Hi.
I'm using FreeFileSync to back up the stuff on my phone to an external hard drive.
When doing so the transfer rate was extremely slow - 2 mb/sec max. Often slower, as slow as 0.5 mb/sec at times.
Both my phone and the external hard drive are connected to my laptop using USB.
When I tested transferring files from my phone to the external hard drive in Windows — not using FreeFileSync, but rather just copy and paste from phone to hard drive, the transfer rates were around 20-30 mb/sec.
Does anyone know why transfer is so slow with FreeFileSync? I've been using FFS for years to back up my drives and I never noticed it being especially slow. I've donated a number of times. My donation version recently expired, so I'm using the non-donation version at the moment. Could that be the issue? Is there a throttle on speed for the non-donation version?
Why is file transfer suddenly very slow (under 2 mb/sec)?

This doesn't seem related. I don't have an issue with synchronization stopping completely.
I did some further testing and synchronization between external hard drives is fine. The issue seems to be only when syncing between my phone and a hard drive (for backing up my phone).
Somehow transferring files from my phone to a USB drive via Windows Explorer (normal copy and paste) is several times faster than backing up the files with FreeFileSync. I don't know why.
