Solid-state hard disk download more things easily bad?

Is the solid state hard drive downloading something bad ?

In fact, whether it is a solid-state hard disk or traditional mechanical hard drive, in fact, there is the concept of life, the white is any hardware products have this concept of life. The user is worried that the solid-state hard disk downloads things easily bad, is actually worried about the SSD life problem.

Solid State hard drive internal flash memory is called 1 times P/E, so the life of the flash memory is P/E as a unit. 34NM of flash memory chip life is about 5,000 times p/e, and 25nm life is about 3,000 times p/e, from the surface, solid-state hard disk life seems very short. But by studying the information, we will find that this worry is completely superfluous.

For example, we have a 120G solid-state hard drive, to write 120G files to be counted as a P/E. Ordinary users boast normal use, even if exaggerated, write 50GB a day, the average 2 days to complete a P/E, then 180 times a year P/E, such a calculation, the theory of solid-state hard disk life also up to more than 10 years, and in fact the general mechanical hard disk life is not ten years.

The decision of SSD solid-state hard disk life is mainly determined by flash particle and solid-state hard disk capacity, SSD Flash granules are usually two kinds of MLC, SLC can read and write 100,000 times, and the MLC is only 10,000 times, so solid-state drives with SLC granules are more expensive, but their life expectancy is also better.

For ordinary users, the general BT download and daily use, MLC granular flash chip solid-state drive to meet the demand, users need not worry about downloading life-affecting problems. If the real life of the special requirements, as far as possible selective SLC particles of solid-state drives. In addition, most of the current brand solid-state hard disk will provide three years of free warranty service to ensure quality, we have to do as much as possible to buy some well-known brand reliable SSD, to avoid second-hand or cottage products, is the most important.
