MTP vs. MSC: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on March 9, 2024
MTP (Media Transfer Protocol) facilitates file transfer between devices, while MSC (Mass Storage Class) allows a device to be used as a USB mass storage.
Key Differences
MTP and MSC are two protocols used for transferring files between a computer and external devices. MTP, or Media Transfer Protocol, is commonly used for transferring media files such as photos, videos, and music. It allows the device to remain fully functional while connected, enabling users to access and transfer files without interrupting the device's operations. MSC, or Mass Storage Class, on the other hand, is a protocol that enables a device to be recognized as a USB mass storage, similar to a USB flash drive. When a device is connected using MSC, it is not usable until the connection is terminated.
MTP provides more flexibility compared to MSC. With MTP, a device can present a more abstracted version of its file storage to the host computer, and the device can continue to run applications and process internal tasks while connected. MSC, however, requires the connected device to relinquish control of its storage to the host computer. This means that the device cannot be used for other functions while it is connected in MSC mode.
One of the key differences between MTP and MSC is how they handle file management. MTP allows for more sophisticated file management capabilities, like accessing only a part of the file system or handling files that are in use. MSC, in contrast, gives the computer full access to the device's storage, but without the ability to manage files that are currently being used by the device.
In terms of compatibility, MTP is widely supported across various operating systems and is preferred for modern multimedia devices, especially smartphones. MSC is often used for simpler devices like USB thumb drives and older technology where complex file management is not required. MSC's simplicity makes it universally compatible with almost any system that supports USB mass storage.
When considering data transfer security and integrity, MTP provides a more secure environment. It prevents file corruption by ensuring that two sources do not simultaneously write to a file. In contrast, MSC mode can be more prone to data corruption if the device is improperly disconnected from the host computer.
