Description

Portable Solid State Drive with silicone cover The present invention relates to a portable data storage device, wherein a silicone cover is fixed and coupled to the outside of a case to block heat dissipation, protect internal structures from external impacts, and provide a dustproof and waterproof structure. A portable solid-state drive (PSSD) is portable and provides a reliable storage solution with fast data access speeds. Examples of prior art include Published Patent No. 10-2015-0040849 (storage system having a heatsink), Published Patent No. 10-2024-0157917 (external data storage device), and Registered Patent No. 10-2653809 (portable storage device having a modular power and housing system). These portable storage devices are composed of a memory module and electronic components including a plurality of non-volatile memory cell arrays for storing data received from an external device, and a rigid case composed of a plurality of planes surrounding the memory module and electronic components, and may additionally have a heat sink structure for dissipating heat generated from the memory module and electronic components through an aluminum case. However, portable storage devices according to the prior art have a rigid case structure, which can easily damage not only the case but also the internal memory modules and electronic components due to external impacts such as drops, potentially leading to damage to important data. Additionally, because the case is exposed to the outside, users may experience discomfort from heat dissipation or face a risk of low-temperature burns. In addition, since it lacks a dustproof and waterproof structure, it has the problem that data damage may occur if it is exposed to dust or water. <Prior Art Literature> 1.
