Incredibly fast hardware - a very nice upgrade from my previous NAS.Reviewed in Canada on 29 December 2017
I can obtain speeds very close to theoretical limit of 1000Mbps (gigabit speeds).
Testing was performed over approximate 35m Cat6; switching is GS-724T; router EdgeRouter Lite (gigabit network); normal sized packets
1000Mbps / 8 = 125MB/s (direct conversion of units)
but you need to take into consideration data overhead
and testing revealed 118MB/s read and 118MB/s write
which are amazing speeds
The first image was a 5TB Toshiba x300 drive (7200RPM); one drive
The second image was a 3TB WD Green drive (5400RPM); two drives (Spanning)
I decided to stay with the 3TB WD Green drives as I had two of them and I could populate both drives bays.
Why WD Green (WD's Eco line) instead of WD Reds (designed for NAS)?
If WD thought it well enough to populate their lower end NAS/External hard drives devices with WD Greens then it is good enough for me (the two WD Greens I pulled from older WD NAS/External hard drives).
You can configure the drives as RAID 0, RAID 1, JBOD, Spanning.
Lots of options and a few apps but am using the device primarily just for storage (turned most of the apps).
Very stable - no compatibility issues.
Able to become your network's Local Master Browser (excellent WD!)
To comment regarding one user's review that he couldn't use this as a hotswap enclosure - this and many other NAS DEVICES ARE NOT DESIGNED FOR HOTSWAPPING. The unit is a linux based unit with the HDD formatted with EXT4; don't expect to remove a HDD and place it into your computer and hope to see the data unless you absolutely know what you are doing. If you don't know what you are doing you have a very good chance of permanently destroying your data.
Data transfer WILL slow down significantly if you transfer lots of very tiny files - this is a known issue with many NAS devices and is not limited to WD.
Fast, reliable piece of hardware - very stable, and solid piece of engineering.
