The built-in NVMe SSD enclosure in the Mac Mini M6/M5 Pro/M4 Stand & Hub with SSD Enclosure supports transfer speeds of up to 10Gbps.

The Mac mini port itself is faster, but the enclosure inside the hub uses USB 3.2 (10Gbps), so 10Gbps is the maximum speed for a drive installed in the enclosure.

• Host cable: USB-C 3.2 Gen 2
• M.2 NVMe SSD enclosure: up to 10Gbps
