Over the years I have purchase a couple of the low cost USB NAS solutions that Linksys has come out with. These units use an ARM processor and a mini linux kernel. For the most part they work but, they are slow and if I try to un-tar a file on the unit back to itself it will lock up. I thought I'd move the drives to OpenFiler and away from the ARM processor. I setup OpenFiler, configured it with a multiport USB card and connected a new drive to it. Then I started moving files to it, the performance was below the charts. The ARM units were typically twice as fast as OpenFiler. The OpenFiler system was practically idle from what I could see in top, accessing the drive from the system had some issues as well. Does anyone have any experience with OpenFiler and USB drives or performance tuning it? Thank
