USB-3 file transfer speed indications
Posted: 2018/06/20 15:26:28
I'm running Centos 7 on an intel i7-8700 system with 32GB ram.
The drive is a GPT 4TB WD Elements with 2 partitions both formatted NTFS
I'm using NTFS-3g.
The copy is from partition 1 to partition 2.
I am using a USB 3 port with the supplied drive cable connected.
While trying to copy a folder containing files of between 1 and 2GB each up to a total of 140GB
I'm seeing wild fluctuation in reported transfer speed making estimated copy time impossible.
The variations go from 600KB/S to about 112MB/s Fluctuation is continual not from file to file.
Additionally stopping the copy and using the safe drive removal option reports it is safe
to remove the drive even though the drive is still active for more than 5 minutes more.
So the questions are:
Have I missed a config setting
is this normal
Has anyone else had anything similar etc?
TIA
