Xbox Series X Storage Expansion Card revealed, promises performance match with internal SSD
We now finally know some concrete details on what's going to happen with that storage expansion slot on the back of the Xbox Series X.
What you need to know
- The Xbox Series X Storage Expansion Card will hook up to the slot on the rear of the console.
- Promises identical performance to the internal SSD.
- 1TB custom solution built in partnership with Seagate.
As part of the massive data dump on the Xbox Series X the mystery of the storage expansion slot on the rear has been made a little clearer. The slot will be used for the Xbox Series X Storage Expansion Card (yes, what a mouthful), a custom storage solution built in partnership with Seagate.
Inside the console, we'll be getting a 1TB NVMe SSD for storage, but given how big games are going to get in the next-gen, this won't go very far. So, Microsoft has designed a solution to expand that without the necessity to go inside the console and start fiddling with things we shouldn't really be fiddling with. For now Microsoft has only officially confirmed a 1TB Storage Expansion Card, but apparently larger sizes should be coming in future.
It's not a replacement for external USB hard drives, as those will continue to be supported, but the Storage Expansion Card is promising identical performance to the internal drive, as this outline from Microsoft indicates, recommending that Series X optimized games aren't played from a USB hard drive for optimal performance.
And as the Digital Foundry team points out, the Xbox Series X utilizes PCIe 4.0 to connect both the internal and external SSD storage directly to the CPU. So far we've only seen PCIe 4.0 used on AMD's X570 platform on PC, but the data speeds it's capable of are pretty spectacular so we're excited to see Microsoft make use of it in the Series X.
