Microsoft and Seagate have announced a couple more SSD expansion cards for the Xbox Series X/S, both of which will be launching in the coming weeks. There’s the 512 GB card, which will launch in mid-November and will cost $139.99. Meanwhile, a 2 TB expansion card will be launching in early December, and will set you back $399.99. In comparison, the 1 TB card that’s been available since last year costs $219.99.

Seagate’s Xbox Series X/S storage expansion cards are the only ones on the market right now that support the consoles’ Velocity Architecture, which means that they’re the only cards that are compatible with native Xbox Series X/S games.

The PS5 recently enabled SSD expansions, with various manufacturers already supporting the console, including Seagate, Western Digital, and Gigabyte.

Seagate announced the FireCuda 530 PCIe Gen4 NVMe SSD recently, which is going to be launching very soon, and speaking with Finder, they confirmed that the SSD will indeed be compatible with the PS5’s SSD expansion slot, as some have predicted. Both versions of the SSD – with and without the heatsink – will be compatible.

So far, the only external SSD to support the Xbox Series X/S has also been made by Seagate.

The FireCuda 530 NVMe SSD will come with four options- 500 GB, 1 TB, 2 TB, and 4 TB, costing $140, $240, $490, and $950 respectively. If you get the heatsink models though, the price is kicked up to $160, $260, $540, and $990 respectively. So yeah, you’re going to have to cough up a ridiculous amount of money for one of these when they launch in August.

Microsoft confirmed in its full reveal of the Xbox Series X’s specifications that it would have a port for adding a 1 TB expansion card. This would match the console’s own 1 TB NVMe SSD but that’s not all. In a blog post covering various technology terms for the console, Microsoft revealed that this solution was created in partnership with Seagate.

USB 3.2 external hard disk drives can still be attached to the console but it’s advised to natively install Xbox Series X titles onto the NVMe SSD or the expansion card. This is in order “to receive all the benefits of the Xbox Velocity Architecture and optimal performance” that the console provides. Pricing for these expansion cards remains to be seen but they likely won’t be cheap.

Among other details that Microsoft revealed today about the Xbox Series X include Gears 5 supporting Smart Delivery (and only taking two weeks to run on the console). We also got a look at how Quick Resume works along with a comparison of loading times between the Xbox Series X and Xbox One X. If that weren’t enough, the console is capable of adding HDR to backwards compatible games that didn’t originally support it like Halo 5: Guardians and Fusion Frenzy.
