I have a NAS and a PC connected via a gigabit switch and both the NAS and the PC have gigabit network cards. I used LAN Speed Test to see the transfer speed and got a rate of 137 MB/s. That's megabytes per second not megabits.

Is that even possible? I thought the max transfer rate over gigabit is 125 MB/s? How am I getting this higher rate?

Bug in the benchmarking software? – Isaac Rabinovitch Oct 24 '12 at 4:37
14 seconds is not a very long test... – Chris Nava Oct 24 '12 at 5:19
Yeah I transferred a 200 MB test file and it took 14 seconds. I did it several times. I thought this software was pretty accurate according to reviews. – Aseem Kishore Oct 24 '12 at 5:22
I've not seen a mechanical hard drive exceed 100MB/s. Unless this transfer involves RAID or SSDs on both ends, the results must be erroneous – cloneman Oct 24 '12 at 5:24
I'm not sure what your benchmark software is doing, but 200MB packets don't make very much sense. – David Schwartz Oct 24 '12 at 5:44
