The built-in NVMe SSD enclosure in the M4 Mac Mini Stand & Hub with NVMe 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
