No. The USB2-2PORT shares up to 500mA of available power between both USB ports, which is generally not enough to reliably power two bus-powered external hard drives. One or both drives may disconnect or fail to operate correctly.
Why Can't the USB2-2PORT Reliably Power Two External Hard Drives?
The USB2-2PORT does not have its own external power adapter. It receives power from the computer's USB port and shares that available power between both downstream USB ports.
Bus-powered external hard drives can require significant USB power, particularly when starting up or during disk activity. If the connected devices require more power than the hub can provide, one or both drives may disconnect from the USB bus.
The USB2-2PORT is best suited for low-power devices such as keyboards and mice, or self-powered devices that use their own external power supply.
What Should I Use Instead?
If you need to connect external hard drives, use drives with their own power adapters or connect them through a powered USB hub that can provide sufficient power to each device.
