Well worth it. – Got this for my son to expand his Xbox capacity. His Xbox has a 1 TB memory, but he quickly filled that up with some of the larger games he’s been downloading. I had been looking for a reasonable expansion card, and found this one at Best Buy. The cost was reasonable, it was Plug and Play, and it more than met the need.
Kyle (verified owner) –
Works well – The product works well, wish the console came with more space naturally though.
JamesT (verified owner) –
Completed the experience – Simple and easy, plug and play literally. Completely expanded the horizons for what I could have downloaded on my series s and allowed for almost 2x the amount of games compared to the base series s

Needed expansion – I bought one for myself when Xbox first launched and had to get one my son too! Easy to use, never lost a single file, loads games from the expansion quickly!
