I have sought a solution to transfer easily the old data when hard disk replacement can, this cable is just the thing for that. Thanks to USB 3.0, the transfer is fixed and it is much simpler than with SATA connectors rumzufummeln am Main board, which then after copying must be abgefummel again. It's all plug and play, only the cables can be longer NEN touch. Especially on laptops there except an external HDD enclosure few alternatives to a "naked" hard drive to connect.
