You don't need me to tell you that video games are taking up more storage space than ever before. So when Cyber Monday rolls around, it's a good time to upgrade.
In the case of the Steam Deck, it's the number one upgrade I recommend. I bought a 256GB Steam Deck and received it in the earliest batches, and it didn't take long to need more. My SSD of choice — the Crucial P310 — is reduced right now, with 1TB down to $84.99 $97.77 at Amazon.
Don't think this deal is just for the Steam Deck, either — all mainstream PC handhelds, from the Xbox Ally to the Legion Go, can benefit.

Alternative deals
There's not much that needs saying. If you don't have 1TB or more already in your handheld gaming PC, then this is the upgrade to make. It's good for the Steam Deck, it's good for the Lenovo Legion Go, it's good for the Xbox Ally, and any other handheld that uses the m.2 2230 form factor SSD.
The Crucial P310 is a strong performer, with read speeds up to 7,100 MB/s. Chances are it could even be a little faster than the stock SSD in your handheld, even if not by much.
There's also the fact that at this Cyber Monday price, this is also about the cheapest upgraded SSD you could put in a Steam Deck, so it gets extra points for that.
We have guides on upgrading the SSD in the Steam Deck, the ROG Ally, and the Legion Go to help you on your way. But all you need is a little patience, and a screwdriver. The Steam Deck is probably the most involved process from the software side, but the results are well worth it.
The alternative is to use a microSD card. Sure, these are cheap, but they're also slow. For lighter games, this option isn't so bad, so I'll include a couple deals below. But you don't want to be loading Cyberpunk 2077 from a microSD card!
We've also been covering other deals on the Steam Deck, Lenovo Legion Go S (SteamOS), and related handheld accessories for Cyber Monday.

FAQ
How do I upgrade my Steam Deck SSD?
Opening your Steam Deck (or any gaming handheld) to upgrade the internal storage may seem like a daunting task, but we have step-by-step guides for Steam Deck, ASUS ROG Ally, and Lenovo Legion Go.
Why should I upgrade my Steam Deck SSD?
The obvious answer for why it's worth upgrading your handheld's SSD is so you have much more space for installing all your games. Only the highest-end Steam Deck comes with 1TB of SSD storage, and most handhelds don't have any option for more than that out of the box. However, upgrading your SSD can also noticeably improve your handheld's performance, as the best SSDs you can buy and install yourself are usually faster than the SSDs handheld manufacturers use.
What day is Cyber Monday 2025?
Cyber Monday started on Monday, Dec. 1, 2025, but, as with Black Friday, it already began appearing as the theme for deals at certain retailers in the days before. While its discounts are generally restricted to the day itself, some deals may extend into Tuesday and beyond.
When does Cyber Monday end?
Cyber Monday technically ends at 11:59 p.m. local time on Monday, Dec. 1, 2025, and most promotions will cease at the same time. Retailers often run deals in the days following Cyber Monday, in case you miss a deal the day of, but that's never a guarantee.
