Hello  @zacass ,

Welcome to our community.

Please note that TP-Link routers typically do not support advanced USB HDD features such as dedicated sleep mode or HDD spindown. While this does not directly address slow transfer speeds, it's important to know that the USB port on many consumer Wi-Fi Routers is primarily designed for basic file sharing and may not deliver the same performance as connecting the drive directly to a PC. Actual transfer speeds can be limited by the router's hardware, firmware, and network conditions.

If you are seeing much lower speeds than expected, this is not necessarily a defect, but rather a limitation of the router's USB file sharing capability. For high-speed file transfers or HD media streaming, we recommend using a dedicated NAS (Network Attached Storage) device or connecting the HDD directly to your computer for best performance.

Best Regards.
