Structure and Design
Synology DS218J is a white-coloured vertically designed cloud device. Its front is equipped with LAN, status and drive lights aligned vertically on the extreme left edge.
Near the bottom left corner, there is a power button and indicator.
The upper half of its rear is occupied by the system fan and below it a USB 3.0 port is present.
Moreover, a reset button, an RJ-45 LAN port, a power button and a Kensington security slot also inhabit its back panel.
Synology DS218play is entirely identical to its counterpart in its external design and structure even though its weight and dimensions are also equal to that of its opponent.
The only difference is in colour. This device is coloured black with a polished and sleek outlook.
Its front panel is equipped with the same LED indicators and power button on the same positions.
Moreover, its system fan is of the same size as that of its peer.
|Structure & Design||DS218J||DS218play|
|Dimensions (L x W x H)||8.88” x 6.5”x 3.94”||8.88” x 6.5” x 3.94”|
|Weight (lbs)||1.92 lbs||1.92 lbs|
|System Fans||1 x 92 mm||1 x 92 mm|
However, both devices are identical twins in their structure but the polished black exterior of DS218play grants it a more attractive appearance.
Compare them with other devices:
- Synology DS216j vs DS218j
- Synology DS218j vs WD My Cloud EX2 Ultra
- Synology DS220+ vs DS218play
- Synology DS218 play vs DS220J.
Synology DS218J is powered by a 1.3 GHz dual-core processor which allows it to deliver 113 Mbps of reading and 112 Mbps of writing sequential throughputs under RAID 1.
However, its encrypted data throughput is limited to 105 Mbps of reading and 58 Mbps of writing.
Whereas, Synology DS218play being powered by a 1.4 GHZ quad-core processor delivers 112 Mbps of reading and 112 Mbps of writing sequential throughputs under RAID 1.
Its encrypted sequential throughput is also up to 112 Mbps for both reading and writing.
|Throughput Under RAID 1||DS218J||DS218play|
|Encrypted Data Throughput||–||–|
However, DS218J delivers a slightly higher writing throughput under RAID 1 but DS218play is far better than the former in encrypted sequential reading and writing speeds.
Supported OS and Browsers
DS218J supports the following OS:
- Windows 7
- Windows 10
- Mac OS 10.11 or later
Whereas, the OS compatible with DS218play are:
- Windows 7
- Windows 8.1
- Windows 10
- Mac OS 10.11 or later
Both support the same browsers.
Hence, both devices support the same browsers but Synology DS218play also support Windows 8.1, which is not compatible with its competitor.
Synology DS218J offers a slightly narrower range of operating temperature but its storage temperature and operating humidity ranges are equal to that of its foe.
Synology DS218play has the same operating altitude as offered by its rival but it is comparatively noisier.
It may be due to its higher-speed quad-core processor which is more likely to heat up and the system fan rotates at greater speed to cool it down, resulting in more noise production.
|Operating Temperature||5°– 40°C||4°– 40°C|
|Storage Temperature||-21°– 60°C||Same|
|Operating Humidity||5% – 95%||Same|
|Noise Level (dBA)||18.2||19.9|
Hence, Synology DS218J produces lesser noise, so it is comparatively environment-friendly.
Being powered by an AC adapter, DS218J demands 100 to 240V of AC input power.
Its power frequency is from 50 to 60 HZ.
However, it consumes comparatively more electricity in typical and rest conditions.
DS218play is also powered by AC adapter. Its AC input power and frequency range is the same as that of its peer.
It demands 60V of DC input power but consumes comparatively less energy in working and rest states.
|Power Source||AC Adapter||Same|
|AC Input Power||100 – 240V AC||Same|
|Power Frequency||50/60 HZ||Same|
|Power Consumption||17.48W (Typical) 7.03W (Rest)||16.79W (Typical) 5.16W (Rest)|
DS218play, consuming comparatively lesser power is more friendly towards electrical conditions.
When it comes to price, DS218J is comparatively economical.
Being cost-friendly it is usually preferred by most users.
DS218play is not noticeably expensive as compared to its counterpart.
