TerraMaster makes a few solid NAS enclosures and the F2-223 and F2-423 are what you will be considering when looking at a two-bay NAS server. This guide will run you through all the specifications of the TerraMaster F2-223 vs. F2-423 and which NAS you should purchase.

  • More affordable
  • Still has an Intel CPU
  • Two M.2 SSD slots
  • Good TOS OS
  • Less powerful CPU

The TerraMaster F2-223 is a solid good value NAS with an Intel CPU, M.2 slots, and 2.5GbE networking. It’s great as a starter NAS for running Plex Media Server and other intensive apps.

  • More powerful Intel CPU
  • Two M.2 SSD slots
  • Good TOS OS
  • More expensive

Should you require additional power, there’s the TerraMaster F2-423. This NAS has an uprated Intel CPU, which adds an additional two physical cores and allows for more to be done without encountering a performance bottleneck.

Choosing between the TerraMaster F2-223 vs. F2-423 is actually an easy decision to make. Do you need the most powerful of the two enclosures? The TerraMaster F2-423 would be the NAS for you. But if you’re happy with the same specifications, aside from a slightly weaker CPU, we’d recommend the TerraMaster F2-223.

TerraMaster F2-423 is a more powerful NAS

When recommending the best NAS, we’d always suggest enclosures with an Intel processor, unless it’s for those on the tightest of budgets. That’s the only difference between the two NAS. The weaker and more affordable TerraMaster F2-223 comes with an Intel Celeron N4505 processor. This chip has two cores and a clock speed of up to 2.9GHz.

Then there’s the TerraMaster F2-423, which comes with the Intel Celeron N5095. This may not sound like such a jump from the F2-223 and it may have the same 2.9GHz burst, but there are double the number of cores. This allows the F2-423 to do much more at once and power through intensive tasks easier than the F2-223, but both chips are excellent.

Both NAS enclosures have 4GB of DDR4 RAM, which can be expanded to up to 32GB, which is more than what most desktop PCs come with. Two drive bays are available with two M.2 slots for caching NVMe SSDs. Raw capacity comes in at 40TB, but this will vary due to the selected RAID setup.

The TerraMaster F2-223 and F2-423 have the same ports on the rear of the two NAS, which consist of DC input, HDMI, two USB-A 3.1 ports, and two 2.5GbE network connections. That’s a lot of bandwidth, offering transfer speeds up to 480MB/s.

Buy the TerraMaster F2-223 to save money

The two NAS look almost identical, aside from the model number stick on the front with the two drive bays. We’re suckers for the design of these enclosures, which resemble more of a classic look. It’s also a welcomed departure from the usual black slabs of metal and plastic from competing brands.

The choice between the TerraMaster F2-223 vs. F2-423 is an interesting one as both enclosures are incredibly similar. Regardless of which NAS you opt to buy, you’ll be able to run Plex and transcode 4K content, and store just about anything from multiple devices. So long as you don’t need more than 40TB, you’re good to go.

Where the TerraMaster F2-423 comes into play is when the dual-core Intel Celeron simply won’t cut it. If you’d like to do more than simply running Plex or having a few people store and access files, we’d recommend going with the more powerful NAS for running multiple services at once.

Two drive bays, an Intel CPU, an HDMI port, and upgradable RAM make the F2-223 a killer NAS that creates problems for the competition.

With two M.2 slots, 2.5GbE networking, and a capable dual-core CPU, the TerraMaster F2-223 is a solid workhorse that’s only let down by the limited storage capacity and processor performance. It’s affordable and powerful enough for running Plex.

The F2-423 is simply better with the uprated processor. It doesn’t cost too much more than the F2-223 but is worth it if you need the extra power.

There’s no real reason to choose the F2-423 over the F2-223 unless you require the extra processing power. It also has the same M.2 slots, HDMI port, 2.5GbE networking, and TerraMaster TOS operating system.
