Abstract: A heat dissipation unit used in a memory device includes two heat dissipation sheets, two sides at the top edge of each heat dissipation sheet are bent for respectively forming two lugs having a height difference, and two buckle pieces having a height difference between the two lugs, wherein each lug and each buckle piece of a heat dissipating sheet is mutually stacked onto a corresponding lug and buckle piece of the other heat dissipating sheet, respectively.

Abstract: A housing structure for enclosing a solid-state drive (SSD) is disclosed. The housing structure includes a housing and a height adjustment plate. The housing is used for receiving the SSD and has a plurality of engagement recesses on a surface thereof. The height adjustment plate includes a plate body having a predetermined height and a plurality of hooks formed on the plate body. The hooks correspond to the engagement recesses in position and the height adjustment plate is fastened to the housing by engaging the hooks with the engagement recesses for adjusting an overall height of the SSD.

Abstract: A solid state disk includes a circuit board and a casing. The casing comprises a first cover and a second cover. The circuit board is provided in the first cover. Each side of the first cover is provided with a plurality of first combining portions. Each side of the second cover is provided with a plurality of second combining portions at positions corresponding to those of the first combining portions respectively. The second combining portions are buckled to the first combining portions respectively. Each first combining portion has an extension section extending from the first cover. The extension section of the first combining portion extends to be buckled to the second combining portion. Thus, the first cover and the second cover cannot be detached easily. When the casing is detached, the extension section will get broken, thereby preventing undesired detachment.
