Our selection of the top Synology NAS you can buy in 2023

Synology DiskStation DS1522+

Best overall

Perfect for both work and play

With the mid-tier Synology DS1522+, you get the best of Synology’s latest NAS lineup, including a super-fast AMD processor, the option to bump the RAM to a whopping 32GB, and an optional 10GbE network port. It can easily meet both your office and home needs without burning a hole in your pocket.

Pros

• Solid performance bump over the DS1520+
• Upgradable RAM and network port
• Ample drive bays that you can expand further

Cons

• No video transcoding on the fly
• Proprietary network adapter for 10GbE upgrade

The DiskStation DS1522+ tries to bridge the gap between the outgoing DS920+ and the uber-expensive DS1621+. You get four 1GbE LAN ports, enabling link aggregation or wired connection with a bunch of computers in your office. The best part is that the NAS comes with a (proprietary) slot where you can add a 10GbE network port as a separate purchase, keeping the cost low for those who don’t need a faster port — while still giving power users an upgrade option.

Compared to its direct predecessor, the DS1522+ gets a bump to a more powerful dual-core AMD processor, which is made for taxing business environments. And with 8GB of standard RAM (upgradable to a whopping 32GB), you can run virtual machines and server apps all you want. But without a GPU, don’t expect it to transcode your videos on the fly, although streaming already transcoded media shouldn’t be an issue.

Synology DiskStation DS1621+

Premium pick

It doesn’t get any better than this

One of the beefiest desktop NAS you can buy from Synology, the DS1621+ is the way to go for all your heavy work needs, be it multi-cam surveillance or running virtual machines. That quad-core AMD processor can handle it all without breaking a sweat.

Pros

• Super-fast and reliable AMD Ryzen processor
• Easy upgrades with PCIe accessories
• Scalable with two expansion units

Cons

• Only 4GB of standard RAM
• Included LAN port is 1GbE

If the DS1522+ doesn’t cut it for you, you can go for the Synology DiskStation DS1621+, which is beefier in nearly all areas. Starting with the available storage space, the DS1621+ lets you add six hard drives before you need to buy an expansion unit to store more data. This is a big deal for small businesses with massive data needs, giving them some extra headroom to work with in the long run.

Speaking of businesses, the DS1621+ is designed for workplace users instead of home users, which is why an AMD processor makes more sense on this NAS enclosure. The quad-core Ryzen chip offers a far superior raw performance over the Intel Celeron range usually found on retail NAS boxes. It’s very well suited for heavy lifting, from running virtual machines and server-class apps to supporting tens of users accessing the files simultaneously.

With the DS1621+, you get a PCIe slot to add a bunch of compatible accessories to the NAS, including a 10GbE LAN port. However, the base model of this NAS enclosure starts with only 4GB of RAM, so you will have to increase the RAM from the get-go. Alternatively, you can go for the upgraded DS1621xs+ model, which gets you an even beefier Intel Xeon processor, a built-in 10GbE port, and 8GB of base RAM.

Synology DiskStation DS224+

Best value

The perfect NAS for home users

The upgraded DiskStation DS224+ now comes with a quad-core processor borrowed from one of Synology’s most popular consumer enclosures. The performance upgrade allows it to be an even more capable desktop NAS device for home users who want to stream 4K movies and also get a bit of work done.

Pros

• Quad-core Intel CPU
• Excellent software
• Affordable price

Cons

• Not too different from the DS220+

The Synology DiskStation DS224+ looks very similar to the outgoing DS220+, but that doesn’t mean there is nothing new on the inside. The new model comes with a crucial upgrade in the form of its processor. The DS224+ uses a quad-core Intel Celeron processor that Synology previously used on its DS920+ — perhaps Synology’s most sought-after NAS model of all time. While this processor may not be the newest one around, it brings some notable improvements to this budget NAS over its predecessor.

We had no issues transcoding and streaming 4K videos on the DS224+ with Plex, which isn’t surprising since the DS920+ was often hailed for its media capabilities. In fact, we were able to run multiple streams of 4K videos simultaneously, and the DS224+ didn’t break a sweat. Our testing also confirmed that the transfer speeds can hit 210MB/s easily, which is more than enough for most home users and even some office tasks.

Its 2GB of standard RAM could be an issue if you do a lot of multitasking, but most users should be able to get away with the base package without having to worry about the RAM. However, if you need it, you have the option to expand the RAM to 6GB by slotting in a 4GB stick.

Synology DiskStation DS423+

Made for Plex streaming

For your streaming needs and more

Synology’s new DS423+ has an uncanny resemblance to the popular (but now discontinued) DS920+ from the inside out. This means you’re getting the same excellent package for a lower price now. And the best part is that the DS423+ uses an Intel Celeron processor with an integrated GPU for perfect Plex streaming.

Pros

• Integrated GPU for video transcoding
• Takes two NVMe drives for caching
• Ample storage space

Cons

• No support for Synology expansion unit
• Only 2GB of base RAM

While Synology has been switching to AMD processors for many of its NAS models, it stuck with the good-old Intel Celeron J4125 processor on the DiskStation DS423+ — the same quad-core one used on the DS920+. The processor may not be the newest variant around, but it’s still a pretty capable chip for a consumer NAS. Its four cores can easily handle multiple apps and tens of surveillance cameras simultaneously. And if you’re wondering, the DS423+ is a perfect fit for Plex streaming as its integrated GPU can do the heavy lifting when transcoding media files on the fly.

Like its predecessor (the DS420+), the DS423+ is also a four-bay system, allowing you to insert four drives of 16TB each for a total capacity of 64TB (without accounting for redundancy). That’s more than enough for household use involving photo backups, media streaming, surveillance, and more. However, the 2GB of base memory is expandable up to only 6GB. And since the DS423+ isn’t designed for commercial use, it lacks an eSATA port that lets you attach a Synology expansion unit to add more drives.

Synology DiskStation DS723+

Compact powerhouse

Get all the power in a compact body

The Synology DS723+ comes with the internals of its more expensive siblings but without a bulky build. So, you can easily keep it on your desk and hook it directly to your computer with a LAN cable. Easy peasy.

Pros

• Snappy performance with Ryzen processor
• Compact, two-bay system for home office use
• Supports expansion unit

Cons

• Only 2GB of standard RAM
• No integrated GPU for video transcoding

For individual professionals and freelancers working from home, a NAS enclosure’s horsepower tends to be more crucial than its storage capacity. If you fall in that category, the new DS723+ is the right Synology NAS for you. This new model gets you the brains of the pricier DS1522+ but with a compact design of the DS220+ — all at an affordable price. In addition, the two-bay DS723+ comes powered by the dual-core Ryzen 1600, making it one of the best-performing NAS units in its price bracket.

However, the switch to a Ryzen chip may not go down well with those looking to run a Plex server on their DS723+. Due to no integrated GPU, you must ensure that your media files are in a format your client devices support so that the CPU isn’t overburdened with media transcoding while streaming content.

Synology has included eSATA and PCIe slots for attaching accessories or Synology’s expansion unit for a total of seven drive bays. You can further boost the NAS’s performance by adding two NVMe drives dedicated to caching, but its 2GB of RAM remains a sore point. You can expand the RAM up to 32GB, but you’ll have to spend extra on it.

Synology DiskStation DS923+

The new default

The mid-tier champ for home offices

Replacing the uber-popular DS920+, the Synology DS923+ comes with a familiar and compact design and a more powerful processor to easily handle all your office needs. It is a great fit for your home office as it gets you the best of the DS1522+ but at a slightly lower price.

Pros

• NVMe drives can be used as storage
• Excellent performance with the AMD chip
• Supports up to 32GB of RAM

Cons

• Lacks integrated GPU
• Included network ports are still 1GbE

The DiskStation DS923+ is the follow-up to arguably the most popular NAS model in Synology’s lineup: the DS920+. With some notable changes on the inside, Synology has put this new mid-tier model right up against its premium options. The DS923+ comes with the same Ryzen R1600 processor as many of its pricier siblings. While the AMD chip is indeed more powerful, it now lets you add up to 32GB of RAM as well, making the DS923+ a perfect NAS for small businesses and home offices.

Much like the DS1522+, you can use the included PCIe slot on the DS923+ to add a 10GbE network card to make full use of the NAS’s capabilities. With the right setup, the company claims the NAS can read and write data at over 500MB/s. A big change that Synology introduced with the DS923+ is that you can now use your NVMe drives as storage instead of just caching, which can help speed up your data transfers significantly. These changes alone make it a worthy upgrade over the outgoing DS920+.

The choices that Synology made with the DS923+ have some downsides, too. For starters, the NAS lacks an integrated GPU, which isn’t ideal if you’re looking for the best NAS for running a Plex server. And though the two included LAN ports support link aggregation, it’s a shame that they are still 1GbE each.

Synology DiskStation DS223j

Two-bay NAS for less

Excellent budget starter pack

The DiskStation DS223j is a two-bay budget NAS that gets you ample storage space for all your home and office files without many fancy (and expensive) features. Synology has given it a new Realtek processor for better performance than its predecessor. It’s a bargain compared to the amount of cash it will help you save in the long run over a cloud storage subscription.

Pros

• Two-bay NAS for cheap
• Made for data backup and storage
• Access to Synology?s excellent software

Cons

• Not the most powerful NAS around

Unlike the Plus-branded Synology NAS models, the J series isn’t meant for heavy tasks like media transcoding. For regular file storage and sharing at your office, the DiskStation DS223j will do a perfect job. It is also an inexpensive way of maintaining an offsite backup of your main server to enhance the safety of your data. And its two HDD bays can hold tens of TBs of data, which is enough for homes and most freelancers.

While you can get similar budget NAS enclosures from other brands for less, not many can match the polish Synology’s operating system comes with. You get the latest and refreshed DSM 7 out of the box, and the accompanying first-party apps work like a charm. The CPU and RAM combination the DS223j comes with is well suited to run DSM without any issue, but don’t expect a lot from this hardware.

The DS223j sure has a few downsides, like it still uses a 1GbE network port and there is no expansion slot, but these choices have helped make the NAS affordable. You can put together a whole package with a pair of hard drives for under $300, which is quite reasonable for home users on a budget.

Synology DiskStation DS120j

Budget champ

All the smarts in an entry-level package

The Synology DS120j can be the right replacement for your good-old USB hard drives to back up your family photos seamlessly. Once you set it up, the NAS will automatically take care of your photos over Wi-Fi without you having to take a backup manually every few days. And the DS120j doesn’t even cost a lot to get started.

Pros

• Excellent value for budget shoppers
• Comes with the latest DSM 7 OS
• Compact and power-efficient

Cons

• Single drive means no data redundancy
• High-res video streaming may not be the smoothest

Getting your first NAS enclosure shouldn’t mean spending several hundred dollars upfront. You can pair a single-drive DiskStation DS120j with a 4TB HDD (supports up to 14TB) for under $200. And for that price, you get the same excellent Synology software as the more premium NAS units. The DS120j is perfect as a Google Photos alternative to store your family photos and videos, or you can use it as a secondary backup system for your primary NAS.

The DS120j is a power-efficient, compact machine you can easily tuck away on a shelf. Even on your desk, it won’t take up a lot of space. Its processor and RAM configurations are enough for data storage and light streaming needs but don’t expect it to play 1080p or higher-res videos without a hiccup. Just make sure to pick up a 7200 RPM drive to make the most of the NAS’s transfer speeds, and you will have an unbeatable package for its price.

Which Synology NAS is best for home use?

Most home users will be happy with the all-new Synology DiskStation DS224+, which happens to be an upgraded model of our previous favorite NAS enclosure for those on a budget. Its new internals make it a powerful machine that is capable of doing a lot more than its predecessor. It is perfect for streaming 4K movies on multiple devices, and handling transcoding on the fly is a breeze for its new chip. If you decide to bump up its RAM to 6GB, you can even use it for your freelance work from home, which can involve a bit of multitasking on the NAS.

Synology’s new DS423+ could be even better for home use if you plan on streaming a lot of movies from Plex that need transcoding on the fly. It comes with the same quad-core processor as the now-discontinued DS920+, so performance won’t be an issue for years to come. If you have the budget for it, the DS423+ is great for all your home needs, and with its RAM expanded to 6GB, you could even get some work done on it.

In case all this sounds overkill for your basic home use that involves nothing more than saving your family photos and videos in a safe place, backing up your computers, and safekeeping your old files that you’re too lazy to get rid of, you can easily get away with the new DS223j. It is a super cheap dual-bay NAS that gets you plenty of storage space without going for a costlier model if you don’t need the extra horsepower. And if you’re on an even tighter budget, the entry-level single-bay DS120j should do the job without burning a hole in your pocket.

The perfect middle ground for mixed-use

As your usage grows, like in the hybrid work environment of today, the demand for raw hardware performance will also increase. That’s where our upgraded picks — the DS1522+ and the DS923+ — come in. With both these models, you get a much more powerful processor and ample RAM to take care of all your advanced work applications. Handling multiple streams of security cameras or supporting a small team is a breeze for either Synology enclosure. You can even set up Synology Drive as your native Google Drive alternative for your entire team, which is one of the best parts of owning a Synology NAS.

Where the DS1522+ scores more than the DS923+ is its additional drive bay, 8GB of base memory, four LAN ports, and two eSATA ports for adding two drive expansion units. And you get all those extra benefits by spending just $100 more over the DS923+. But if you don’t care about all those extras, which could be the case if you are a freelancer or work from a home office, you can easily get by with the DS923+, considering how similar both models are otherwise, while saving some cash, which you can invest in NAS-specific hard drives.

The DS1522+ and the DS923+ use the same AMD processor that lacks an integrated GPU, making both of them a little less ideal for transcoding videos as it would stress out the CPU pretty quickly, depending on the file size and type. But if your media is already transcoded in a format that your client devices (such as your TV set) already support, then using either model or even the two-bay DS723+ won’t be a problem.

Synology NAS for the pros

There is a subset of users that doesn’t fall under any category discussed above and needs a powerful server for their large team or run more resource-intensive apps like a virtual machine, be it Windows or any Linux distro. And for something like that, a Celeron or a dual-core AMD chip doesn’t cut it.

What your business needs is the Synology DiskStation DS1621+ — the most powerful desktop NAS enclosure on this list. Its highlights are the uber-capable quad-core AMD processor and the ability to rock a whopping 32GB of RAM, making it suitable for advanced workloads. You can easily run Windows applications and maybe even play a game or two with RetroArch when not working. Plus, you will appreciate having ample performance headroom in the long run when your team size grows, or your NAS’s workload increases.

Synology also makes even bigger and beefier systems, like the DiskStation DS36xx series, which comes with a class-leading Intel Xeon processor and up to 12 bays for storing and efficiently processing hundreds of TBs of data. But you must also be prepared to pay a premium price for such top-of-the-line models, which can run into thousands of dollars for the complete package.

Prepare for the future in any case

While adding more hard drives in available slots or using expansion units is easy, upgrading your Synology NAS’s performance capability won’t be easy — or cheap. Getting a NAS is a long-term investment, so it’s better to stretch your budget slightly to get an upper-tier enclosure from the get-go, especially if you’re buying one for your work needs.

And while you’re budgeting, don’t forget to account for the NAS-specific hard drives that can significantly drive up your initial cost. You can save a bit on that investment by starting with a couple of HDDs and adding more as your needs and team size grow.

Synology DiskStation DS1522+

Best overall

Perfect for both work and play

With the mid-tier Synology DS1522+, you get the best of Synology’s latest NAS lineup, including a super-fast AMD processor, the option to bump the RAM to a whopping 32GB, and an optional 10GbE network port. It can easily meet both your office and home needs without burning a hole in your pocket.
