Seagate 2TB Xbox Expansion Card If you picked up some of the great Xbox game deals in Amazon's Black Friday sale, you should also check out the retailer's Cyber Monday deals on high-capacity Seagate Storage Expansion Cards. The 2TB Seagate Expansion Card is discounted to $184.76 (was $260), and the 4TB model is down to $380 (was $500). These are the lowest prices ever offered by Amazon for either edition. Seagate's Expansion Card is also available in a 1TB edition. This one isn't an official Cyber Monday deal, but it is discounted to $121.19 (was $160). Seagate's Expansion Card is one of two officially licensed storage upgrade options for Xbox Series X|S. Western Digital makes the other one, but the WD Black C50 isn't available for as low of prices right now. The C50 512GB is $80, the 1TB is $135 (was $150), and the 2TB is $216.19 (was $230). The 1TB model was $100 during Amazon's early Black Friday sale. Seagate's Expansion Cards used to be incredibly expensive, but the arrival of the C50 led to price drops. Seagate and Western Digital Xbox Expansion Cards offer the same functionality. You simply insert the proprietary storage card into the expansion slot on the back of your console. Your Xbox will recognize the card and allow you to choose if you want to use internal storage or expansion storage as your primary install location. That's the whole installation process; these truly are plug-and-play storage solutions. Regular external hard drives can store Xbox Series X|S games, but you need to transfer them back to the console's internal drive to actually play them.
