What's in the box?:
The DiskStation DS620slim comes in a small, brown box. Along with a picture of the unit, the sticker on the front advertises many of its key features including its 6-bays, dual-core processor, expandable RAM, data protection by Btrfs and 4K H.264/H.265 transcoding. The back of the box provides a bit more information regarding the DS620slim's physical features as well as the package contents.
Inside the box you'll find the DS620slim as well as an AC power cord and adapter, two ethernet cables, quick installation guide, a bag of screws and a couple of keys for the drive bays.
The look of the DS620slim is very similar to Synology's other desktop NAS servers. Designed for home and small business environments, the device is constructed out of black plastic and measures 121 x 151 x 175 mm. The DS620slim also tips the scales at 1.4 kg without any hard drives installed.
Along with its six, 2.5" drive bays, the front of the DS620slim has a series of LED indicators. These LED's are used to show the current state of the hard drives, network, and if there are any alerts regarding the fan or the temperature. The brightness of these LEDs can be adjusted or turned off altogether through the control panel within DiskStation Manager (DSM).
The rear of the DS620slim is pretty straight forward. To keep the hard drives cool, the NAS is equipped with a single 80mm fan. While the fan doesn't appear to be temperature controlled, you can control its speed from within DiskStation Manager. Below the fan, you can see the DS620slim's power connector, two gigabit ethernet ports and a pair of USB 3.0 ports. These USB ports can be used to connect external storage devices, printers and other devices to the NAS.
Upgrading the memory on the DS620slim is pretty straightforward. To access the RAM slots, you'll need to remove a handful of screws and then pop off the bottom panel.
