What is the difference between SLC, MLC, and TLC flash chip particles?

In the U disk, SSD and other solid-state storage products, flash chip particles is the core, which relates to product costs, life and speed. Flash chip particles are mainly three types, respectively, SLC, MLC, TLC, the difference between the three, as follows.

What is the difference between SLC, MLC, and TLC flash chip particles?

SLC = Single-level Cell, that is, 1bit/cell, long life, the price is expensive (about MLC 3 times times more than the price), about 100,000 times to erase life;

MLC = Multi-level Cell, that is, 2bit/cell, speed general life general, the price is general, about 3000---10,000 times to erase life

TLC = Trinary-level Cell, that is, 3bit/cell, also has flash factory called 8LC, Low speed, short life, cheap, about 500-1000 times to erase life.

Comparison of characteristics of MLC and TLC

Conclusion: SLC > MLC > TLC

At present, most u disk are using TCL chip particles, the advantage is that the price is cheap, but the general speed, life is relatively short.

SSD solid-state Drive, the current MLC granular solid-state drive is the mainstream, its price is moderate, the speed and life is relatively good, and Low-cost SSD solid-state hard drive is commonly used in TCL chip particles, we buy solid-state hard disk, you can in the product parameters to understand, as shown in the following figure.

SLC particle solids are now mainly found in some high-end solid-state drives, selling at most thousands of dollars or more.
