What customers say about "Features"

Western Digital EX4100 16TB 4-Bay Network Attached Storage

Many RAID modes available including JBOD (Just a bunch of drives) for the most storage space. Good feature.
Great NAS with RAID options. I like this.
I was able to change RAID configuration very easily and the system chugs along in the background without any problems.
The setup of the device was fast and simple. Great features of this one.
The product has an intermittent issue (that I believe is related to the Drive Sleep function) which causes it to freeze.

Western Digital PR4100 Professional Series 4-Bay 16TB Network Attached Storage

Configured as Raid 5 – once the disk system builds it is very fast.
The unit was populated with 3 4TB drives and set up as Raid 5. Setup was straight forward and easy.
I put it all together, I put it in RAID 10. Plex server is up and running like a charm!
This is professional grade NAS, 4 disk drive, it supports RAID 0, 1, 5, 10, JBOD and spanning configurations.
With a Raid 1 set up, there is little risk that I will loose all the data.

What customers say about "Interfaces"

Western Digital EX4100 16TB 4-Bay Network Attached Storage

This is very fast with just Red drives. Good LAN ports.
The setup is easy, and it is screaming fast and quiet.
Easy to set up, certainly plenty fast for a home network, quiet and unobtrusive.
It runs nice and quiet and I do enjoy the LED display to let you know the status of the unit. Great speed.
Really fast. Plenty of features. Easy to install and connect.

Western Digital PR4100 Professional Series 4-Bay 16TB Network Attached Storage

The USB copy port on the front panel is very convenient and works great to copy external drives of any capacity.
Managing the device content within the LAN is fine. It can also be managed via WAN connection using myCloud.
The WD app is easy to use, fast, and stable. Great connectivity.
If you plug a USB 3.0 Drive in, the NAS locks up and crashes.
I thought it was weird that when I opened the box the LAN cable was not there.
