Choosing the Right 4K Fully Featured NAS – DS218+ Vs DS918+?
Back in September and October of 2017, Synology NAS (currently regarded as the top NAS brand at the moment for the home desktop, SMB users and more) decided to release almost their entire desktop diskstation NAS series at once. Understandable this caused a great deal of confusion for many NAS buyers as suddenly they were no longer choosing between two or three devices, but now over ten to twenty (if you factored in the older releases too). I still don’t think this was a fantastically smart idea and only time will tell if this gamble paid off for them, but after the dust settled, two particular Synology NAS devices were more popular than all the others – the Synology DS918+ 4-Bay and the Synology DS218+ 2-Bay. Somehow these two NAS servers had really appealed to NAS shoppers because all the other NAS devices released were either too expensive for the hardware, or too lacking in hardware too start with to provide the performance NAS users needed. However, despite the big margin of price and hardware difference between them, most users choose either the DS218+ for its great Price VS hardware or the DS918+ for its supreme power, performance, long-term use and expandability. But today we want to figure out which NAS device is right for you.
The DS918+ NAS and DS218+ NAS? What can both do?
Despite their differences, there are a number of things both the Synology DS918+ and DS218+ NAS can do. With around £200 price difference between them, if you need your NAS to only do one or two of the things below then congratulations, you may well save yourself a lot of money! Take a look:
- Both units feature Intel x86 CPUs and plastic compact chassis, thereby reducing power consumption, noise and heat generated
- Stream and transcode on the fly (so, live) 1080p HD or 4K media – though performance in greater on the DS918+ and it can also transcode dual streams of 4K too.
- Both units are DLNA certified so can be accessed, browsed and played from by popular DLNA devices, such as Amazon Firestick, Chromecast, Apple TV, Bose, Sonos, iPads, etc
- Both are multi-bay, RAID enabled devices NAS devices that support JBOD, RAID 0, RAID 1 and SHR, as well as supporting the very latest SATA based 10TB and 12TB NAS Hard Drives from brands like WD, Seagate and HGST. However, the DS918+ also supports RAID 5, RAID 6 and RAID 10
- Both devices run on the DSM 6.1 (6.2 in beta) software that arrives free on the device – lots of apps, access, functionality and intuitively designed software at your fingertips
- Both use and can be accessed equally by a multitude of mobile applications such as DS File, DS Video, DS Photo and DS Music available on iOS and Android
- Both units support use as a surveillance station (with the FREE Synology surveillance software – Review here), arriving with two camera licences and providing live access to at least x20 IP Cameras via the DS218+ NAS and upto 40x IP Cameras on the DS918+
- Both units are completely compatible with Windows, Android and Mac systems, as well as acting as a bring between software platforms to share and distribute files
- Both can be used as a comprehensive iTunes server
- Both units can be used as mail and business servers, providing excellent CRM and CMS systems
- Both units can be used as download stations, allowing you to set up tasks and schedules for downloading files and in popular formats such as BT, NZB, HTTP, FTP and more
What are the Pros and Cons of the Synology DS218+?
DESIGN – I absolutely love this new chassis. Robbie on our YouTube channel, when asked to compare it with the DS216+ case, described it as comparing the new Robocop movie with the older one. Much more modern shape and design, a good mix of sharp edges with all the curves in the right places
FEATURES – On a hardware level, you are going to be hard pushed to find a better 2 bay in this price range. Only the Synology DS718+ gives you better hardware options, but at a price of just £280+ without VAT, this is hard to beat
PERFORMANCE – Featuring a great J series CPU from intel in Dual Core and 2GB of memory, this unit can perform all of the very latest applications from synology in DSM 6.2
VALUE – Synology has really turned a corner on their NAS series with this upgrade to the DS218+ flagship home two bay NAS. This is a worthy successor to the DS216+II and highly recommended.
DESIGN – Still features that odd removable front panel, instead of lockable trays.
FEATURES – Just one LAN port mans that link aggregation is not supported
PERFORMANCE – That dual core CPU, though an x86 chip that is highly suitable as a plex media server, is just a little underwhelming for creating even a single standalone VM use.
VALUE – If you reduce the size of your hard drives for this NAS by even 1TB each, you can afford the more powerful DS718+
What is the Synology DS918+ Diskstation NAS and Why should you buy it?
Released in mid-September 2017, the Synology DS918+ NAS is widely regarded as one of the most game-changing devices Synology has released yet. Featuring pretty impressive hardware specs inside:
This feature alone almost completely justifies the extra £100 spend. However given the 4GB of DDR3L over the 2GB that the DS718+ arrives with, as well as the 2 extra Hard Drive bays (which you do not need to fully populate from day one – either of these devices can run on a single HDD if needed), for me going for the DS918+ is a no-brainer and wins.
What are the PROs and CONs of the DS918+?
So, what are the advantages and disadvantages of the DS918+:
DESIGN – With a newly created chassis released with improved ventilation, but still managing to keep compact (even introducing new hardware inside) this is by FAR the best Synology design yet. A welcome improvement to the old DS916+ chassis.
FEATURES – The Synology DS918+ NAS will do it all. If you need a NAS to watch and transcode 4K, Run several VMs, Apple time machine backups, host a plex media server, run an iTunes server, run a business from, run surveillance cameras over the network, provide a CRM and CMS system, as well as host several websites – The DS918+ is the NAS server for you
PERFORMANCE – Easily one of the best performing Synology NAS devices available for home and small business users. Also if the default hardware isn’t enough, this is the easiest to upgrade, featuring RAM upgrades and NVMe slots
VALUE – This could possibly be the best NAS of the year. We still have a couple of months before we can truly decide, but for this price and the HUGE amount of software and hardware option in the price, threshold makes it irresistible.
DESIGN – The two rear fans, though fully controllable, cannot be completely switched off and this may annoy some people. However, any noise they make on their lowest setting is still lower than the HDD you have installed.
FEATURES – Although it can do many of these tasks at once, if you need to do ALL of them at once, you will need a solid Intel Xeon at the least.
PERFORMANCE – The Only fault I can find is that there is no 8GB Default version available to buy, as you found with the DS918+ (8GB).
VALUE – It is a shame that there is no 8-Bay option with this hardware – as the DS1817+ is rather disappointing by Comparison
Should you buy the Synology DS218+ or DS918+ NAS – Conclusion
As hard as it is to decide between the Synology DS918+ NAS and DS218+ NAS in terms of money/cost, you really have to try to remove this as a factor when deciding between them. Whichever Network attached storage device you buy, you are going to want to make the most of it and justify the purchase for today and for the years that it will be working in your home and business life. That is the key difference between these devices. The Synology DS218+ provides an excellent performance on most common NAS tasks and applications and will suit those looking fora NAS for both them, their family and light business use for up to and above 3 years. The Synology DS918+ provides you all the same functionality of the 2-Bay, but in much, much more quantities. As well as supporting many business class applications and hardware advantages such as Virtual Machine use, expandability with the DX517, a longer warranty and the performance upgrade of dual NVMe SSD slots now or at a later date. The DS918+ is the NAS solution for those that want a 5+ year NAS solution for their home and/or business life.
