Buy SSD SSD Be careful, do you know what is SLC, MLC, TLC flash chip particles?

Solid-State drive with its own advantages such as ultra-fast access rate, by more and more computer enthusiasts favor, and quickly spread to the vast number of users of the computer, because the solid-state drive and traditional mechanical hard disk compared to the efficiency of the operation has been a qualitative improvement, but also is the United States network small to remind everyone is, Buy solid-state drives can not blindly follow the follow-up, to ensure that the solid-state drive to understand some of the basic parameters, information, and then start, buy things to shop around, understand some of the knowledge of solid state hard drive, at least not to let unscrupulous businessmen easily deceive us, take solid-state drive flash chip architecture, what is SLC, MLC, Tlc? Which is good? What is the difference between them? All these need to be understood.

What are SLC, MLC, TLC flash chip particles?

The flash memory chip is divided into SLC, MLC and TLC according to internal architecture, and flash particle is a square body composed of multilayer flash chip.

Flash chip particles directly affect the SSD's access rate, service life, production costs and so on.

SLC, English full name Single-level Cell,1bit/cell, single-layer storage, allows only 1 bits of information to be stored in one memory element.

MLC, English full name multi-level Cell,2bit/cell, multi-layer storage, allows 2 bits of information to be stored in a single memory element.

TLC, full name Trinary-level Cell,3bit/cell, three-tier storage that allows 3 bits of information to be stored in a single memory element.

As a result, the flash particle area is the same, storage volume from small to large: SLC<MLC<TLC.

analysis of advantages and disadvantages of SLC, MLC, TLC flash chip particles

SLC, fast access rate, more erasable (long service life), but production costs are expensive (at least three times times the MLC).

MLC, the access rate is faster, the number of erasable less than SLC (the service life of about One-tenth SLC), the price is general.

TLC, which has a slower access rate and a further reduction in the number of erasable times (One-twentieth of the Life of the SLC), is relatively inexpensive.

buy solid-state drives, choose SLC, MLC, TLC where to go?

Because the MLC structure of the flash chip price is relatively moderate, the service life and the rate is quite good, on the current market structure, most SSDs are using the MLC Flash chip architecture.

Although the SLC, MLC, TLC chip architecture rate is very different, but relative to the traditional mechanical hard disk, are the quality of the soaring, so I recommend different people to use different flash chip architecture of solid-state drives:

For comprehensive performance, data storage, security requirements, economic conditions are abundant, the preferred SLC.

The access rate and other performance requirements, moderate or general economic conditions, the proposed selection of MLC, which is a popular choice.

The same price, no pursuit of performance, only focus on storage capacity, can choose TLC.
