Some people say that the SSD has been used several times, right?

Any storage device has its own service life, or the number of times of use, so does the solid-state hard disk. At present, MLC or SLC particles are widely used in mainstream SSD. The number of times that SLC wafer can be written repeatedly is about 6,543.8+10,000, which is used for high-end solid-state hard disks, while MLC wafer can be written repeatedly for 6,543.8+10,000 times. At present, the vast majority of solid-state hard disks use MLC chips.

Everything has a service life, and SSD is no exception. As long as you don't download things frequently and format your hard disk frequently, you don't like questions. Mechanical hard disks are actually more prone to failure than solid-state hard disks.

Solid-state hard disk (SSD) is a hard disk composed of an array of solid-state electronic storage chips, which is composed of a control unit and a storage unit (FLASH chip and DRAM chip).

Solid-state hard disk is exactly the same as traditional hard disk in interface specification and definition, function and usage, as well as product appearance and size, but I/O performance is greatly improved compared with traditional hard disk.

The working temperature range of the chip is very wide, including commercial products (0~70℃) and industrial products (-40~85℃). Although the cost is high, it is gradually spreading to DIY market.

SATA-3 interface, M.2 interface, MSATA interface, PCI-E interface, SAS interface, CFast interface and SFF-8639 interface are widely used in the new generation of solid state drives.
