How Much Storage Does the Xbox 360 Arcade Have?

The Xbox 360 Arcade model does not include an internal hard drive. It shipped with 0 GB of built-in storage.

Storage Options for Arcade Owners

• USB Flash Drives: You can connect a USB drive (up to 32 GB formatted by the console, or larger with specific formatting) to store game saves, profiles, and downloadable content.
• Memory Units: The console supports the older Xbox 360 Memory Units (256 MB or 512 MB) that plug into the memory card slots.
• External Hard Drive (Later Models): Some later Arcade bundles included a 256 MB or 512 MB internal memory unit, but never a full hard drive. You cannot install a standard 2.5" SATA drive without the proprietary hard drive enclosure/caddy used by Pro/Elite models.
• Xbox Live Marketplace: Games and content can be purchased and streamed/downloaded directly, but limited local storage restricts how much you can keep installed.

If you plan to play disc-based games that require mandatory installs or download large titles, upgrading to a model with a hard drive (or purchasing an official Microsoft hard drive enclosure separately) is highly recommended.
