Best Cheap Synology NAS – DS119j vs DS218j vs DS418j

Which Cheap Synology NAS should you Buy? DS119j, DS218j or DS418j

For those who are looking at buying their very first NAS drive, or are just looking for a simple network backup to support their existing NAS server, it can be a bit confusing. Synology has made efforts to separate their range of NAS server drives into different categories, in an effort to distinguish which one is most suitable for different applications. Very early on it becomes clear that the Synology J series is the most cost-effective range of devices in their portfolio, however, they have a very similar price and aside from a number of Hard Drive bays, it can be very hard to choose the best budget NAS in 2019. So, we have decided to compare the Synology DS119J 1-Bay, the Synology DS218J 2-Bay and the oldest of the three, the Synology DS418J NAS.

Synology DS119j vs DS218j vs DS418j – Value for Money

Because you want to buy a budget/cost effective NAS solution, it will be a big consideration for how much it will cost. Although these three NAS drives are by far the lowest priced Synology NAS devices you can buy in their respective ranges, when compared against each other, the price tag differences are pretty big. In fact, in the jump from 1-bay, to 2-bay and finally to 3-Bay, the price almost doubles each time! The Reason for this is threefold.

  1. The number of hard drive bays inside requires a better CPU each time to handle the RAID and communication of users to the larger media
  2. A bigger power supplier is needed each time to support these drives
  3. A bigger chassis is required to house the drives, as well as improved methods of cooling/ventilation to ensure maximum operational temperatures

Synology DS218J NAS


Synology DS418J NAS


1-Bay – £95+ 2-Bay – £150+ 4-Bay – £280+

Most users on a tight budget will want to appropriately divide their budget between NAS hardware and NAS Hard Drive storage (which need to be purchased separately). NAS Hard drives are roughly £30-35 per Terabyte (using Seagate Ironwolf NAS drives as an example), so you will need to factor this in. Although the DS119J is just £90+, it can only hold 1 hard drive, so you will either need to spend more on a bigger HDD (lose any RAID support too) or limit your long-term storage. Alternatively, you can buy the DS218J at £150+ and either spread the cost of storage across two HDD bays or just populate the NAS with 1 hard drive at the start and add another later.

Which leads me to recommend highly that you buy the Synology DS418J NAS as the best NAS for value for money. Although it is by far the most expensive NAS at £280+, you have the option of 4 hard drives and SIGNIFICANTLY better hardware inside that the others (will discuss more below). The clincher is simply the fact you can add hard drives over time, starting with a small drive to start and add bigger and better drives as you need over time. The DS218j and DS119j NAS both require you to add BIG hard drives at the start in order to ensure long-term storage and this ends up costing you more in the long run.

WINNER – Synology DS418J NAS

You just get alot more for your money. Also, it lets you leverage the cost of HDD and NAS Hardware much better overall.

Synology DS119j vs DS218j vs DS418j – Design

Despite the fact that all three Synology NAS is budget in price, all three have adopted the Synology style very well indeed. NAS drives are designed to be left on for days, weeks and months at a time, so both passive and active cooling is very important. All NAS feature multiple panels of ventilation and an active rear cooling fan, however, although the DS119j and DS218j are very similar (using a near identical white plastic chassis, non hot-swap drives and a single plastic rear fan), the DS418j is a very different device indeed in terms of design. All three feature dual USB ports (with USB 2.0 on the DS119j) and all three NAS feature the ventilated Synology logo.

5.01 W (hard disk hibernation)

16.9 dB(A)

Synology DS218j NAS

Synology DS418j NAS

184 mm x 168 mm x 230 mm

21.22 W (access)
8.97 W (hard disk hibernation)

20.6 dB(A)

Straight away, the DS119j and DS218j NAS are the more discreet of the two NAS, with the 1-Bay and 2-Bay being just under 3cm (29mm in fact) different in width. Both use a plastic chassis which lowers operational noise considerably and both are very discreet in terms of size. They even have very similar power consumption, despite their difference in price/size which is always a consideration for heat generation and long-term running. The DS418j, on the other hand, is much bigger in every direction, features a rather dated looking chassis (looks like a 70s cooking appliance but in black) and is a combination of metal and plastic. As much as I want to praise them for the design quality, there is no escaping that the DS418j is the least attractive of the three, is bigger, noisier and generates more heat (even despite those twin rear fans).

WINNER – The Synology DS218j NAS

Although it is very similar to the DS119j, it seems to do a much better job of making the most of that chassis design and makes subtle improvements over the smaller NAS.

Synology DS119j vs DS218j vs DS418j – Hardware

In terms of hardware, the DS119j, DS218j and DS418j have taken very different paths. We discussed the outside chassis etc earlier, but (like many things) it is what inside that counts! With each price/bay jump between them, the internal CPU power, memory storage and efficiency effectively doubles with each tier. See below:

The CPU on the Synology DS119j is painfully low powered. Do not be fooled by the fact it is a dual core, it is painfully low powered and even as a network backup drive, it still registers very low speeds indeed.  In fact, all three NAS are dual core in design and the DS218j and DS418j are very similar in clock speed (1.3Ghz and 1.4Ghz). However, the big, BIG thing to remember is the fact the DS218j uses a 32bit architecture CPU and the DS418j uses a 64bit architecture CPU. The difference here is very, very important, as more applications will be able to run on a 64bit processor, as well as it running smoother overall thanks to it’s improved floating point. This point is further enforced by the better memory present in the DS418j, compared with the other two. There is twice as much RAM in the DS418j than the DS218j, as well as 4x of the DS119j. But once again, it is quality that is important here – the DS418j uses faster DDR4 memory, whereas the DS119j and DS218j use DDR3.

WINNER – Synology DS418J NAS

It is very hard to ignore the faster, more efficient and capable CPU on the DS418j NAS, as well as the higher quantity and quality memory included with this NAS.

Synology DS119j vs DS218j vs DS418j- Software

As you would expect, given the superior hardware featured on the Synology DS418j, it has a much bigger coverage of NAS software in the Synology DiskStation Manager software than the DS119j and DS218j. However, though the DS418j is leaps ahead of the Synology DS119j NAS, it is only fractionally better in terms of software than the DS218J. The key advantages are only those where the additional two bays of storage play their part. Below are the key/popular software specs for the three NAS and how they compare:

Straight away the advantages of the Synology DS418j NAS are clear, but given it is almsot twice the price of the DS218j, you do not get twice the coverage of software/clients. In many cases, the DS218j gives you equal coverage of applications and users to the DS418j, however it is when you are running multiple apps at once or multiple users that you will see the main difference. The DS418j can suppot more apps/users at any given time than the DS119j and DS218j, thanks to that more efficent 64bit CPU and increased memory, as mentioned earlier.

WINNER – Synology DS418j NAS

Not a huge surprise, but it was closer than I thought it would be. You just cannot argue with the increasingly active user numbers and software support of the DS418j over the DS218j and DS119j NAS.

Synology DS119j vs DS218j vs DS418j- Verdict

Given that the Synology DS418j NAS won 3 out of 4 rounds in my budget NAS comparison, it would be easy to just say ‘buy it’, but the truth is a little more complex. Yes, the Synology DS418j is by far the best NAS overall, but for many users, the need for 4 bays of storage is just not needed. The same goes for the support of many more simultaneous users, as it might just be 2-3 users at most. If you are looking for genuine future proofing, then I highly recommend the DS418j. But if you just need a NAS to do a basic amount of everything, then the DS218j will serve you well. Finally, it is worth highlighting that although the Synology DS119j did not win any rounds, it is still a good simple network file server for Hyper Backup or Hyrib Backup sync (using RSync) or a low-level DLNA media server.
