Synology DS923+ vs. QNAP TS-464: Which NAS is best?

Synology and QNAP make plenty of network-attached storage (NAS) enclosures and the Synology DiskStation DS923+ and QNAP TS-464 are powerful models with a similar market. If you’re looking between the two for your next home server, which one is best? In this guide, I’ll compare the two NAS to help you make the right decision.

  • Powerful AMD CPU
  • User-friendly OS
  • Upgradable RAM
  • More expensive
  • No HDMI output

The new DS923+ from Synology replaced the popular DS920+ with an all-new AMD Ryzen processor. It’s still a good pick for running a media server, but it’s not quite as capable as the QNAP TS-464.

  • Powerful Intel CPU
  • Cheaper MSRP
  • Same excellent OS
  • HDMI port and solid expansion
  • RAM cannot be expanded

Looking at the QNAP TS-464 specifications alone makes it appear to offer better value than the DS923+. Excellent expansion support with a PCI slot, M.2 slots, and superfast networking exists.

QNAP manages to undercut the Synology DiskStation DS923+ with its TS-464 while offering better specifications for the price. The QNAP TS-464 has an Intel Celeron processor that’s slightly more capable than the AMD Ryzen chip found in the DS923+, especially for tasks such as video transcoding. A major win for QNAP is the fast networking and better expansion support.

It’s not all bad for the DiskSTation DS923+, however. Synology does allow for up to 32 GB of DDR4 RAM to be installed, though only 4 GB is preinstalled at the factory. The Intel Celeron N5095 inside the TS-464 can only handle 8 GB. I’m a fan of both Synology’s DSM and QNAP’s QTS operating systems, though Synology’s cloud infrastructure is well-established with better functionality.

Which NAS is better for you depends on what you plan on using the connected storage for. If it’s for transcoding a lot of media and you’re working with larger files, the TS-464 with its quicker networking and Intel chip may be the better option, though Synology’s DS923+ is no slouch with the upgradable RAM and dual-fan cooling solution. Both enclosures are excellent storage boxes.

Powering the Synology DiskStation DS923+ is an AMD Ryzen R1600 processor. Synology is slowly making the switch to AMD chips with its more powerful enclosures and this dual-core CPU is capable of hitting speeds of up to 3.1 GHz. It may not have fancy integrated graphics like the 4-core Intel Celeron N5095 inside the QNAP TS-464, but it has better per-core performance.

The DS923+ has 4 GB of DDR4 RAM out of the box compared to QNAP’s 8 GB with the TS-464. The latter does not support system memory expansion whereas the DS923+ can handle up to 32 GB, though you’ll likely never need that much on your NAS. Both NAS have four drive bays and as such support just north of 80 TB, depending on the configured RAID.

Connectivity is where the DS923+ and TS-464 differ the most. QNAP went all out with two 2.5 GbE ports, four USB-A ports, and a HDMI port you can use for consuming media. The DS923+ has just two USB-A ports, two 1 GbE ports, and eSATA. To the average Joe, this won’t seem like a huge difference, but if you’re looking to push the NAS hard, you may encounter bottlenecks with either NAS. I d didn’t have any trouble running popular apps on either NAS.

Design and features

The Synology DiskStation DS923+ looks identical to any other tower NAS from the brand. It’s a large black slab of plastic and metal with some subtle branding on the sides. The four drive bays are easily accessed from the front and one of two USB-A ports is also front-facing for convenience. The QNAP TS-464 has a more striking design with a gold strip on the right side of the front panel, hosting the LED indicators, USB-A port, and power button.

The drive bays are hidden behind a removable panel, which is magnetically attached to the chassis. It’s a stunning piece of kit and looks more premium than Synology’s more simplistic design. The QNAP NAS has a dedicated PCI slot that can be used to upgrade the networking or storage capacity. Two M.2 slots are available inside both NAS devices for improving performance through data caching.

The Synology and QNAP NAS enclosures have powerful and feature-rich operating systems. DiskStation Manager is my favorite prebuilt NAS OS and comes with every Synology enclosure. It’s easy to use, resembles a traditional desktop OS, has numerous apps available, and is supported by a powerful cloud ecosystem. QNAP’s QTS isn’t too far behind and has plenty of apps available, but it falls short of what Synology offers.

Inside the QNAP TS-464 is the powerful Intel Celeron N5095. While this four-core CPU may not be able to match what’s being installed inside desktop PCs, it’s perfect for a NAS. With Intel UHD Graphics, the N5095 can handle media transcoding as well as file storage, making the TS-464 a versatile enclosure. Running the latest version of QTS, I managed to use the TS-464 for streaming media, running a surveillance system, and even automatically storing backups.

Synology made the switch to AMD Ryzen processors for some of its enclosures. These aren’t the same as AMD Ryzen desktop-class processors, but they’re still great for servers such as the DiskStation DS923+. Looking at the Synology DiskStation DS923+ vs. QNAP TS-464, you won’t be able to tell the difference in the performance of the hardware. It’s only when you want to run multiple heavy processes simultaneously can the DS923+ with its 32 GB RAM capacity makes more sense.

Synology is one of the more popular brands for NAS enclosures and that’s for a very good reason. The company makes excellent hardware and software, which when combined offer the best user experience. That said, you may find its NAS falling behind the competition with specifications, and this is certainly the case with the QNAP TS-464. The DS923+ is still a solid NAS.

Go with the DS923+ if you need more horsepower from your NAS. With the ability to install up to 32 GB of DDR4 system memory, this powerful server can handle more intensive workloads.

The QNAP TS-464 is cheaper than the DS923+, at least with a direct comparison of the MSRP. It also has some beefy specifications, including a PCI slot, 2.5 GbE networking, and a powerful operating system. Its design is also more appealing than a simple slab of black plastic. There’s even a HDMI port on the rear that can be used for consuming media.
