In addition to Apple's NVMe standard on iPhone PCs, Android's flash memory is mainly eMMC 4.5/5.0/5.1 and UFS 2.0/2.1. The current maximum speeds of eMMC and UFS are 400MB/s and 1166MB/s respectively. On September 12, it was reported that Quanlian Electronics, which produces flash memory controllers, had disclosed some UFS 3.0 information at the storage industry exchange meeting held with Shenzhen earlier.

UFS Roadmap

The theory of UFS 3.0 standard has doubled dramatically compared with the previous generation, reaching 2400MB/s, which is 6 times of eMMC. However, UFS 3.0 is still in the development stage, and even Snapdragon 835 only supports UFS 2.1. It will be 2019 before it is really widely used by flagship mobile phones. However, there are few news about eMMC 5.2, only mentioning that it will be released at the end of this year.

A few days ago, Huawei's flash memory mixing event forced the public to popularize a large wave of eMMC and UFS knowledge, and many evaluation institutions finally added flash memory read and write tests. The double speed sounds good, but UFS 3.0 will not be available until two years later, and the increase is far from the expected medium high.
