Its disadvantage is that when the number of hard disks in the front-end hard disk module is large, the number of cables plugged in the rear end will also increase accordingly. The problem. The characteristics of the cable being soft and easy to bend make the middle part of the cable inconvenient to organize after the cable is inserted, resulting in disordered, unsightly, untidy cables, and even wrongly inserted and connected by cables. Hot-plug maintenance is not possible.
