Why buy the WD_Black C50 Storage Expansion Cards for Xbox?

Aside from having plentiful install space, Western Digital's WD_Black C50 Storage Expansion Cards for Xbox's major selling points include an eye-pleasing, compact design that makes it easy to store while traveling, a nice and simple installation method, and a durable build.

Performance-wise, these SSD cards can match the Xbox Series X|S's internal SSD Read Speeds of 2.4GHz and Write Speeds of 4.8GHz by using Xbox Velocity Architecture. This means that when you're playing games directly from the cards, their performance will not suffer for it and run as well as if they were installed in the internal SSD.

That's another cool thing about the WD_Black C50 Storage Expansion Cards: you can directly launch and play games installed in them, instead of having to constantly be shuffled to fit into the console's internal SSD like you would external SSD drives.

Combine this with Quick Resume compatibility to prevent you from losing progress while you turn the console off, and more affordable price tags compared to Seagate's Xbox Storage Expansion Cards (e.g., $212.49 for WD_Black's 2TB expansion card vs $274.99 for Seagate's 2TB expansion card), and you've got one of the best, bang-for-your-buck SSDs you can buy for your Xbox's storage unit.
