Podłącz laptopa po kablu i wtedy zmierz ile masz.

Ja bym obstawił że tak, w jednym z testów napisano:

The results we saw in our speed tests weren't impressive and the small file tests in particular were so slow we had to double check the NAS hadn't slipped into 10/100 mode. In our large file tests, it managed around 37MB/sec, with this speed dropping to 27.7MB/sec if we used the zPilot upload manager.

This is more than enough to handle several concurrent high definition streams, as our testing proved, but getting data onto the NAS, particularly large movie files, will take a fair while longer than other cutting edge NAS boxes, which regularly push the limits of hard disks themselves. In the small files tests, the NSA310 wasn't able to muster more than 12.7MB/sec - once of the slowest results we've ever seen. When streaming, it drew a
paltry 14W.
