The best Synology DS220J NAS Review

Although many may wonder what a NAS can give me that I can no longer do with cloud storage services, it is evident that a device like the one analyzed here allows you to have backup copies of your equipment and store content locally. 

Here is the key. You will be able to access the NAS device from any device and from anywhere in the world, with the certainty that what is stored is in your power, and the incentive that you can also set backup copies in the cloud of the most critical. 

Within the wide range of NAS devices that Synology sells, the J series represents the models with the best quality and price ratio. The one discussed here supports two disk drives with very low power consumption, designed to operate in 24×7 mode.

Finished in white, the Synology DS220J offers easy-to-manage Hybrid RAID protection home storage. Despite being an entry model, you can still enjoy the potential of services provided by DiskStation Manager or DSM as an operating system.

Design and build

The NAS format is extremely compact, presented in a minitower format. Inside, we located the controller with a Realtek RTD1296 quad-core CPU at 1.4 GHz speed, accompanied by 512 MB of DDR4 memory.

A fairly quiet 92mm active fan is responsible for cooling the internal components, while the front LED indicators inform us of the status of the unit. At a quick glance, we can see if the disks are active and if there is a LAN connection.

A physical button located next to them allows the system to be turned on or forced off. The 60 W power supply is external and the noise level operating in read mode remains below 20 dBA. We can program your on and off times.

Note here that it has two USB 3.0 ports to connect pen drives or similar, as well as a Gigabit Ethernet port to integrate it into a compatible network or simply connect it to the home modem / router and make it accessible to all family devices. 

Hard drives are attached to the drive with screws. To access its interior, the casing is easily removed from the front to allow the DS220J to be divided in two, making everything very accessible and easy to start up.

Its maximum gross capacity is 32 TB if you install a pair of 16 TB hard drives in its bays. Obviously, the final capacity may vary depending on the type of RAID you choose. 

If you choose according to Synology’s recommendation, with Hybrid RAID the volume management system is extremely simple, providing redundancy of a disk to protect data or backup copies in case of failure of either of the two units.


If Synology NAS is characterized by something, it is by its ease of configuration and startup. Physically connect the NAS to the Ethernet port of your router and connect with your computer pointing to the IP of the device.

If you have doubts, you can access online tools such as Synology Web Assistant with which they will help you find the address of your device to access it. With a graphical interface, follow the step-by-step configuration wizard and in just over half an hour you will have the NAS ready.

From this moment on, it is the moment to create a folder structure in which you will store content or backup copies of your computers and devices. The installation of services is simple, in the same way that you do it in any current smartphone

Aided by tools such as CrystalDiskMark , they allowed us to verify that the writing speed offered by the system with these Seagate IronWolf disks can reach 87 MBps on a sustained basis, while with read speeds it can reach 90 MBps. 

We do not have references of NAS systems previously analyzed, but we can mention that compared to the previous Synology DS218J system, the speeds seem to have improved by slightly more than 30%. 

You can consult our article on the best storage NAS systems in which competitor systems such as QNAP, Terramaster, WD and the odd model of the brand analyzed here appear. 

Broad ecosystem with DiskStation Manager (DSM)

If you have a complete library of music, photos and video content, the DS Audio, DS Photo and DS Video applications will give you access from any computer, tablet or smartphone to consult everything stored.

The Package Center of the current version of DSM has grown in recent years to the point that you can find more than 100 different applications among those provided by Synology and external developers. With IFTTT support you can automate tasks.

From antivirus solutions, backup and restoration, and media servers, to office applications. Click on the File Station tile to search for files, share them on various platforms, modify file structures or edit access privileges.

Price and configurations

The recommended retail price of the DS220J is € 216.74 in PC Components , slightly cheaper at Amazon , a price to which you will have to add that of a pair of 3.5 mm hard drives if you want to take advantage of the RAID configuration of the NAS. 

In our configuration and to carry out the tests, we have used two Seagate IronWolf disks of 2 TB each and 7200 rpm, whose price per unit amounts to € 83.11, with which we can have a complete solution for € 383 with the DSM included as standard. 

Users who anticipate a rapid growth of their data or business, can opt for the next higher model DS420J which has 5 3.5-inch disk bays to be able to scale the configuration to a much higher storage. 

Final verdict

The DS220J is an excellent option for those home users who want to create a personal cloud on their local network, connecting the device directly to a free Gigabit Ethernet port on their router. It is set up quickly and simply, without advanced knowledge. 

With the mode Hybrid RAID (SHR) is possible to have backups and backup your most important files with the certainty that if one of the two drives fails, still have access to all information. Additionally, there is the option of the cloud. 

The services that you can deploy on your NAS are infinite, from the most oriented to entertainment such as turning it into a media hub to transmit content to your Smart TV, or as a mail / web and application server. 

What the Synology J-series offers is guaranteed with the DS220J for performance and access to countless applications. If you foresee that your business could grow very quickly, opt for a 4-bay drive solution like the DS420J .
