In recent years, with the continuous development of mobile phone images, photos and videos occupy a lot of storage space. In the increasingly inflated Wechat, mobile games and all kinds of APP, 128GB storage is really not enough. If you put it in 2023 and ask me to recommend a cell phone,My first choice is 256GB, followed by 512GB and 1TB.

If there is not enough space, causing the phone to stutter, the phone keeps reminding you that there is not enough space left, and you need to delete software and photo albums, which is really bad, so it is really important to set aside part of the budget to buy large storage when you buy a mobile phone. & nbsp

Today we talk about the flash memory standard adopted by the mobile phone storage capacity (ROM). The reading and writing speed of the flash memory of a mobile phone will directly affect the installation speed of the software, the loading speed of the APP, the opening speed of photos and other files. & nbsp; the common mobile flash memory standards on the market are eMMC, UFS and NVMe.

Android phones mainly use eMMC and UFS standards, while NVMe is the flash memory standard used by Apple iPhone. 1 understand the specification of mobile phone flash memory

At present, the latest eMMC5.1 standard, the continuous reading speed is about 250MB/s, which is not enough under the current software. at present, there are only 100 yuan low-end computers in use.

UFS

The first generation of UFS was not successfully popularized because of its small difference in speed and high cost with the eMMC standard at that time. Until the advent of the UFS2.0 standard in 2014, the continuous reading speed of about 800MB hand has gradually become the standard configuration adopted by the flagship of Android. & nbsp

When UFS3.0 came out in 2018, the continuous reading speed was about 1700MB/s, gradually catching up with Apple NVMe. At present, UFS4.0 is released in 2022, and the continuous reading and writing speed has been able to achieve 3400MB/s.

The flagship Android released in 2023 basically uses the flash memory of UFS4.0. The difference between eMMC and UFS on Android phones can basically be understood as the difference between HDD mechanical hard drives and SSD solid-state drives on PC.

NVMe

NVMe (NVMExpress) is originally the flash memory standard of SSD solid-state disk used on MacBook, which has the characteristics of high efficiency, low load and low latency. & nbsp; in 2015, Apple first used NVMe flash memory on the iPhone6S, when the continuous read speed was about 500MB/s.

In addition, the ability to use NVMe flash memory is related to the fact that Apple's A9 chip began to use PCIE interface. Later, Apple's WiFi and baseband all use PCIE interface, and their own chip interface is defined by themselves, which other manufacturers really can't learn.

It was not until the advent of the UFS3.0 that the gap between the two gradually narrowed. Apple's NVMe has also been upgraded in recent years, nearly quadrupling since the iPhone6S. At present, the latest iPhone14ProMax continuous read and write performance is about 1500MB/s. & nbsp;, so in the section of continuous read and write performance: UFS4.0 > NVMe=UFS3.1 > UFS2.1 > eMMC5.1

For different mobile phone flash memory specifications, except for the difference in file reading and writing speed, the serial transmission technology adopted by UFS and NVMe can read and write mobile phone data at the same time; & nbsp; while the parallel transmission technology adopted by eMMC must perform read and write operations separately.

Therefore, when mobile phones perform multitasking, the response speed of eMMC is much slower than that of UFS and NVMe standards, which is why eMMC has been eliminated with the development of science and technology. & nbsp; in addition, the average daily power consumption of UFS and NVMe is also lower than that of eMMC. & nbsp
