If youve just unwrapped a new Xbox Series X or Series S for Christmas, youll have enough storage out of the box to download several games. But youll quickly feel the squeeze from 100GB-plus installs, especially if you tend to keep a heavy rotation. Expansion cards are your only relief on Xbox consoles if youre playing titles optimized for Series X/S. Thankfully, you can get a 2TB expansion card cheaper than ever, with Western Digitals WD_Black C50 going for $189.99 ($70 off) at Amazon. You can also get it in 512GB for $69.99 ($10 off) and 1TB for $109.99 ($48 off). That said, the 2TB model is the better deal in the long run.RelatedBecause the Series X and Series S use a proprietary storage format, you cant use an external SSD, an internal NVMe SSD (as you could on the PS5), or a standard external hard drive to play newer games that are optimized for those consoles. You can use those hard drives to store Series X/S games, but expansion cards like the C50 are the only ones you can actually play them from. Thats because they support the platforms velocity architecture, which has a minimum speed requirement and uses unique hardware and software tricks to enable console features like Quick Resume, not to mention other benefits for developers. Anyway, you dont need to be a computer science major to understand the bottom line: if you want more storage for your Series X/S games, youll need an expansion card.WD_Black C50 Expansion Card for Xbox Series X / S$70$8013% off$70$70$8013% offWestern Digitals storage expansion cards for Xbox Series X / S consoles are speedy, plug-and-play cards that match the performance of the consoles onboard SSDs.
