Synology’s 2020 Plus NAS Gets NVMe Caching and Speed Boost

Synology DS220 NAS Server 10
Dong Ngo | Dong Knows Tech The Synology DS220+ NAS server.

If you’re in the market for a robust network-attached storage (NAS) server, there are now a couple of new and exciting options. Synology announced today its latest 2020 lineup of the Plus series that includes four brand-news servers, the DS220+, DS420+, DS720+, and DS920+.

More processing power and built-in NVMe caching option

All these servers sport faster processors compared with those of the previous 2018 release. Most importantly, other than the DS220+, the rest of the servers comes included with two M.2 NVMe slots for optional caching, using SSDs like the Seagate IronWolf 510.

Built-in NVMe slot a new trend that started with the DS1019+ that came out last year. Prior to this, in some older servers, you have to use an add-on adapter.

All of the new NAS servers run Synology’s latest DiskStation Manager operating system (DSM), currently in its 6th revision. They all will also support the upcoming DSM 7.0.

Faster and more secure storage experience

According to Synology, highlights of the new Plus servers include:

Turbocharged experience – Up to 133% faster in website responsiveness and over 15% improvement in compute-tasks, the new Plus series enables you to get things done faster and more efficiently. Select models come included with two M.2 NVMe slots that enable accelerated I/O performance, especially in multi-user environments. 

Subscription-free Surveillance Hub – Surveillance Station is a powerful surveillance software that runs on Synology NAS. It is a web-based solution, so users can monitor and manage cameras on any computer. Surveillance Station also allows admins to archive and consult past recordings, manage user permissions, or even interface with analog devices, such as door controllers.

Data protection for everything – With Active Backup suite, Synology NAS can not only fulfill data management requirements, but also centralize backups for Microsoft Windows PCs and Servers, VMware vSphere Microsoft Hyper-V VMs, and Microsoft 365 and G Suite accounts.

Build your own private cloud – Access your data without boundaries with the level of privacy you deserve. Granular access rights, customizable passwords, and expiration policies for file sharing put you in control of your data. Easily synchronize with remote sites for distributed work, and set up data encryption for your most sensitive files.


The new DS220+, DS720+, DS420+, and DS920+ are available for purchase now with the disk-less suggested price of $299.99, $399.99, $499.99, and $549.99, respectively. You can get an idea of what they have to offer via the full review of the DS220+.

  1. Hi Dong —

    Still not quite clear of the utility of NVMe in a NAS. My understanding is that it will speed up performance of the NAS — typical SSDs (or HDDs) for storage, and adding the NVMe will then speed up file access, etc.? I’m a film director who is looking for a home setup, I move a lot of video around. Am thinking a 4 bay Synology based on your recs, deciding whether the NVMe capability is worthwhile for me. Much thanks for any comment.

    • Hi Robert. For your situation, I’d recommend using SSDs as storage (in this case cache is not necessary.) Also, you might want tot to think about getting a 10 Gbps network card for it.
      So I’d recommend what I’m using:

      1. The DS1618+
      2. WD Red SA500 NAS SSD, the 2.5-inch version, not M.2.
      3. This 10 Gbps add-on card. Or this one.
      4. A 10 Gbps router or switch. Like the RT-AX89X.

      Caching will make things faster but not fast enough for your need. I might write a post that explains the difference between the two at a later time.

      • Hi Dong —

        Much thanks for the quick reply. I’d wondered if network speed might be a bottleneck. I’ll be taking your advice and will definitely order through this site. And I for one would be interested in a post that explains the differences and use cases of the two.

        Thanks again,


  2. Greetings, I am considering either the DS220+ or the DS720+ as an upgrade from my DS215j. I am happy with 2 bays so the eSata is not a big deal for me, so my question is how much more performance does the quad core processor (& potential ssd cache) of the DS720+ offer over the DS220+? Worth the extra $100?

    • Coming from a J model, Charlie, you’ll be VERY happy with the DS220+ as is. But the DS720+ with SSD cache will be significantly faster than the DS220+. Differences in CPUs are minimal.

  3. Hi Dong, great review as always. I’m currently using a DS213J and feel like it’s due for an upgrade, despite no issues to date. The 220+ is about 35% more expensive than the 218+ for me. Do you think it’s worth it to get the 220+ or save some cash and get the 218+? My use cases are mainly for windows backup, cloudstation, and streaming files through DLNP (no transcoding needed), though it’s probably more due to the lack of power in the DS213j…
    Also do you have any guides on the best way to migrate files from old NAS to new? I believe I can’t just pull the old HDD from the j model into a + model, according to the synology migration table.

    • No, get the DS218+, Michael. In your case, you will virtually see no difference between the two.

      You can move the drives, however, you shouldn’t. That’s because you want to use the btrfs file system on the + model and set it up with new disks is the only way. That said, get the DS218+ with new drives, set it up from scratch with just one user account, copy the data over from the DS213j using the same names for Share Folders, then make a backup of users, apps, and settings on the DS213J and restore those on the DS218+. In that order.

      Have fun!
