- Operating Systems: Windows, Mac OS, Linux.
- Devices: Laptops, MacBook Air, MacBook Pro, Personal Computers, iMac, iPad, Xbox, Nintendo Switch, PS5, Phones.

7. Heat Dissipation
The YM28P is engineered for optimal thermal performance to ensure stable operation during heavy use:
- Material: Made of aluminum alloy and ABS material, known for efficient heat conduction.
- Design: Features an M.2 aluminum heatsink, nano silicone thermal pad, and air convection design to dissipate heat effectively.

8. Troubleshooting
- Insufficient Power for Peripherals: If connecting multiple power-hungry peripherals (hard drives, monitors) or using on a desktop computer, it is recommended to use a power supply of 60W or more to power the docking station through the PD input port.
- SSD Ejection Issues (Mac Users): Some users have reported internal SSD ejection when inserting other drives. Ensure adequate power supply is connected to the hub. If issues persist, consult Yottamaster support.
- Bus Power Instability: If devices disconnect when unplugging other peripherals, the bus power may be finicky. Ensure a stable power supply is connected to the PD port.
- SSD with Heatsink Not Fitting: The enclosure depth may be shallow. If your SSD has a heatsink, it might protrude, preventing the cover from closing. This may require leaving the cover off or using an SSD without a heatsink.
