Closer Look at the Synology DS 1819+
Just like most of the NAS devices by Synology, the DS 1819+ is an ABS plastic shell with a rolled steel chassis and the backplate. The dimensions of this NAS are 166mm x 343mm x 243mm with a weight of about 6Kg or 12Lb without drives. Most of the weight comes from the steel skeleton and enclosed 250W power supply. Eight drive bays are accessible from the front of the unit. Users have the ability to lock the trays for either security reasons or to keep the drives intact while in transport. Note there is a USB 3.0 connector in the front of the enclosure.
There are two cut out Synology logos on both of the sides of the NAS. These cutouts are covers from the inside by a filtered mesh. The entire enclosure sits on four plastic/rubber feet.
There aren’t many buttons here. In fact, there is the only one which is located in the front of the unit. You can also find six LEDs in the front that provide basic status and alarm levels of the device.
On the back of the Synology DS 1819+ there are two SATA2 external connectors, a four 1 gigabit RG45 ports, reset pinhole, three USB 3.0 connectors, and a PCIe slot for any addon cards. The DS 1819+ supports multiple external cards including 10GbE cards. Check Synology’s website for a list of supported cards.
Our unit came with 4 Gb of RAM (4Gbx1) however, this module can be pulled out and replaced with two 16Gb modules and has a maximum capacity of 32Gb. Right next to the RAM door there is a small service hole with few jumpers. I could not find any information on this so I am guessing this is a Synology service port to be used by Synology technicians.
Once the front trays removed you are able to see the SATA backplane of the NAS.
The entire enclosure is being powered by an internal power supply which has a Max Power of 250W and is 80Plus (Bronze) efficiency.
DS 1819+ is actively cooled by two rear-facing 120mm fans. These fans are not PWM enabled however, they do have a low rotational speed. Some custom profiles that can be set from within the OS are Full-Speed Mode, Cool Mode, and Quiet Mode.
The add-on cards for the DS 1819+ could be bought online but only a few are supported by Synology. We have a list of the supported models which would work in the PCIe slot.
| Model | Ports | Connector | Interface |
| E10G15-F1 | 1 x 10GbE | SFP+ | PCIe 2.0 x4 |
| E10G17-F2 | 2 x 10GbE | SFP+ | PCIe 3.0 x8 |
| E10G18-T1 | 1 x 10GbE | RJ45 | PCIe 3.0 x4 |
| E10G18-T2 | 2 x 10GbE | RJ45 | PCIe 3.0 x8 |
