The M1 Mac Mini has two Thunderbolt 4 ports These ports also support USB 4, giving you flexibility for high-speed external storage without sacrificing connectivity.

Two USB-A ports are included for slower drives Use these for backup drives or older peripherals, but avoid them for primary storage if you need speed.

Thunderbolt 4 is backward compatible with USB-C You can plug in USB-C drives, but they will run at USB speeds, not Thunderbolt speeds.

External Thunderbolt storage is the only upgrade path Since the M1 Mac Mini has no internal expansion, a Thunderbolt SSD is the best way to add fast, reliable storage.
