What are the differences between MTP, PTP and USB Mass Storage protocols?
When we connect our Android smartphone to PC, we usually have three options:
– USB Mass Storage
Now let’s see what are the features, advantages and disadvantages of these options.
MTP on Android (Media Transfer Protocol)
In the latest and greatest versions of Android , MTP or Media Transfer Protocol is a protocol that is used by default to communicate between Android device and PC . When connected via MTP, our smartphone is called a “multimedia device” for the operating system. Therefore, we can use it with other applications such as Windows Media Player or iTunes.
In this method, PC has no control over the storage device, but its behavior will be exactly the same as the client-server communication behavior. The following are the steps that we usually do after establishing a connection between an Android device and PC :
– First, we connect the Android device to PC .
– Then open the storage memory.
– After that, the Android device sends a list of its files to PC .
– At this point, PC sends a request to download the file.
– Then, the Android device sends a copy of the file, this file is downloaded via a communication cable on PC .
– Now a list of files is forwarded and the connection is closed while waiting for a response.
Send a file if you need to:
– A request is sent to transfer the file.
– Android device accepts this request.
– After that, the file upload process begins.
But the point is that the MTP protocol speed is relatively slower than the speed provided by the Mass Storage protocol, although it also depends on the device connected to the PC .
In addition, the protocol in question has other negative points. The MTP protocol is both less stable and less compatible than Mass Storage, for example, it is not very compatible with systems running Linux. Because MTP requires special drivers to work. This protocol is also slightly incompatible with other types of operating systems such as MacOS and causes problems.
PTP on Android (photo transfer protocol)
PTP connection or Picture Transfer Protocol is the least used by Android users . Because when the user selects this option, the Android device is displayed as a camera on the PC. In general, it supports MTP and PTP protocols simultaneously when connected to a PC.
In PTP mode, the smartphone behaves like a camera without MTP support. This mode is only recommended if the user wants to easily transfer photos to PC without the need for software or other tools .
USB Mass Storage on Android
Undoubtedly, USB Mass Storage mode is one of the most widely used ways to connect an Android device to PC . This mode is very simple and fully compatible. In USB Mass Storage mode, the device appears on the PC as USB storage or external hard drive , and the user can work with this storage space without any problems. If the Android device has an external memory card, this memory is also displayed as a separate storage device.
The only major problem with connecting your Android device to PC in USB Mass Storage mode is that data will not be available on your smartphone , and this problem will persist until the storage space is removed from PC . Some applications may even have problems accessing this memory.
The latest versions of Android have increased the security of data stored on smartphones and tablets, and on the other hand, have eliminated the issue of compatibility with this type of communication.
