Don t worry about whether it s MSATA or EMMC

SSD has become a catalyst for the performance of PCs, and eMMC has a huge role for Apple iPads, Android tablets, and mobile phones. Different from our common SSDs or NGFF MSATA SSDs, EMMC actually packages the main control and flash memory wafer die unit in a chip chip, which looks no different from ordinary flash memory chips, and this all-in-one package is called eMMC.

Strictly speaking, eMMCs and SSDs are not exactly the same thing. The English name for eMMC is "Embedded Multi Media Card", and the SSD stands for "Solid State Disk". SSD is an array of storage composed of multiple flash memory chips, main control, and cache, like a large battleship with dozens of guns; The eMMC is a particle chip composed of a single flash memory chip and a single main control, which is equivalent to a small gunboat with only one artillery.

The structure of eMMC is extremely simple, and in a broad sense, TF cards and SD cards also belong to eMMC, from which we can also see the advantages of eMMC: ultra-small size, low complexity, high integration, and low wiring difficulty. And its disadvantages are also quite obvious, SSD is multi-channel read and write, and its master controller quickly distributes data to multiple flash memory chips for transmission, while EMMC can only allocate one flash memory chip.

EMMC made of a single flash memory chip is equivalent to a smaller and streamlined SSD

8 io data lines need to be matched with clk, cmd as much as possible.

They are all memory made of flash particles, different standards and usage methods, and eMMC is used more for mobile phones.

Huawei P10 and PLUS flash memory uses MLC and TLC particles, resulting in the difference in flash memory speed of different mobile phones, and the worst speed can only reach the standard, which is very different from the transmission speed advertised by the official. Because the products of different flash memory chips are completely different in terms of read speed, lifespan, and **. MLC particles are better than TLC's, and the more expensive they are, there is a big price difference.

Profit from it is here, fooling consumers is also here, originally the official said that the mobile phone uses MLC flash memory, and in the hands of users, it is indeed the mobile phone that uses TLC flash memory, and the price spent is indeed MLC flash memory.

I bought it, I bought it, and I knew about the flash memory problem before I bought it, but are you still entangled after buying it now? Don't toss, it's troublesome.

Don't look at it, pretend to be the first prize.

It seems to be in the settings, about the phone.

UFS is a flash memory standard developed by the JEDEC Solid State Technology Association, which is the abbreviation of Universal FlashStorage, and the latest standard is the version of the JESD223C document published in March 2016. Its predecessor was released in 2014.

With the previous generation processor, low-end JDI screen, battery life, EMMC, all kinds of unknown places to cut corners, suddenly feel that OV is still quite cost-effective.

Actually, you don't have to care so much about whether it's EMMC or UFS, let's show you a comparison table:

4. Coordination with memory: Now mobile phones are all 2G memory, and some even reach 6G LPDDR4, which is the embodiment of speed and efficiency. The impact of UFS and eMMC team speed is far less than the speed impact of memory size on mobile phones.

The most intuitive example is that you add a large hard disk to your computer, which is far less fast than adding a memory module.

5. The system itself: Like the storage and memory of Apple mobile phones, they are so small, but it feels faster than Android phones, is the speed determined by hardware? System optimizations have a big impact, such as memory invocation and persistence.

Summary: To sum up, there is no need to worry about EMMC or UFS, paying attention to the GPU, the high appearance of the screen, and the durability of the battery are what mobile phone users should really care about.

It can be used on smartphones, smart wearables, IoT system devices, tablets, or thin and light laptops. BIWIN's eMMC has been doing well, and their self-developed QNAND brand eMMC has always been the darling of the market for smartphones and tablets.

32G refers to the size of the hard disk.

eMMC refers to the interface of a hard disk.

It is a built-in hard disk.

It's about the same as an SSD, but it's slow...
