5.0 out of 5 stars Surprisingly good!
Reviewed in the United Kingdom on 28 July 2018
So I wanted to a NAS for a number of reasons, those included;

1. Plex for my media library.
2. Remote Virtual Machines to run Linux.
3. Backups for all devices at home.

Now my main concerns were processor power for Plex connected to my 43" 4k TV and ram for the virtual machines.

The first thing I did was upgrade the ram, ordered an 8GB kit at the same time as the NAS at £63. So that fixed any concerns over maxing out the ram, although I do recommend upgrading it as 2GB is not great you will probably get by if you are not running lots of apps, especially virtual machines.

The processor you can't do anything with, it is what it is. Now for Plex, it recommends a processor with at least a 2k pass mark for a single 1080p video stream. The processor benchmark is 1861, not optimal but handles it fine, the key is to avoid transcoding whilst you watch however that is beyond this review. Plugged into my TV through the HDMI port it performs incredibly well and everyone is happy with the quality.

Other than that the device has many apps and it's quite easy to install, keep up to date and understand when it needs to be updated.

I am using 2 3TB Western Digital Red drives in the unit, performance is good and in the 6 months since I set up the NAS it has been running without a single issue.

So overall and with 6 months of use in hand I can honestly say it has been a great purchase and my concerns around it being powerful enough for my needs very quickly disappeared. Helped of course with a ram upgrade.

If there is anything I could pick at it is that it can be quite noisy when you are sitting watching something on Plex. Not overly but noticeable.
