The best Synology NAS in 2022

With all the upgraded internals the DS920+ brings to the table over its cheaper siblings, it becomes a sweet spot for prosumers who want to do more but without breaking the bank. The more powerful Celeron CPU and 4GB of default RAM give the NAS the extra horsepower to run more demanding apps and tasks like multi-camera surveillance and team collaboration. While the four-drive system should be enough for most users and home offices, the DS920+ lets you add an expansion unit if your storage needs increase later on, making it a future-proof investment.

The DiskStation DS220+ is the perfect package for anyone looking to get their first NAS. It balances its performance and value proposition pretty well — a crucial factor for something catering to home users. Its two bays let you add up to 32TB of total storage, which is ample for personal use even after accounting for redundancy. The best part is that the DS220+ uses an Intel Celeron processor paired with 2GB of RAM, making it more than capable for 4K streaming through Plex and similarly demanding use cases.

If two drive bays seem limiting and you’d like to have more of them at your disposal, the DS420+ should fit your bill. With four HDD bays, you can have a storage pool of up to 64TB — double of what you get on the DS220+. It should be suitable for giving you extra headroom for years to come and the flexibility to add more drives in the future if you want to start with just a pair. The DS420+ also allows you to make use of RAID 5, 6, and 10 for improved data integration and even speed up data transfers with the option to add two NVMe sticks for caching.

For those looking to upgrade their existing Synology NAS or want a new system for their small businesses, the beastly DS1621+ is a solid option. One of the biggest improvements it brings to the table is with its Ryzen processor. The AMD chip is not only is a nice change of pace from Intel’s domination but is also capable of doing the heavy lifting, like running server-class applications and virtual machines. In addition to the standard set of ports, you get a PCIe slot, which opens up the possibility of hooking a bunch of accessories, including the option to add a 10Gbe LAN port. While the RAM used here is of ECC variety (that helps with data integrity), it still starts at a meager 4GB, with a 16GB model also available. Synology also offers an upgraded model named DS1621xs+ that packs an even better Intel Xeon processor, a built-in 10Gbe port and starts at 8GB of RAM.

The DiskStation DS720+ sort of sits in the middle, offering similar internals as the DS920+ but with only two drive bays. It is a thoughtful middle ground if you don’t want something bulky sitting on your desk or need a lot of storage space. You still get the eSATA port for attaching an expansion unit in case you ever want to add more HDDs to your NAS. One downside of the smaller DS720+ is that you have to make do with just 2GB of RAM out of the box or upgrade it post-purchase.

The DS220j cannot match the DS220+ in terms of raw performance and isn’t particularly ideal for things like running multiple streams of videos. But its biggest selling point is its price. For less than $200, you get a Synology NAS that runs the same DSM 7.0 version and quality first-party apps as its much beefier siblings. Its basic hardware makes it a good deal if you’re looking to use it only as a storage unit for all your data or as an off-site backup option.
