Synology DS120j vs DS119j NAS Drive

The New DS120j or the Old DS119jWhich Budget NAS deserves your data?

With Network Attached Storage (NAS) being so popular these days, it is completely understandable that in order for everyone to buy one, some more affordable NAS solutions need to be developed. As much as you want a NAS that can do EVERYTHING, it can be rather disheartening to look at a price tag that is literally in the thousands of pounds and realise it is vastly outside your budget. So the next time to look at what you can afford and that is where the Synology J series comes into play. As already discussed in previous NASCompares articles, the Synology J series is designed to be cost-effective (not cheap – very important). That means that the hardware you are buying, though comparatively lower than those in the bigger Intel-based, Gigabytes of Memory and 10GBe ranges, still arrives with standard specifications that will get smaller, standard NAS tasks done. Until last month, the most cost-effective J series NAS that Synology had available was the £80 DS119j (released in late 2018) and it proved to be very popular indeed, with a price point that meant that it and a 2TB Seagate Ironwolf NAS Hard drive came in at just over £170 ex.VAT. The newly available Synology DS120j NAS is the very latest cost-effective unit to be released and many people are wondering how it compares with the 1 years older model, it is worth an upgrade, should they buy the older NAS if it’s on offer, or should they buy the new model? So let’s compare the DS120j and DS119j from Synology.

What can you do with a cost-effective NAS? Does budget NAS mean budget results?

Low cost of data what is the price of Budget data storage enclosures and drives

It is completely understandable that many would be nervous buying such low price NAS devices as the DS119j and DS120j. They have been designed to be incredibly affordable and all too often we worry that something is too cheap. I referenced the comedian Dave Gorman a while back with he talked about cheap and too-cheap. For example, you see a ticket from the UK to the U.S. for £180 and you “wooooah..that’s a bargain, I will buy that”. If you see the same ticket buy for £9.99, you think “that is TOO cheap, the plane must be made of paper, it will never come back!”. In essence, people doubt that they can’t possibly afford to go that low and still provide the service promised. So what exactly can you do with a Synology DS120j and DS119j NAS? Before we compare what is better or worse about these NAS server devices, let us look at what is the same:

Synology DS218J 2-Bay NAS for 2017 and 2018

  • Both NAS arrive with low power use ARM processors and White plastic compact chassis, the result is reduced power consumption, noise and low temperatures
  • Both units can steam media over the network and internet upto 1080p, however, you cannot transcode (transcoding means you change the file size, format, resolution and more so it is better suited to the destination device, such as an iPhone or Android tablet
  • Both NAS devices are DLNA certified, meaning you can access and browse the NAS via your Smart TV, Apple TV, Chromecast, Roku, PS4, Xbox One and many other network available media devices
  • Both devices arrive with the Synology DSM software that arrives free, however, it is a more scaled-down use version of the software when compared with the likes of the DS220j and DS420J NAS (due to the hardware being less powerful and Synology removing applications and functions that the DS120j and DS119j just cannot support. Though there are still lots of apps, access everywhere solutions, easy functionality and an intuitively designed user interface at your fingertips
  • Both the DS120j and DS119j can be accessed by a multitude of iOS, Android and Windows mobile applications such as DS File, DS Video, DS Photo and DS Music, all available free
  • Both DS120j and DS119j arrive with access to the application ‘surveillance station’ (with the FREE Synology surveillance software – Review here) to set up your own surveillance set up at home, a shop or a busy office. They both arrive with two camera licences and providing live, worldwide, permission and encryption-based access to upto x5 cameras
  • Both arrive ready to go (just add one or two Hard Drives) and compatible with Windows, Android and Mac systems, as well as acting as a bring between them as needed
  • Both can host an easy to set up iTunes server (just install the free app in the App center) to stream media to your audio devices over to DLNA devices in the network
  • Both units can be used as mail and business servers, as well as providing CRM and CMS systems via apps in the app centre such as SugarCRM
  • Both units can be set up as standalone download servers, allowing you to set up tasks and schedules for downloading files and in BT, NZB, HTTP, FTP and RSS as you need. Never miss a Podcast or Broadcast ever again

Synology DS119j NAS Review

With the release of the new DS119j NAS, when it comes to buying your first network-attached storage device there are several reasons why the Synology range appeals to many. With a diverse range of hardware and storage options across a wide series of uses, as well as an impressive range of first-party applications, Synology has fast become one of the biggest names in the NAS. However, so many users have one tiny problem with most Synology devices, namely the price tag. In terms of overall price, you will find that a Synology NAS typically is around 15 to 20% more expensive than most other brands with the same hardware (we will leave software out of the equation for a bit). Added to this is the fact that most buyers looking to buy their first unit are nervous in spending large sums of money on a largely unexplored area of technology.

DESIGN Much like the previous DS115j release, the chassis is plastic in design. Although this is not favoured by everyone, I would say that it does massively reduce noise and does bring the price down considerably. Additionally, it is very modern and sleek.
FEATURES For a NAS arriving at such a low price point, there is no denying that it gives alot. Arriving with a slightly slimmed-down version of the DiskStation Manager Application software (due to that 256MB of memory). It supports all the standard applications regarding backups, surveillance, DLNA and more. However, it will support them only to a streamlined degree.
PERFORMANCE As a 1-Bay NAS server, there is no denying that you are getting ALOT for such a small comparative price tag. In terms of performance, you will most likely see around 80MB-100MB of Read and Write. Plus you will get 1080p DLNA support, Surveillance, 2-3 Backups at once. Not going to blow your socks off, but for low-end users, it will be more than sufficient.
VALUE There is no avoiding it, THIS is the lowest priced Synology that you can buy right now with this kind of hardware and for those looking to dip their first toe into the world of NAS or to get a low-end network backup, you will struggle to find better!

Luckily Synology has already addressed this problem before with the inclusion of a budget range of devices that serves as a fantastic introduction point to network-attached storage and the Synology Diskstation Manager (DSM) system software. The latest entry into this series, known as the Synology J range, is the brand new Synology DS120j, a single hard drive cost-effective network-attached storage device for desktop use. With a price point at just around £85-90 without VAT or hard drive media, you are looking at an impressive solution for those wanting their first NAS, yet not wanting to spend too much. Today we want to review this device and let you know if this surprisingly low price Synology drive can still deliver the promises of Synology and DSM 6.2. Ultimately, we want to work out if this device worth your money and your data.

DESIGN There is no avoiding that it looks plastic and only available in white.
FEATURES The 256MB of Memory is going to be a real limiting factor for many users and a tough pill to swallow paired with a dual-core ARM CPU at 64bit – it will be tough to get the most from that CPU.
PERFORMANCE You will hit a glass ceiling VERY early on in terms of speed and you will most likely outgrow the device before the warranty expires. Luckily you can still use the device as a network backup for your next NAS and you can still return on your investment.
VALUE If you are looking for a NAS that will perform for multiple users at once, playback 4K, Support RAID and Multi-drive functionality and more modern network functions – Maybe look at the DS218 or DS218+
synology DS216J Review Score Rating
Although this device will only cost you less than £175 including TAX and a 2TB hard drive, it can still perform the bulk of the standard tasks that are available in modern NAS and if you are looking for a universally supported DLNA or backup device, this is the one for you. Though definitely not aimed at the NAS experienced or 2nd-time buyers, or those looking for a solid foundation to build a business around, if you are looking for a network-attached storage device to act as a network backup or just want a simple nice to do basic tasks such as media and protecting the data on your other devices, I recommend the Synology DS119j NAS.

Synology DS120j NAS Review

Below is what we said about the Synology DS120j NAS when it was released back in late 2019. Ok, so let’s discuss the elephant in the room – let’s talk about the internal hardware of the Synology DS120j NAS. Because of the remarkably affordable price tag of this device, the internal hardware is pretty low and although it is 100% better than the DS119j in memory, it is still the same low power CPU in general terms compared with other Synology NAS. The DS120j arrives with a Marvell Armada 3700 88F3720 – and a mere 512MB of memory which, although double that of the DS119j, is still pretty low by modern standards. So not to put a final point of it this, NAS only supports a more streamlined version of the DSM 6.2 software from Synology and it’s applications. That said, I was still very surprised at the number of apps that is did arrive with. It will certainly support features and functionality such as DLNA media playback too network devices, multiple backups from PC/Mac systems, multi-user file access and sharing folders. It even supports desirable Synology first-party apps such as Synology Drive, Synology Moments (particularly impressed by that one) and even surveillance station.

DESIGN – Very simple Plastic design but still very much befitting of a NAS and more appropriately Mac environment. Plus the unit will not generate enough heat for the plastic to be a problem as also keeps production costs low enough to keep this NAS at around £100 without the drive.

FEATURES – The Synology DS120j may well be low on the NAS hardware front but it can perform and provide most of the standard file-based tasks that other NAS units can do outside of the J series. You can forget about the likes of Plex Media Server transcoding, but you will have reasonable video streaming locally as well as Synology DSM NAS OS abilities to create download tasks, backup USB drives, backup migrated storage and DLNA media distribution.

PERFORMANCE – Don’t expect the ground to shake with its awesome power! But again, it performs slowly, yet comfortably at those low-end file-based tasks and is definitely the NAS server of choice for those looking for Mac Backup images with the likes of Apple Time Machine. It should not be overlooked that though the 512MB of memory is remarkably small by modern NAS standards, it is still twice that of the 256MB available on the DS119j.

VALUE – For the cost, the Synology DS120j is a nice starter NAS that is is one for the first time network Attached Storage user or those with simple, small file tasks. I would recommend this NAS with a couple of Large Hard drives like the WD 4TB Red or Seagate Ironwolf 8TB. For those on a tight budget, skip NAS drives entirely and go for the Seagate desktop drives, though this is not advised for mission-critical data.

DESIGN – NAS Hard Drives are installed internally (no tray on the Synology DS120j) so a tiny (and I really do mean tiny) amount of physical installation is required.

FEATURES – You are heavily limited on a software level with apps and miss out on almost all the top Synology first-party apps released in the last 3 years.

PERFORMANCE – The DS120j leaves very little room for growth or evolution – You get a solid NAS that performs ploddingly in the background – but 3 years down the line it will not have grown into your dream NAS.
VALUE – Buy this NAS for tasks that are smaller and more manageable and don’t make plans for expansion. this is a NAS for today and even for tomorrow… just not for next week!


Although this device will only cost you less than £175 including TAX and a 2TB hard drive, it can still perform the bulk of the standard tasks that are available in modern NAS and if you are looking for a universally supported DLNA or backup device, this is the one for you. Though definitely not aimed at the NAS experienced or 2nd time buyers, or those looking for a solid foundation to build a business around, if you are looking for a network-attached storage device to act as a network backup or just want a simple nice to do basic tasks such as media and protecting the data on your other devices, I recommend the Synology DS120j NAS. Just make sure you have an off-site backup in place (such as a study external USB drive or a third-party cloud space with which to back up your data to periodically via cloud synchronization). Lastly, as much as I recommend the DS120j, it is worth remembering that it does not multitask especially well (due to that more modest CPU and memory), so sometimes you will need to be patient.

Synology DS120j vs DS119j NAS – Specification Comparison

It is pretty clear early on when looking at the official specifications sheets of these NAS that the newer DS120j NAS is incredibly similar to the DS119j, but still features a little extra software performance stats, but why is that? Well, that largely comes down to the doubling of the memory in the newer device. Below is how the two 1-Bay NAS compare is hardware specifications and support:

      6 thoughts on “Synology DS120j vs DS119j NAS Drive

      1. how well would this work for streaming ripped CDs and DVDs? (not blu-rays). i have a giant home-built NAS but it’s loud and power hungry, so i leave it off most of the time except when i’m making a backup or leafing through for an old picture or something, but it would be nice to have something small on all the time to access my music and movie collection from.

      2. Hi NasCompares – i know you have tried gaming from NAS before, but that was 1 user (which is you) accessing the NAS currently. What if 4-6 person accessing the same file, the same game, what component usage will be increased? is it linear? because i have tried before VHD inside Freenas, with 2 person accessing Fortnite, it runs well. Unfortunately, cant test more user than that since i have limited space and budget to do that testing. The Freenas run on my old Lenovo g500s. Looking to buy a better nas, but havent decided which one and need some more info
