Design and Hardware
Synology DS220+ is a rectangular boxed-shaped NAS device with a matt black textured finishing and four corner legs.
It has an engraved Synology logo on its right side.
Synology DS918+ is a boxed-shaped NAS device with a matt black textured finishing just like its opponent. It also has an engraved Synology logo on its right side (from the front view).
Both of them have status indicating LEDs, a power button, and a USB 3.0 port on their front panels.
The difference is that DS220+ has a USB Auto Copy button and DS918+ has 4 Drive Tray Locks in their front panels.
On their rear panels, they have a pair of LAN ports, a reset button, a power supply port, a USB 3.0 port, and one Kensington security slot.
DS220+ has only one exhaust fan on its rear panel while its competitor is equipped with two fans of the same also.
Also, DS918+ has an eSATA port for expansion purposes while its competitor doesn’t.
Having additional drive bays, an eSATA port for expansions, and an additional exhaust fan gives Synology DS918+ an edge over its competitor from the hardware point of view.
But DS220+has an Auto Copy USB button which gives it an extra feature over its competitor.
From a design perspective, DS220+ is a better-looking device with a compact design and shining bevel structure on the front panel.

Features of Synology DS928+
Despite having a relatively fast processing speed and efficient energy consumption, Synology DS918+ possesses all the above-mentioned features of DS220+.
But there are still other important features it provides which are mentioned below.
- It allows you to increase drive bays by combining them with extension devices.
- It has an M.2/NVMe 2280 SSD in it which enhances its cache creation process without subjugating the space of drive bays.
- Its DiskStation Manager (DSM), a web-based system, allows its users to manage and store their account information efficiently.
- Its Collaboration Suit opens up the door to business collaboration in an effective manner.
- The device also allows real-time transcoding of two 4K HD videos at the same time.
DS918+ has some additional and advanced features which give it superiority over its competitor in this regard.
Processing Speeds:
Since the clock speed or CPU frequency of DS220+ is relatively higher than its competitor, then its data interpretation and processing speed would also be higher.
Reading/Writing Speeds:
The reading speed of Synology DS220+ and DS918+ is 225 Mbps and 226 Mbps respectively.
And the writing speed of Synology DS220+ and DS918+ is 192 Mbps and 222 Mbps.
As we can see both the writing and reading speed of DS918+ is relatively higher than its competitor.
Data Storage Capacity of both devices:
Data storage of any NAS storage device depends on the number of drive bays it possesses and how many extended bays can be added to it.
Synology DS220+ has only 2 drive bays and it can’t be extended furthermore.
Since Synology DS918+ has 2 extra drive bays and can be extended up to a total of 9 drive bays, it is sure to save more data compared to its opponents.
Differences in Warranty
Even though both products are being made by the same manufacturer, their warranty period is different.
Synology offers 2 years and 3 years of warranty for DS220+ and DS918+ respectively.
Both products are being regulated by part 15 of the Federal Communication Commission.
