Seagate STJR1000400

Overview

The Seagate STJR1000400 is a 1TB internal NVMe SSD designed specifically as a storage expansion card for Xbox Series X and Xbox Series S consoles. It connects via the console’s dedicated expansion slot and uses a PCIe Gen 4 x2 interface to deliver speeds that match the internal drive. This ensures you get additional storage without compromising the fast load times and smooth gameplay that define the current generation of Xbox gaming.

This expansion card is perfect for gamers who frequently download large titles, update games, or maintain a sizable library of 4K-capable games. It also supports backward-compatible titles, allowing you to run original Xbox, Xbox 360, and Xbox One games directly from the card with consistent performance. Quick Resume functionality remains fully supported, enabling seamless switching between multiple games.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
