TLDR at the very bottom I was skeptical about buying one, all that money for storage, really? No thank you. Well... that worked for me for a while lol but eventually I hit that point where it was unavoidable, I had to get something. I deal with tech all the time, I'm no expert, but I'd like to think my judgement is solid, fair, and reasonable. Anyway I'll get on to it. Pros: I know being pricey isn't exactly a pro because it is no doubt expensive but in my honest opinion it's well worth it for both but especially the 1TB. I would recommend waiting for a sale or something if you're strapped. Don't fall for FOMO. They're extremely reliable, function is genuinely impressive(no exaggeration, it is just as advertised and is just as fast as the internal drive), it is compatible with both the Xbox Series X & Xbox Series S ONLY, should be obvious but just in case. I do like the design it is very sleek, sexy, and thin but still built solid. It reminds me of the memory cards for all the old consoles we had to buy back in the day. The quality impressed me as well, no it's nothing revolutionary, but they are bult very well and they have a clear protection cap to put on the end of the card for when/if you take it out of the console so it doesn't get scratched. Small thing but I like the size, I was expecting it to be massive-ish but it's kinda tiny Cons: I do wish it wasn't as much as it is, it is a lot of money but you CAN find deals, also look at the New & Used section as well. I still feel like it's worth it for the 1TB but the 2TB price is ridiculous. $250+ - $350+ cannot be justified. It's worth MAYBE $220 at most. I wish there was a hub for the Series X and S so you could have 2 Storage Expansion Cards plugged into the console all at once because I have three of the 1TB Cards. Be VERY careful pulling it OUT of the console, it can scratch the plug in part of the Card easily so take it out as straight as possible if you have to take it out. Don't be wiggling it. The scratches won't ruin it but still... be careful. Anyway TLDR; I do recommend it, very solid product and I think the 1 TB is the perfect option but if you do have the money I'd get the 2 TB but ONLY if the 2TB is on sale. Don't forget sometimes they have the payment plans and also look for some that are in the New & Used section, you can genuinely get better prices occasionally and yes they are worth it even if it is Used. Might get one with a slight scratch or tiny cosmetic damage. They always test the product before sending it to you.

For years, I used an external SSD with my Xbox, and while it did the job, it had its limitations — especially when it came to playing Series X/S games. When I saw this 2TB expansion card on sale during Prime Day, it was an instant buy. Funny enough, I paid about the same price years ago for an SSD with 1TB less storage and none of the X/S perks. This card is made for Xbox. It slides right into the dedicated slot, supports full Series X/S performance, and works flawlessly with Quick Resume. No setup headaches, no transferring files around — just plug in and play. With the size of modern games constantly climbing, this is practically a must-have. If you’re like me and enjoy rotating through a bunch of titles (not just GTA V and Call of Duty), having 3TB of total storage means no more uninstalling one game just to play another. Finally. If you're still managing space manually or stuck on external drives that can't run next-gen games natively — do yourself a favor and upgrade. This was worth every penny.

Wow makes all the difference !! Content seamlessly loads and plays from card without any issues . I have my series x console storage empty and just keep everything on the card - i love it . A teeny tiny bit pricey but worth it . It is very very reliable. I waited months to write review to make sure there were NO issues and still to date , NONE. An Xbox gamer must have.Large capacity and i have seen no power drain or glitch while i am gaming because i am using the card . Great for games like Halo and COD that can get up there in GB !

Seagate has always been a top product for me when it comes to buying accessories for my XBOX consoles. Even though the initial price is steep, totally worth it since now I can play all my high storage games no problem! Small and compact is great since now I do not have to worry about cleaning it off all the time. Connects to my XBOX no problem and is great quality like always. Super easy to use as you just plug it in and transfer games to the storage. Great product!

Amazing product. Works as described and the quality is on point. Compatible with an xbox series x. No need to format upon opening up. Just put into xbox series x console and you're good to go. Weighs barely nothing and there is no noise made. 5*

Handy dandy just plug it into your Xbox and bam. My main issue is that the price for these proprietary cards is pretty darn expensive for the storage capacity but the convenience and ease of use kind of counters that factor.
