February 9, 201214 yr I'm new to unRaid and have setup my first server. I have 2 2TB USB drives full of media that I want to transfer. I have a gigabit network but I started moving files off of one of the drives and 24 hours into the transfer it's only about 22% done. Is there a way to get unRaid to recognize an external USB drive without transferring everything over the network?
February 9, 201214 yr likely still wont be any faster since you are limited by the USB 2.0 bus speed. maximum speeds for the interfaces involved. SATA2 3.0gbps Gig-e Network 1.0gbps USB 2.0 480mbps, or .48gbps. take those #'s and divide by 8 to see the speeds windows reports mb = megabit. MB = megabyte (windows). 8mb=1MB. as you can see, USB is your bottleneck and you have no way around it unless you crack open the cases for the external drives and mount them internally to the server.
February 9, 201214 yr one more thing to drive the point home. on the weekend i transfered 1.2TB of data from one computer to the server over a gig network and it took 6hours @ roughly 30MB/s.
February 9, 201214 yr Author Thank you for the replies. I think I may actually end up opening the cases and just attaching them internally. I disabled the parity drive to help speed things up a bit but it's still taking a significant amount of time and isn't even 50% done (and I have 4 more USB HDs to go through).

That's why I like using a cache drive. I can transfer the content over my network at 3 to 4 times that speed or one third to one quarter the time. Then the cache drive can then transfer it to the array over night.

I disabled the cache drive (its only 160gb on my system), left the parity drive on and started the copy using TeraCopy.
