I have set up 3 Seagate St3000dm001 drive in 6 - bay raid enclosure using USB 3.0. The problem that I am facing with the same is that when I am copy several files over 400 mb then I donít know why the process gets freeze for some seconds after copying the first file and before starting the other. I am not having any issue when I am transferring single large files it just happens for multiple files. Is this an issue with the Seagate St3000dm001 drive? Has anyone else faced the same or the issue is just in my case??? Any ideas?
