You'll need to know what physical size the disk is and what kind of connector is on it (laptop drives are pretty standard, though). The advantage of that style of cable is that it has both sizes of connector on it, rather than just one of the two, so the cable that can transfer from a laptop drive can also do the same for the larger-sized traditional desktop drives.
