Not afraid of flash door! 3 ways to teach you seconds to identify the phone storage type

Whether the storage of Huawei's mobile phones was UFS or EMMC has caused a great deal of trouble. Many people want to know what kind of storage device their cell phone. Xiao Bian today gives you three ways to quickly identify the phone's storage specifications.

The first method is to install a "terminal emulator" (download address: http://) on the mobile phone, and by outputting the relevant code in the window of the software, it is possible to return information related to the specifications of the flash memory chip of the mobile phone.

For example, type "ls /proc/fs/*" (note that there is a space between ls and /). If the returned result is a string beginning with "mmcblk", then congratulations, the flash media used by your phone is eMMC (now mostly version 5.1) is a patent for low-end mobile phones. If the result returned is "sd", then UFS media represents higher storage performance.

Enter "cat /proc/scsi/scsi" (there is also a space between cat and /) in the terminal emulator. If your phone uses UFS flash, it will return a string of characters, followed by Vendor. The Flash brand, the character behind the Model is the specific model of the flash memory. If your phone is eMMC flash, typing "cat /proc/scsi/scsi" will not return any results.

A specific version of the flash memory can be obtained by searching the browser with a specific type of flash memory as a keyword. For example, "KLUCG4J1EB-B0B1" this Samsung flash memory corresponds to UFS2.0 (Samsung flash B1 ends with 2.0, C1 ends with 2.1).

The second method is also detected by software, but the display result is more intuitive. Download address: http://pan.baidu.com/s/1i5uX6sP or public number reply message "Check storage" to get the download link, after the download is complete.

After the app is installed and running, the app can return test results in a matter of seconds, knowing exactly whether the phone is EMMC or UFS storage specification.

The third method does not even require software installation. First, find a file with a larger capacity, such as a TV show movie, copy it to the phone, and then copy any file on the phone to the computer in the copy. If it can be copied at the same time, Reading, it must be UFS storage, if the prompt is wrong, it must be EMMC.

This method is actually based on the working principle of UFS and EMMC to detect, EMMC storage is half-duplex, can not be read and write operations at the same time; and UFS is designed to be full-duplex mode, which means it can be at the same time When you read and write at the same time, do you understand it?
