What customers say about "Features"

Western Digital PR2100 Professional Series 2-Bay 16TB Network Attached Storage

Fast uploading, downloading, file transfers and access.
I have two 4TB WD Red 5400 rpm drives arranged in a 0 RAID array.
Download the app on your mobile device and access anywhere.
Fast transfer rate like local hard drive within intranet. Very stable. Easy setting.
Adding shares, users, and mapping drives also went smoothly. Copying files over was pretty fast.

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 PR2100 Professional Series 2-Bay 16TB Network Attached Storage

Transfer speed through Ethernet is good, with speeds nearing 100 Mbs for many transfers.
Well constructed, fast, quiet, and built using "RED" drives.
No issues with setup, it's fast and has a bunch of different apps available. Great LAN speed of this one.
Not enough outputs for comfortable use.
Backups are not fast. Hopefully the transfer speeds will improve.

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.
