Hello,
I've been testing the Memeo software for backing up 2 pc we have to the TeraStation Live 2.0 GB NAS. The software seems to be a little slow. Plus it seems to hang on some files. Overall performance of the NAS seems a bit slow.
Make sure that you have the latest version of the firmware on the NAS, you can find this at buffalotech.com
Also you can update your memeo version at Memeo.com
