Synology DiskStation DS224+ vs. DS723+: Which NAS is best?

Buying your very first NAS enclosure can prove challenging, especially if you’re unsure how to navigate and decipher all the jargon. Do you go with ECC memory, how about AMD over Intel or even integrated graphics? These are all questions we’ll be asking when comparing the Synology DiskStation DS224+ vs. DS723+.

  • More affordable
  • Same excellent OS
  • Lower power draw
  • Weaker CPU
  • No M.2 slots
  • No expansion support
  • No PCI slot
  • Non-ECC memory only

The Synology DiskStation DS224+ was launched to replace the old DS220+. Synology didn’t change too much inside the enclosure but did upgrade the CPU to provide better performance across the board.

  • More powerful CPU
  • Same excellent OS
  • M.2 SSD slots
  • PCI slot for optional LAN upgrade
  • Expansion support
  • No integrated GPU
  • More expensive
  • Higher power draw

Synology’s DiskStation DS723+ may be slightly older than the DS224+ but it has a better AMD Ryzen processor, higher RAM support (with ECC), expansion support, M.2 slots, and more. So long as you don’t mind paying more.

The Synology DiskStation DS723+ is the better NAS in almost every way when compared to the Synology DiskStation DS224+. That’s because the former is designed with enterprise and enthusiast use in mind. The DS224+ is for those who are new to NAS or need local file storage for the home. The DS224+ is cheaper, which may win those over who have tighter budgets.


In terms of specifications, the Synology DiskStation DS224+ vs. DS723+ comparison couldn’t be more interesting. The DS723+ is almost better in every way compared to the newer DS224+, though this is to be expected as both enclosures are designed for different demographics.

The Synology DiskStation DS224+ is an Intel-powered NAS with the same Intel Celeron J4125 chip found in previous-gen DS720+ and DS920+ NAS. The DS723+ takes advantage of AMD’s embedded Ryzen processor with higher core speeds. Intel will win with multimedia, but the AMD Ryzen is better elsewhere.

The AMD chip also brings support for error-correcting code (ECC) memory. Not only are you able to install up to 32GB of DDR4 compared to just 6GB inside the DS224+, but the memory will also be able to check data as it passes through to ensure there aren’t any errors present.

The Synology DiskStation DS224+ and DS723+ both have two drive bays, but the DS723+ supports an expansion unit and has two internal M.2 slots for NVMe SSDs. Then there’s the PCIe 3.0 x2 slot for installing an optional 10GbE module, which the AMD Ryzen R1600 processor will be able to handle.

The Synology DiskStation DS224+ is the more affordable NAS of the two and as such wins on price. Costing $300 without factoring in hard drives, the two-bay NAS offers good value and is only undercut by NAS from TerraMaster. The DS723+ comes in at $450, which isn’t a terrible jump for the improved specifications.

It’s not an easy process to choose the best NAS here solely on price, which is why we’ll cover design, performance, specifications, and other factors in this guide.


The design of just about every two-bay NAS from Synology is the same, aside from the j series. The Synology DiskStation DS224+ has the exact same chassis as the older DS220+ and there’s very little to tell the DS723+ apart from the DS720+. Both of these newer NAS look great and consist of an all-black look.

There are a few status LEDs on the front, a USB port, and a power button. The DS723+ uses Synology’s more premium drive trays with a locking mechanism. The trays on the DS223+ are more basic with push-button releases. Both enclosures make use of a single 92mm fan to handle all the cooling.

The top and sides are bare, but the DS723+ does have two removable doors underneath the enclosure for accessing the two M.2 slots. The rear of the NAS is a little strange since the DS224+ has three USB ports and the DS723+ only has one on the front. The latter does have the PCI slot on the rear, unlocking speeds up to 1,000 MB/s.

So which processor is better? Intel with its more cores and integrated graphics or AMD with its higher clock speeds? Regardless of which NAS you end up buying, both the DS224+ and DS723+ will be able to handle heavier workloads. This includes transcoding through Plex Media Server.

We’ve been able to enjoy stable experiences with either CPU transcoding heavy 4K files on the fly to various resolutions and formats. They’re also great at running other apps, including Synology’s excellent Surveillance Station. The DSM operating system also runs well across the board.

Where the DS723+ really takes off is with the ability to connect an expansion unit (the five-bay DX517) to the NAS, increasing the number of available drive bays from just two to seven. The two 1GbE ports on either NAS are capable of being linked with a single bonded connection providing additional bandwidth.

We were able to fully saturate the bonded connection without the CPU bottlenecking performance with either chip, meaning if you will primarily use the NAS for transferring data to and from the enclosure, both the Intel and AMD processors will work well.

Synology DiskStation DS224+ vs. DS723+

The Synology DiskStation DS224+ offers the very best of Synology in a complete package. It’s a tried and tested design with only a slight upgrade over the DS220+, namely the processor. This is one of the best NAS in terms of value and is what we’d recommend to those buying their first enclosure.

The Synology DiskStation DS224+ has ample performance for the price, allowing it to be used for creating a media server, surveillance station, and central hub for backups and general data storage.

You should consider upgrading to the Synology DiskStation DS723+ if you need a two-bay enclosure with a powerful processor, two M.2 slots, a PCI expansion slot for network upgrades, support for Synology’s expansion unit, and ECC RAM.

Synology’s DiskStation DS723+ is the better NAS for those with serious data needs. It’s better than the DS224+ in almost every way, aside from costing more and drawing higher amounts of power.
