Initial rsync backup of large data slow to RAID 5
I'm using rsync to copy about 28TB of images to a 36TB RAID 5.
The source has SSDs and the destination has 6 8TB 7200 SATA3 512e drives in a RAID 5 configuration.
Servers are connected over a 10G fiber connection. They are the only two machines on the switch.
Source is CentOS 6.8 destination is Ubuntu 18.04.
I understand that the HDDs are not going to get the full 6GB/s write speed but I am currently only getting 65MB/s when I was expecting somewhere in at least the 200MB/s range.
The speed started at about 72MB/s then gradually increased to 83MB/s before falling to and maintaining 65MB/s over the course of about an hour. Currently the transfer is on course for 5 days.
This seems extremely slow. I was hoping for any suggestions on speeding this up or an explanation as to why it is so slow.
Command run:
rsync -a --info=progress2 user@sourceserver:/images/library/ /images/library
