Description

Technical Field

[0001] The utility model belongs to the technical field of electrical appliance assembly, in particular to a data storage unit assembly structure. Background Art

[0002] Flash-based SSDs are the main category of SSDs, and their core components include the main control chip, cache particles, and flash memory chips. The main control chip is the core of the SSD. Its functions are to reasonably allocate the data load on each flash memory chip and to undertake the entire data transfer, connecting the flash memory chip and the external SATA interface. The capabilities of different main controls vary greatly, and there will be very large differences in data processing capabilities, algorithms, and read and write control of flash memory chips, which will directly lead to a performance gap of several times between SSD products. Cache particles are generally located next to the main control chip. SSDs, like traditional hard drives, require high-speed cache to assist the main control chip for data processing. Cache particles are relatively fragile components and are easily damaged by vibration. In addition to the main control chip and cache chip, most of the remaining positions on the PCB board are NAND Flash chips. NAND Flash chips are divided into four specifications: SLC, MLC, TLC, and QLC. The more unit layers there are, the higher the performance is, but the corresponding vibration resistance is worse. At present, the packaging structure of solid-state drives is already sufficiently reliable in terms of dust resistance, but its vibration resistance has yet to be improved, especially when used as a mobile storage device. Data storage units including cache particles and flash memory chips are easily damaged by external mechanical vibrations. Once data is damaged, the loss is difficult to estimate. Summary of the invention

[0003] The technical problem to be solved by the utility model is: how to improve the vibration resistance of the data storage unit.
