Solid state disk

1. A solid state disk, including:

a main body, including a shell portion, a substrate which is disposed on the shell portion and a memory module which is disposed on the substrate, the shell portion having a light-penetrable shell portion, the substrate having a light-penetrable portion and a first face, the substrate integrally formed with the light-penetrable portion, the first face having a first coating layer, the first coating layer having an emergent light-penetrable portion corresponding to the light-penetrable portion, the light-penetrable shell portion corresponding to the emergent light-penetrable portion, the substrate including a transmission port, the memory module electrically connected to the transmission port;

a light-emitting portion, buried in the substrate and electrically connected to the transmission port, a light emitted from the light-emitting portion being capable of being projected toward an interior of the substrate to the light-penetrable portion and the emergent light-penetrable portion and via the light-penetrable shell portion to an exterior of the solid state disk.

2. The solid state disk of claim 1 , wherein the light-penetrable shell portion includes a decoration plate on the shell portion and a light-penetrable pattern portion disposed on the decoration plate.

3. The solid state disk of claim 2 , wherein the emergent light-penetrable portion and the light-penetrable pattern portion correspond to each other in position and shape.

4. The solid state disk of claim 1 , wherein the first coating layer at least covers a part of the light-emitting portion.

5. The solid state disk of claim 1 , wherein the substrate further has a second face opposite to the first face, the substrate further includes a second coating layer on the second face, and the second coating layer at least covers a part of the light-emitting portion.

6. The solid state disk of claim 1 , wherein the light-emitting portion includes a plurality of light-emitting diodes which are disposed on the substrate and substantially along a contour of the emergent light-penetrable portion.

7. The solid state disk of claim 1 , wherein the light-emitting portion is emittable in any of at least two kinds of light in different colors.

8. The solid state disk of claim 1 , wherein the substrate is further provided with a processing unit, the processing unit is electrically connected to the light-emitting portion, and the light-emitting portion is controllable by the processing unit.

9. The solid state disk of claim 1 , wherein the light-penetrable shell portion includes a decoration plate on the shell portion and a light-penetrable pattern portion disposed on the decoration plate; the emergent light-penetrable portion and the light-penetrable pattern portion correspond to each other in position and shape; the substrate further has a second face opposite to the first face, the substrate further includes a second coating layer on the second face, the second coating layer completely covers a part of the second face corresponding to the light-penetrable portion, and the first coating layer and the second coating layer completely cover the light-emitting portion; the light-emitting portion includes a plurality of light-emitting diodes which are disposed on the substrate and substantially along a contour of the emergent light-penetrable portion; the light-emitting portion is emittable in any of at least two kinds of light in different colors; the substrate is further provided with a processing unit, the processing unit is electrically connected to the light-emitting portion, and the light-emitting portion is controllable by the processing unit.
