Speeding up rsync over smb

I started to rsync a mount smb share to a local raid partition yesterday evening. After 12 hours it has copied like 30% of 400 GB... the average speed is 4mb/s, but I connected the both machines directly over ethernet, should have 100 Mbit/s connection...

Any advice how to speed things up?

Edit: the files are many many images and indesign files, creative work!

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


Identifying the actual NAS product in addition to the hardware configuration would help in determining what to expect.


Copy speed depends more by disk speed (which raid? hardware o software? SCSI, SAS, SATA...) and less by network speed. Usually the bottleneck is always disk side.

  • the nas is a MaxData SN40 und the raid controller is a m5015 in a IBM x3500 server with a RAID5 6 SATA drives! – Tronic Jul 30 '10 at 10:35
