I’m convinced Best Buy doesn’t know this Seagate Xbox Storage Card deal is still live — and I’m not telling if you won’t
Prime Day is over, but the discount on the 4TB expansion card from Seagate remains.

With the latest Xbox Series X and Xbox Series S games getting larger and larger, the Seagate Xbox Storage Expansion Card is a must-have accessory. Prime Day may be over, but you can still save on the card.
The 4TB Seagate Xbox Storage Expansion Card is still on sale for $429.99 at Best Buy. Because of its discounted price, the 4TB model delivers the most storage per dollar.
Other models of the card are still discounted, but the prices are not nearly as low as we saw for Prime Day.
"When looking for a seamless storage expansion for your Xbox, eliminating the need to manage storage, the Seagate Storage Expansion Card is unbeaten. There's nothing else that compares, with little to fault, beyond the high asking price. They are frequently on sale, though, so keep an eye out during Black Friday or Amazon Prime Day to grab it a bit cheaper." — Jez Corden
✅Perfect for: Those who want the most storage possible for their Xbox Series X|S.
❌Avoid if: You do not need 4TB of additional storage or are on a budget. Even while discounted, this card is expensive.

Best Xbox Series X|S accessory
The best Xbox Series X|S accessory is a device you'll plug in once and then likely never look at again. Seagate's card adds up to 4TB of additional storage to your console.
Importantly, the drive has the same speeds as the internal storage of the Xbox Series X and Xbox Series S, meaning you won't have to deal with any additional loading times. The speed of the card also means modern games can be played directly off the card.
Xbox Series X|S optimized games cannot be played using standard USB drives, which makes one of these expansion cards an essential accessory for your console.
The card is the best SSD for an Xbox Series X|S. It's easy to use, quick, and has a proven track record.
In our Seagate Storage Expansion Card review, we called the device "an almost-perfect solution that seamlessly expands your Xbox console."
An expensive upgrade
In terms of design and performance, Seagate's solution is practically perfect. It's sleek, quick, and installation is simple.
The biggest drawback of the card has always been its price. Heck, the retail price of the 4TB model is the same as the cost of an Xbox Series X until recent global price increases.
Discounts on the card happen often, so it's hard to recommend the accessory at full price. Fortunately, the cards go on sale frequently.
Also, Best Buy has extended its launch-day price for the 4TB Seagate Xbox Storage Expansion Card.

The 1TB and 2TB versions of the card have dropped in price since the beginning of the July shopping period.
