Excellent NAS. I have plugged in four 8 TB HDDs and configured in Raid 5. The NAS box is almost noiseless and cooling is effective with temperatures remaining steady around 40 deg C. Transfer speeds are rock steady at 110 MBps +
Using this from almost a year now . Bought it from market . Using this on raid 5 configuration. Have installed 2tb wd red drive in each bay ...making it 8tb system ....enough for my requirements. Using this as Plex server also . Till now no issue . WD Warranty is easily Available in India ...that why I opt for this instead of synology. Plus it has higher configuration than synology in same price slot .Auto back up my iPhone via wd app is a big plus .
