Review | Alternatives to DS218+?

DS718+ will be a more powerful option if you intend to use it for virtual machines, or more simultaneous users.

DS218 will be weaker option if you want to save money, but still be able to transcode some 4K (no Plex)

Review | What can I connect to DS218+?

Wireless Speaker Sonos

The great thing about Sonos is that you don’t need to pay for music subscription service. With the cheapest NAS at home like DS218+ or any other, you can have your backups done for all of your devices and still use your network drive as a Sonos music library. Sonos will connect to your NAS via your network and let access your provided music library. If you have little more of IT knowledge, you can even set up your Alexa or Sonos with Alexa built in to play music on your voice commands (“Alexa! Ask DS Audio to Play Music!”).

Casting devices

Nowadays it is so cheap to upgrade your old TV and make it smart. All you need is Google Chrome or EZcast alternative plugged into your HDMI port at the back of your TV. Now you have great functionality added to your TV to send a video file directly from your NAS to a TV. No need for wires and chargers and other mess. You can use your phone as a remote to go to your movies or family videos and cast that content on your TV during family or friend gatherings.


Amazon Fire TV

You may not have a smartphone, or you just simply prefer to control your content with a remote in that case Amazon Fire TV will be a great addon to get to your TV. It also plugs into your HDMI port and will play content from your NAS to a TV. No wires no mess.

nVidia Shield TV

It gets even better! If you want some more entertainment and all previously mentioned functions – nVidia TV is a great thing to get. You can use it for playing games and watching movies from your NAS. The greatest thing is – shield TV does video transcoding. So even if you have a cheap NAS with a weak CPU, in a combination of shield TV you can now automatically on the fly change video file size and format for a destination device. It is a great way to reduce network load and let older devices to play video content which normally was not supported on the device.

What is maximum capacity hard drive compatible with DS218+?

Maximum raw capacity DS218+ can handle is 24TB (2x12TB). That is storage with RAID0 setup, which offers maximum storage space and data writing speeds. A solution like this requires a backup plan in place. If disaster strikes, users will not be able to use NAS functions until data on it is restored.

WD is the very popular choice because they are quieter than other drives, due variable disk spinning speed.

Seagate is popular because of their rescue services and integrated health check shared between NAS and a drive

HGST is popular among IT professionals who need faster spinning disks with higher IOPS for faster data accessing rather than transfer speed.

Review |  Final Thoughts- should I buy DS218+?

DS218+ is the most popular NAS this year, because of its price/performance. It will do anything what modern NAS need to do at quite acceptable speed. It can be upgraded and expanded. It comes with amazing free apps. You can not go wrong with this choice. It is powerful enough to last next 5 years.
