I have 3.4.3 firmware on mine, but have had the same issue for at least the previous two releases.
For me the pause problem doesn't happen every time I copy data to the NAS, but still quite regularly. Usually it will happen when nothing has been copied to the NAS for a while (at least a few minutes) and the file being copied is quite large (say 100MB or larger). After the pause has ended and I've copied a file, I can usually initiate a few more copies without the pause. But then waiting a couple of minutes (sometimes as little as a few seconds) and starting another copy the pause will occur again.

The recovery from that takes many seconds, and if the ethernet is glitching, that would explain the streaming interruption too.
Error correction ongoing on the disk drives? The NAS has to stop the activities, beceuase SATA drives are not responsive during these actions. Convinced we talked on that before - any insight on # dmesg or SMART counters?AdrianW wrote:But when it does hang no one can access anything on it for that period (which is now up to almost 30 seconds), the really weird thing is that when it hangs the LEDs for just drives 2, 4 and 7 will all blink in unison.

AdrianW wrote:I just checked the SMART reports for my drives and all of the error type raw values are zero for every drive, except one which has a value of 1 in a couple. (i.e. Raw_Read_Error_Rate, Reallocated_Sector_Ct, Seek_Error_Rate, Spin_Retry_Count,Calibration_Retry_Count,Hardware_ECC_Recovered, UDMA_CRC_Error_Count, Multi_Zone_Error_Rate, Load_Retry_Count).
So, I don't think the drives are at fault.
