check your USB cable, whether you have a slow usb1.1 printer or any such device connected to your pc at the same time as your transfer. Also are you transferring using mass storage or sync and connect. At time of you have hundreds of small files being transferred the speed gets bogged down too...

Connect the phone using mass-storage mode and reformat the partition like any other partition/drive?

This is also the reason the phone cannot access the filesystem while in USB storage mode, because it cannot mount a filesystem locally and over USB at the same time

Going FAT32 w/ 4096 cluster size indeed increases the speed up to some 20MB/s. This is a great find. Why the hell hasn't the device been properly formatted from the very beginning?

I checked mine (with Windows, chkdsk command), and it says 65536 B.

Yeah, 64KB and I never formatted MyDocs before. This must be the default factory setting.
I bet there are hundreds of people cursing N9's USB speeds not knowing this can be fixed.

Since a while my 16GB N9 has a USB transfer rate of 3-4MB/S, in the same conditions my 64 has a transfer rate of 20MB/S... Do you know what could cause that ?
Thank you,
