Ever since people have gotten their hands on the Galaxy Nexus, there have been reports of the device not supporting the USB Mass Storage (UMS) protocol that allows you to mount the internal memory on your computer. Since this is the first Ice Cream Sandwich device, this peculiarity was attributed to the OS lacking the particular feature. But as Google engineer Dan Morrill explains, that is not the case.

As it happens, Ice Cream Sandwich does support UMS, it`s just that the Galaxy Nexus doesn`t. Instead, it uses MTP or Media Transfer Protocol, which is natively supported on Windows and commonly used by devices such as media players to sync with Windows Media Player.
The reason for this is simple. Unlike, say, the Nexus S, which has two separate memory chips, the 1GB internal ROM on which the OS is installed and where you can also install apps and the second, 16GB storage memory for all your other stuff, including apps, which is what gets mounted on the PC when you connect it through USM. The thing is, a memory can only be mounted at one place at a time. The memory on which the OS is installed is mounted on the phone, which is how the phone is working in the first place. To be able to mount it on the PC, the OS will need to shut down, like on the older Sony Ericsson phones.

On the Galaxy Nexus, they are using only one 16/32GB memory on which everything, including the OS is stored. This memory, as just explained, cannot be mounted on any other device. This is where MTP comes in. It allows you to transfer data just like on USM but without having to unmount the memory from the original device.

Google added support for MTP in Honeycomb and in fact most Honeycomb tablets use only MTP to transfer data to and from a PC. Technically, there is not much difference between MTP and USM. As an added bonus, you get to sync the device with Windows Media Player. On Mac or Linux, MTP devices appear just as any another USM device. Also, when installed in devices with multiple memory chips, Ice Cream Sandwich will automatically enable USB as the data transfer option, so no need to worry about that either.
