2019-11-12 09_51_26-DS620slim _ Synology Inc.

The newly-released Synology DS620slim is a small yet powerful NAS device that’s considered a fresh new offering from the company, in terms of design. But one thing’s for sure; it is fundamentally superior to the DS419 slim that also came out just recently.

Today, we will focus on the DS620slim from Synology, especially if you’re someone who’s in search of an advanced NAS that has a stylish design, is compact, and is also silent when working even on heavy loads. But the thing is, is it as useful and efficient as what Synology claims it to be? We’re going to learn more about this NAS, its features, specifications, software, and how well it performs.

First up, let’s take a look at what’s inside the box.

Synology DS620Slim Review – What’s in the Box?

The Synology DS620slim comes in a simple and straightforward cardboard box that is durable enough to safeguard the NAS while in transit. The company made sure to keep things clean and uncomplicated, so they only included their name and the word “DISKSTATION” on the lower-left portion of the box. The upper-right part of the box displays a sticker that exhibits an image of the Synology DS620slim itself. It also includes the NAS’ essential features, and a few vital information such as the bay count, model information, and the hardware specifications.

Inside, you will get the Synology DS620slim kept protectively and securely in place, preventing it from acquiring damages while in transit. Aside from the NAS, other items included in the box are the quick installation guide, two Ethernet cables, and a power adapter.

The Synology DS620slim uses an Intel Celeron J-3355, which is a two-core processor that can be configured and arranged up to 2.5 GHz. It features up to a total of 6 GB of DDR3L RAM; plus, it also comes with an internal raw capacity of 30 TB, including a wide selection of supported RAID types. When it comes to its performance, the Synology DS620slim is said to deliver over 226 MB/s for reads & 198 MB/s for writes.

For convenience, a two-year warranty also supports the NAS device from Synology, which is something that they usually offer.

The Synology DS620slim makes use of the Intel Celeron J-3355 with a CPU architecture of 64-bits. Its CPU base frequency is a dual-core 2.0 with a burst frequency of 2.5 GHz; plus, it’s a NAS device that comes with a pre-installed 2 GB memory module and a system memory of 2 GB DDR3L.

It’s a convenient device with a total of two memory slots, plus six drive bays with a memory that can be expanded up to 6 GB (2 GB + 4 GB). 2.5-inch SATA HDDs and 2.5-inch SATA SSDs are compatible with this NAS from Synology. Also, it has a maximum internal raw capacity of 30 TB (5 TB drive x6). It can handle a maximum of 108 TB for its single volume size.

When we talk about its external ports, this hot-swappable device comes with 2x RJ-45 1 GbE LAN ports with failover support/link aggregation, as well as 2x USB 3.0 ports. For the internal drives, file systems include the Btrfs and EXT4, while external drives include Btrfs, EXT3, EXT4, FAT, HFS+, NTFS, and exFAT. However, keep in mind that the exFAT access can be purchased separately in the Synology Package center.

The important thing to remember when setting up a new NAS is to ensure that you use high quality hard drives in them. The Synology DS620slim is an amazing bit of hardware, however it won’t be able to protect you from hard drive failure. We highly recommend Seagate hard drives due to their reliability and performance when it comes to NAS solutions.
