1. When plugging in the cable, be sure to identify the correct direction. Do not plug it in reversely or misaligned, as this may damage the equipment. When inserting the cable, first hold the device's socket firmly before plugging to avoid breaking the socket pins due to excessive force. Bending or pulling is prohibited within a 2cm range of the soldered joints between both ends of the cable and the circuit board.
2. Various motherboards and devices differ in terms of signal driving capability and other conditions. The test results obtained by our store do not guarantee consistency with your test results. As long as an extension cable is connected, there will be signal loss, which may lead to compatibility issues. If you have high requirements (for signal quality or compatibility), please do not purchase this product.
3. Graphics cards or motherboards are electronic devices that will age and oxidize over time. Connecting an extension cable to them will only make the operation more unstable. This product does not support old devices. If your device is more than three years old, it is not supported. Please do not purchase.
4. This product is restricted to purchase as designated by product engineers and is for product testing purposes only. Please do not purchase it for any other uses.

Summary of technical issues
How should I distinguish between front and reverse side for E1.S and E3.S hard disks?
Please refer to the diagram below and insert the hard disk 
front side up after clarifying the insertion direction.

What are the bracket dimensions for models R27A,R27B,R27C?

How about R27A,R27B,R27C indicator is normal?
R27A and R27B D2 lamp for the power indicator, 
D1 lamp for the read-write lamp, under normal circumstances, 
D1 lamp is always on, D2 lamp read-write state will blink.
R27C under normal circumstances D1 lamp and D2 lamp are always on, 
D1 lamp will be on as long as the device is in the power state,if you need to extinguish the lamp, please turn off the power.

How to fix R27A,R27B,R27C with different types of hard disk?

R27A and R27B are shipped with R27AB screw packs, 
please refer to the installation video for detailed installation procedures;
R27C comes with three types of screw packs, 
please refer to the installation video to use different types of screw packs for different types of hard disk.
Are R27A, R27B and R27C compatible with each other?

R27C is suitable for E1.S hard disk and E3.S hard disk, 
R27A is suitable for U.2 hard disk, R27B is suitable for U.3 hard disk, 
U.2 and U.3 although the interface appearance is the same, 
but the pin definition is different, it can not be mixed, 
please pay attention to identify.
Does model R27C support 5.0?
