I've been struggling to get decent USB transfer speeds with my Ubuntu computer, which I've asked about on the Ask Ubuntu site.
The answers there have helped me improve USB speeds overall, but it seems my phone is still much slower than other devices. For example, I can transfer to my Sony video camera at about 17.5MB/s, but transferring files to my Android phone (Samsung Galaxy 2 with ICS) is running at about 2MB/s.
How can I determine if 2MB/s is a normal transfer speed for my Android phone? In other words, what do I need to know about it's SD card (it has two, internal and external) specifications or other details in order to determine if I am getting the maximum performance or if it is still hobbled?
