Speed. It is all about speed. The USB 3.0 standard is, theoretically, about 10 times faster than its predecessor, so moving files back and forth should be much, much less time consuming. Sure enough, we tested the USB 3.0 transfer rates using a Samsung Galaxy Note 3 and the results we got were positive, at least for the most part.
The most significant speed bump is observed when large files are being transferred – movies or videos recorded with the device itself. Copying such files from a PC to a Galaxy Note 3 is about 2.4 times faster when USB 3.0 mode is enabled. When a lot of smaller files are being copied or written, however – files like music or photos, which are usually around a few megabytes in size – then the benefit is not as profound. As a matter of fact, files of under 1MB in size take longer to copy when USB 3.0 mode is being used. Thankfully, most users are not likely to ever find themselves in the latter situation.
Now, you’re probably wondering why we could not achieve the aforementioned 10-fold data speed increase. Well, that’s because this rate depends on a number of other factors. One of them is the storage medium which data is being read from and written onto – our computer’s SSD drive and the smartphone’s internal memory, in this case. Obviously, file size has an effect on data speeds as well – the smaller the file, the longer it takes for it to get transferred.
