Transfer with USB 3.0

Hi Everyone,

I am trying to copy some video files from my Drobo 5N (via Ethernet) to an external Western Digital hard drive using USB 3.0 (on the drive and PC). The drive is a 4TB My Book. I am getting 11-12 MB/s transfer speeds. I don’t expect the full 625MB/s that USB 3.0 offers, but this is way too slow. I even connected the drive to a USB 2.0 port and still get the same speeds. What’s the problem? Can you please explain this? How do I correct this?

My specs are as follows:
Motherboard: Asustek P8Z68-V Gen 3
CPU: Intel Core i3 2100
Memory: 4GB DDR3
Graphics: integrated
OS: Windows 8.1

I appreciate any help you can provide.

Ron

  1. Sounds like 100Mbit ethernet not gigabit. 100Mbit ethernet will give a maximum of 11Mbyte transfer.... What switch or router are the two devices connected to?
  2. The limiting factor here is not the USB connection but the SMB network connection. On a really good network, with Jumbo frames enabled, you might get 30 MB/s on a large file. If your network is not so good, or your file sizes are smaller, you're going to get a lot less than that.
  3. Thanks for the replies. The main router is a Verizon FIOS router, then I have another router connected to that. The Drobo 5N is connected to the FIOS rotuer, the Windows 8 PC is connected to the second Linksys router. I haven't done any special configuration to the routers.

    How can I correct this to get faster transfers?

  5. Do both routers have Gigabit ports? In any case you would get faster transfer rates using FTP rather than SMB (Windows sharing).
  6. Depending on which version of the FIOS router you have it probably only has 100Mbit ports. You will get much better throughput using a GigE switch with all your devices plugged into it and a single uplink to the FIOS router. A netgear GS108 or equivalent will do the job.
  7. I am thinking the Linksys router is 100Mbit because it is an older router--maybe 8 years. How do I find out the specs of my FIOS router? I think the switch is a good idea. Also I have been toying with the idea of buying my own internet router rather than rent the FIOS one from Verizon.

    FIOS TV depends on the router for the guide and PPV. If you have FIOS TV you are limited to the FIOS router. The FIOS router they SELL is a wireless N and I believe has Gig-E ports.
  9. Guys,

    As an experiment, I tried copying the folder to the desktop. Then from there, I connected the USB 3.0 drive to one of the USB 3.0 ports and the transfer rate is up to 13.2 MB/s. For the most part it stays between 1 MB/s to 2 MB/s. This is a 25 GB folder I am to transfer. Can there be something wrong with the drive? Right now it is flat at 0 bytes as I write this.
