    摘要: Apparatuses having variable communication speeds are disclose. In one example, an apparatus may comprise a controller configured to: receive a signal from a host, the signal being compatible with a data communication protocol at a first data communication speed; selectively implement a first data communication protocol from a plurality of data communication protocols to communicate with a first memory or implement a second data communication protocol from the plurality of data communication protocols to communicate with a second memory based on the data communication speed; store data in the first memory via the first data communication protocol when the data communication speed is a first speed; and store data in the second memory via the second data communication protocol when the data communication speed is a second speed that is different than the first speed.

The stud includes a first screw coupling hole formed in an upper portion and a second screw coupling hole formed in a lower portion, and is inserted into the stud insertion hole to be fixed to the base plate. The first screw insert hole is formed at a position of the cover plate disposed over the base plate corresponding to the stud. The first screw is inserted into the first screw insert hole to be coupled to the first screw coupling hole so that the cover plate is coupled to the base plate. The second screw insert hole is formed at a position of the PCB disposed under the base plate corresponding to the stud. The second screw is inserted into the second screw hole to be coupled to the second screw coupling hole so that the PCB is coupled to the base plate. A protective cover is disposed under the base plate to cover and protect the PCB. The protective cover is also coupled to the base plate by the second screw coupled to the second screw coupling hole of the stud.
