I, as almost everyone else, had major issues with the new firmware update. I spent over 2 hours on the phone with tech support and they finally decided to replace my device. Once the new device arrived, I did some testing. Here are the results…
Configuration: Out of the Box - Firmware 3.01.04-139
Using FreeFileSync to copy 1669 files, 748 folders, 232 GB over GB ethernet connection to a created Public share with Media turned off
Total Time = 1:15:13
57.9 MB/sec
Configuration: Updated Firmware 4.00.00-608 and did Factory Reset

Of course, your mileage may vary.
I am going to continue to load the device up and check performance.
