so assuming usb would use a similar amount of cpu (I have no idea how bad the usb drivers and vs. how bad the wemac driver is), one might push a whooping 20-25MB/s thru it... pretty much what you can get with usb2 anyway
<wooy>
dongs: for the previous question, my a10 is easily doing samba on 95 Mbits. I dont remember the cpu usage, but it was much lower than i expected.
<hno>
jelly-home, and maybe possible to get a bit more if you team two USB nics, one on each USB host channel.
<hno>
+ wemac
<hno>
Will be interesting to see how A20 manages gbit ethernet. Unfortunately I only have 10/100Mbit PHY on the A20 boards I have so can't test.

use a command like the following (make sure the path to the vmlinuz is right, and the last bit is where it will put it): mkimage -A arm -O linux -T kernel -C none -a 0x40008000 -e 0x40008000 -n 3.4-43.sunxi.1sunxi -d /boot/vmlinuz-3.4-43.sunxi.1sunxi /mnt/uImage

acki: I hadn't heard it had a 2TB limit but could have missed that I suppose. I'd have presumed it would handle 4TB (or larger whenever they appear) though I've none to try (stopped buying when the flood sent prices silly). but it does only handle one disk (or at least if you want to use more then one disk you need some hardware to connect the disks to that present them as one disk to the cubie)
