Are you serious? Of course he is not running backups while performing a transfer speed test.
I wish I done my research prior to purchasing this product. This board and the internet is plagued with complaints about the performance. I was such in a hurry and was interested in the replication feature so I jumped on board.
Unfortunately, I have the exact same problem. Just purchased the Tera station pro and it rediculously slow. Unusable.
I have 4 other NAS devices on the same switch averaging over 75 mbps. The Terastation - 5 - 10 mbps.
I have updated firmware, changed cables, changed ports on switch and TS, change Jumbo frame settings, etc., even plugged into same port where existing NAS that is functioning properly - still no luck.
I agree that connecting to a PC is pointless and will prove nothing accept that the product does not perfom as expected when attached to a network.
