SanDisk expansion cards for Xbox Series X|S now available on Amazon — alternative storage solution to Seagate, WD arrives on the market five years after the launch of the consoles
An alternative storage solution for the Xbox Series X|S finally arrived on the market five years after its launch. The SanDisk Optimus GX C50 starts at 1TB on Amazon and costs $249.99, while the 2TB version will set you back $486.99. SanDisk initially announced the Optimus SSD lineup in early January 2026, but it only revealed this storage solution for the Xbox Series X|S in August of this year. These drives are also listed at a discount directly on the SanDisk website, with the 512GB available for just $109.99, and the 1TB and 2TB versions priced at $199.99 and $339.99, respectively. However, they’re all listed as unavailable at the time of writing, meaning you’ll have to be patient and click on ‘Notify Me’ to get informed once stock becomes available.

Seagate was the only brand to offer a storage expansion card for the Xbox Series X|S at launch, with the Seagate Storage Expansion Card for Xbox Series X|S, initially available at a 1TB capacity with an SRP of $199.99. Unfortunately, the AI-driven memory and storage chip shortage has caused NAND prices to balloon, meaning the cheapest brand-new options from third-party sellers on Amazon now start at $318. The brand followed this up with 2TB and 4TB options, with an SRP of $299.99 and $549.99, respectively, but Amazon pricing has brought the former up to $473.99 while the latter remains unavailable.
The Xbox Series X|S launched in 2020, meaning it has been more than six years since these consoles arrived on the market. Despite that, Seagate and SanDisk are your only options if you want to play games directly off the add-on storage slot. Western Digital also used to make these add-on cards for the Xbox, but its decision to focus on HDDs and the spinoff of SanDisk as a separate entity meant that gamers can no longer buy WD storage expansion cards.
These specialized storage expansion cards are only needed if you want to increase the capacity of your console to install more games directly on it. You can still keep your games offloaded on an external hard drive and just plug it into the console when you want to play it again. Crucially, you’ll have to move the games from your hard drive back to your Xbox’s SSD to ensure the games run properly, which is why these expansion cards are a popular alternative.
This is a different take from Sony’s PS5, which comes with an NVMe slot right on the console. This means that you don’t have to buy proprietary PlayStation SSDs to upgrade the capacity of the console — any PCIe 4.0 NVMe SSD would work, making capacity upgrades cheaper. The Nintendo Switch 2 took a similar approach, where it allowed users to upgrade the capacity of their handhelds with a microSD Express slot. It must be noted that microSD Express cards are quite niche, though, and more expensive than ordinary microSD cards, but they could potentially be used on other devices that have a similar slot, making them far more useful compared to the Xbox Series X|S expansion cards, which only work with the particular consoles.
