NVMe Gen4 SSD
Aside from the console’s design and connection options, new details about Microsoft’s next-gen SSD have allegedly also found its way online. Earlier this month, Taiwan-based outlet Digitimes reported that the SSD inside the Series X will be powered by a Phison controller. Based on the performance goals of Microsoft’s next-gen console, Tom’s Hardware concluded that Microsoft is most likely opting for a PCIe 4.0 variant of this controller. According to a freshly surfaced Linkedin job description from an ex- Phison software engineer, the Series X will indeed be using a Phison controller for the console’s NVMe Gen4 SSD.
Based on the Phison product number (PS5019-E19T) that has been provided and its datasheet, the NVMe SSD inside the Series X will be fast, very fast, with reading speeds up to 3.6GB/s and write speeds up to 2.2GB/s max. The maximum capacity for the controller appears to be limited to 2TB.Phison announced the arrival of this particular controller, PS5019-E19T, back in August of last year. “There is continued pressure in the industry to improve the performance of computing systems to support the applications that end users are most interested in. PCIe 4.0 offers manufacturers a way to meet these consumer demands,” said Chris Kilburn, corporate vice president, and general manager, Client Channel, AMD. “AMD is delighted to work with Phison to raise the bar by introducing first-to-market solutions. Through sound engineering and design, we are working together to deliver the experiences our customers demand.”
