Synology’s Latest DS1520+ 5-bay NAS Server of 2020 is a Familiar Beast

Share what you're reading!

Synology today announced the availability of its latest 2020 5-bay NAS server, the DiskStation DS1520+.

Per the NAS maker’s naming convention, this is a new high-end server for homes and SMBs that can house up to 15 drives. Five on its own and another ten via two expansion units.

In all, with each hard drive being available in up to 16 TB, the server can deliver up to 240 TB of raw storage space.

According to Synology, the new DS1520+ sports up to 8 GB of DDR4 RAM and an Intel Celeron Processor J4125. This quad-core CPU has a clock speed of 2.0 GHz and can burst up to 2.7 GHz.

As a result, the new server can deliver performance up to 126% in website responsiveness and a 19.8% increase in general tasks, compared to the previous model, in stock configuration.

But there’s more. Like other 2020 servers, the DS1520+ also comes with two M.2 2280 NVMe SSD cache slots on its underside. This enables NAS enthusiasts to add two fast SSDs, such as the Seagate IronWolf 510, as a cache that will boost the server’s performance significantly further.

Other than that, the new server includes four Gigabit network ports and two USB USB 3.0 ports. It’s a bit disappointing that it still has no multi-gig ports. You can, however, combine any pair of its ports to form an aggregated 2 Gbps connection.

The DS1520+ comes with four Gigabit network ports and two eSATA ports for storage expansion.

Running on an Intel chip, the new server is excellent for media streaming. Considering its power, though, it’s also a unique solution for those with various network storage needs. Examples of these include data backup of all types, virtual machines, and security surveillance. The new server can host up to 40 IP cameras.

That said, while most homes will find the previously released DS220+ adequate, savvy, and hardcore, users will find this new five-bay NAS a dream server.

And they won’t need to wait. The Synology DiskStation DS1520+ is available now at the suggested price of $699.99 (disk-less).

If you’re wondering how it will pan out, I’d recommend my take on the DS1019+ which is very similar without the support for a second expansion unit and two fewer network ports. Below is that server’s rating.
