However, you’re able to also still use a regular USB-connectedXbox external hard drive or SSD.

But which is best, and which should you buy?

In terms of portability, both are superb options to take on the go or between devices.

Seagate Expansion Card

Naturally, you could only take the official expansion card to another Xbox Series console given its bespoke design.

An external hard drive, by comparison, will offer slower speeds.

Sometimes its the non-gaming-focused external SSDs that offer terrific value here.

If youre a Game Pass stalwart, then the capacities offered here might be the better bet.

As a result, the difference in price is stark, but so is the value proposition.

However, these often have an imposing price tag so it might be beyond some budgets.

The extra performance you get for your investment means that the smaller sizes are a fair trade-off.
