I am once again telling Xbox gamers not to buy the Seagate Expansion card

Not all Cyber Monday deals are built equally - and we often get a hint that some might be worse than others months in advance. Back in October Amazon held its Big Deal Days event, marking the second Prime-exclusive sale of the year. As always, it sparked loads of other retailers to join in the fun and do a dress rehearsal for Cyber Monday, and while scouring the shelves, I noticed that Xbox gamers weren't getting the best value for money they could.

If you play on Xbox Series X or S, you have two options if you want to expand your internal storage. On one side, you have the popular, and well-known Official Seagate Expansion Card, and then you have the WD Black C50 - which only launched earlier in 2023. 

While the Seagate option is usually the one most people flock to when it comes to these big deal events, the WD Black C50 is often the cheaper of the two. Right now, in a Cyber Monday Xbox deal for example, you can get the 1TB WD Black C50 for only $124.98, whereas a 1TB Seagate Expansion Card will set you back $129.99 - and that's if you can find stock of it. 

The differences in price here aren't exactly massive, but it's worth knowing that these two storage devices are functionally the exact same. They're both an extension of the console's internal storage, meaning they slot in the back of your Series S or X, and can both launch your games in a heartbeat. Out of all the best Xbox Series X hard drive options out there, these are the only two that Quick Resume will work with. In other words, these are as close as you'll get to an internal NVMe SSD for the PS5.

Save $25 - Back down to its lowest-ever price that we first found during October's Prime Day, the WD Black C50 in a 1TB capacity is well worth considering for your Xbox Series X or S.

Buy it if:
✅ You want to Quick Resume games from an expanded drive
✅ You want the best value for money in a 1TB deal

Don't buy it if: 
❌ You want 2TB
❌ You don't mind a cheaper external drive

Save £20 - Also on sale in the UK, the WD Black C50 is the best way to upgrade your Xbox storage this Cyber Monday. We haven't seen this price since the summer in the UK, so this is an even better time to pull the trigger. Lucky for UK shoppers, you even get a month of Game Pass membership for free with this accessory because it's officially licensed.

Buy it if:
✅ You want to Quick Resume games from an expanded drive
✅ You want the best value for money in a 1TB deal

Don't buy it if: 
❌ You want 2TB
❌ You don't mind a cheaper external drive

Cyber Monday is all about making your money go further, so I wouldn't be doing my job right if I didn't tell you that there's absolutely no need to fork out more money on the Seagate Expansion Card when WD Black's option is far easier to get stock of and is a bit more affordable.

The only caveat has to be that if you need more than 1TB, Seagate is your only option. For some reason, the C50 doesn't come in a 2TB form. The bad news is that Seagate's 2TB expansion almost knows that it has a monopoly in that department, and it doesn't come cheap. 

As someone who reviews the best SSDs for gaming and the best external hard drives for gaming, charging $229.99 for 2TB of this Xbox-specific storage seems absolutely sinful to me. That's literally $100 more for 1 extra terabyte, which, let's be completely honest, no one really needs. It's amazing how 1TB extra can turn you into a game-hoarding dragon that never deletes anything, but filling up just one extra terabyte can actually be a struggle. 

To me, there's no real reason to buy the 2TB version of the Seagate Expansion Card, especially when, if you actually need that space, you can always grab a Cyber Monday external hard drive deal instead.

Ever since playing Journey at the age of 15, I’ve been desperate to cover video games for a living. After graduating from Edinburgh Napier University with a degree in Journalism, I contributed to the Scottish Games Network and completed an Editorial Internship over at Expert Reviews. Besides that, I’ve been managing my own YouTube channel and Podcast for the last 7 years. It’s been a long road, but all that experience somehow landed me a dream job covering gaming hardware. I’m a self-confessing PlayStation fanboy, but my experience covering the larger business and developer side of the whole industry has given me a strong knowledge of all platforms. When I’m not testing out every peripheral I can get my hands on, I’m probably either playing tennis or dissecting game design for an upcoming video essay. Now, I better stop myself here before I get talking about my favourite games like HUNT: Showdown, Dishonored, and Towerfall Ascension. Location: UK Remote
