared to PCIe 3.0 SSDs. That could all change, however, with Silicon Motion announcing three new PCIe 4.0 controllers. This could lead to a hotter competition over the price and quality of SSDs, which will certainly be good news for users. For everyone to understand, the controller chip is basically a processor that manages the NAND flash memory chips on SSDs, and it is directly related to the performance of the drive.
Silicon Motion has announced the release of three PCIe 4.0 controllers, of which only one SM2264 is geared toward performance improvements. SM2264 supports sequential read speeds up to 7,400MB / s and sequential write speeds up to 6,800MB / s. It will compete with Phison’s E18 controller, which supports read and write speeds of up to 7,000MB / s, along with the own manufactured controllers that some companies like Samsung are using.
The remaining two Silicon Motion controllers aren’t as impressive as the SM2264. These include SM2267 for entry-level SSDs and SM2267XT, which are DRAM-free versions aimed at the mainstream market. Both support read and write speeds up to 3,900MB / s and 3,500MB / s respectively. Despite being the new PCIe 4.0 versions of their data read and write speeds are on par with high-end PCIe 3.0 SSDs on the market.
All the speed specs of the PCIe 4.0 models are theoretical, but it may not be long before both Microsoft and Sony will adopt the high-speed PCIe 4.0 SSD solutions on Xbox Series X models and Their PlayStation 5, each solution promises to deliver better load times and processing speeds as well as facilitate a more expansive game world.
Put simply, SSDs for next-generation consoles can change the writing of a game, which is improving bit by bit on the PC platform. To achieve this goal, Microsoft recently released the DirectStorage API for Windows 10, based on the same Velocity architecture that powers the Xbox Series X’s storage subsystems.
So on the surface, Silicon Motion’s announcement doesn’t seem important. But looking at things broader, the potential for less expensive PCIe 4.0 SSDs along with developers focusing more on high-speed storage is huge.
