I’ve just purchased a WD MyBook Live Duo 8TB. I installed it according to the instructions and applied the firmware update MyBookLiveDuo 02.43.03-022. My Netgear gigabit switch shows it’s in 1000Mb/s mode, and the MBLD shows a green LED on it’s ethernet port.
I am getting horrifically slow copy speeds from this thing.
Using SyncBack to create a mirror copy of a 4TB drive, I am seeing 4MB/s copy speeds (average over 10 hours) and an estimated completion time of 12 days!
Well maybe it’s an issue with SyncBack. So lets try the vendor supplied WD SmartWare software instead. So after waiting ages for it to “catagorise” my files (I want everything backed up, so this was a waste of time) it started coping files at the blistering speed of… ~250KB/s!
I bought this drive to replace my 4TB Acer Aspire easyStore NAS. Now keep in mind that the Acer was a low-end, budget consumer NAS, purchased 7 years ago. On the same setup as the WDMBLD it gives 36MB/s. Almost 10x what the WD unit is giving me at best, and ~140x faster than what WD SmartWare backup is doing.
At the moment the WD MBLD is too slow to be of any use as a backup device for anything!

And the RAID0 array it was copying from:
