Yes, all ports on the Mac Mini M4 Stand & Hub with SSD Enclosure can work at the same time, including the SD card slot. The hub is bus powered, which means it draws power from your Mac mini and shares that power and data bandwidth across the ports.

For the best performance, use one storage drive at a time.

Supported peripherals include:

• External hard drives (one at a time)
• Flash drives
• USB mice and keyboards
• Headphones and microphones
• Webcams

Please note: the USB-A ports do not charge iPads and do not support CD or DVD readers, including the Apple SuperDrive.
