Replacing a solid state drive in a laptop is recommended to be done by a professional. Replacing it yourself is likely to damage your computer.
Named because solid capacitors are called Solid in Taiwanese English, SSDs consist of a control unit and a storage unit (FLASH chip, DRAM chip).
SSDs are identical to ordinary hard drives in terms of specification and definition of interfaces, functionality and usage, and are basically identical to ordinary hard drives in terms of product form factor and dimensions (the emerging U.2, M.2 and other forms of SSDs are completely different in size and form factor from SATA mechanical hard drives).
Widely used in military, automotive, industrial control, video surveillance, network monitoring, network terminals, power, medical, aviation, navigation equipment and many other fields.
Flash-based Solid State Disk (IDEFLASH DISK, Serial ATA Flash Disk): Using a FLASH chip as the storage medium, this is also commonly referred to as an SSD, which can be made in a variety of ways, such as laptop hard drives, microdisks, memory cards, flash drives, and other styles.
The biggest advantage of this SSD solid state drive is that it is mobile and the data protection is not controlled by the power supply, it can be adapted to a variety of environments and is suitable for individual users. The lifespan is long and varies depending on the flash media. SLC flash generally reaches PEs of tens of thousands of cycles, MLC can reach more than 3,000 cycles, and TLC reaches about 1,000 cycles.
The latest QLC also ensures a lifespan of 300 times. The average user writes no more than 50 times the total size of the drive in a year, and even the cheapest QLC flash can provide a 6-year write life.
