yes, 60-93mb on local network, I have a cisco dual band router with 450mb transfer rate both ways and it has a gigabit lan, I never did hack my pogoplug. I don't know how to do it, I can't find a good procedure on my pogoplug 4.
Thanks for info. The USB2 works fine for movie (even HD), but backing up >200GB drives takes a looooooooooooooooooooooong time. I've being waiting on a deal on the pogoplug 4 (with USB3 and sata).
Instructions for getting ArchLinux on the Pogoplug 4. [archlinuxarm.org]
Only if you're comfortable with ArchLinux though.
