F6-424 NAS Storage 6Bay - N95 Quad-Core CPU, 8GB DDR5 RAM, Dual 2.5GbE Ports, Network Attached Storage with High Performance (Diskless)

I got this to upgrade from a Synology 2-bay NAS. It is pretty good hardware for the price, relative to other appliance type NAS devices. Inside there is a very small USB drive that holds the Terramaster OS, but if you remove that you can install something else - this does involve disassembling it though. I put TrueNAS Scale on it right away, so I can't speak to the stock OS, but I have had no issues with TrueNAS compatibility. The N95 processor is very efficient and the unit stays pretty cool, but if you want to run a ton of containers you might need something with more processing power. Overall a good piece of hardware with a lot of bays.

Honestly, I don’t know anything about these (NAS). An IT buddy of mine is the one that recommended it. It works perfect with Plex for watching movies TV shows, etc. And you can use any hard drives unlike some other brands. Compact in aize (6 day) too!

UPDATE: I’ve owned four TerraMaster units over the years, so I went into this F6-424 with high hopes especially after upgrading it right away with maxed-out RAM and dual NVMe drives for caching/system. The hardware itself feels solid on paper: 6 bays, decent CPU, tool-free trays, hot-swap support, and the ability to handle large drives. But in real-world use, this has been a letdown and feels like a step backward from even my older TerraMaster models. The biggest frustrations stem from the proprietary TOS 6 software and TRAID RAID system. Configuring the storage pool is painfully slow and cumbersome as you have to add hard drives one at a time, and each addition triggers a full synchronization/rebuild process that takes multiple days (often 1–3 days per drive, depending on size and capacity, with large 14–20TB drives pushing toward the longer end). Even with all six bays eventually filled, the initial setup and any expansions dragged on for what seemed like weeks of waiting, during which the NAS is noisy, resource-heavy, and often unresponsive in the interface. After configured and connected to my 2.5GB LAN and 1GB WAN, performance remains surprisingly sluggish for file transfers and operations despite the upgrades and the system is temperamental with random notifications or issues needing reboots/tweaks to stay stable. To me, TOS 6 feels even more proprietary and locked-down than previous products, with fewer flexible options and heavy reliance on TerraMaster’s ecosystem (TRAID, their apps, etc.). It reminds me of clunky tech from the early 2000s: inconsistent behavior, no real polish, and way too much babysitting required. At this price point, I expected smoother operation out of the box, better optimization, and far less downtime during setup/expansion. The hardware has potential, but the software holds it back badly. I can't advise on alternatives as I've invested so heavily over the decade+ in TerraMaster products, At this point I will look elsewhere. This is my fourth TerraMaster, and unfortunately, it’s pushing me to move on entirely. Pros (to be fair): Easy physical upgrades (RAM/NVMe) Good build quality and 6-bay count Hot-swap support works well Cons: Extremely slow and multi-day synchronization when adding/configuring drives one by one in proprietary TRAID Sluggish and unreliable performance even fully upgraded Overly proprietary OS with limited flexibility Feels outdated and overpriced for what it delivers Requires constant maintenance/tweaks to keep running smoothly If TerraMaster dramatically improves TOS in future updates (especially TRAID setup times and stability), maybe it could redeem itself but right now it's disappointing for the cost and marketing hype.

If all you are doing is network storage or Plex direct play, this thing does fine. But, if you are needing any type of transcoding above 1080p you can forget about it.

Es un gran equipo, funciona increíble para almacenamiento de mis películas muy rápido, muy facil de usar 100% recomendado si no te quieres gastar un dineral en un NAS de 6 bahías.

PROBLEM #1: No network!!! Imagine previously having had another Terramaster NAS which worked as advertised. Not perfect, but acceptable. Then, you buy this pricey NAS, you power it on (after searching and finding the unusually positioned tiny power button), and all you get is periodic beeps. Your router does not see the NAS on the local network, and this NAS never requested an IP address from DHCP. A NAS without network access is just an expensive paper weight, there is nothing that can be done with it. Then you contact Terramaster support, and they say, hmmm, the memory may be loose, open up the NAS and move the memory stick to another slot?????????? How many people are comfortable to do this?? Also, doesn't opening the box void warranty? First support promises a quick replacement, but then keep putting up more hurdles before you can get a replacement. What happened to quality control? The way support answered, there seem to be quite a few units like this, and I can imagine the deluge after Black Friday. Bottom line, I expected a lot more from a German product, also based on my experience with previous Terramaster products. But in the end, you get what you pay. For me, data loss is not a joke so I am going back to Synology. Yes it's more than twice the price of Terramaster, but you get a serious, mature, rock solid NAS that will protect your data. Also, consider that none of the Synology NASes went on sale during Black Friday/Cyber Monday - there must be a reason like high demand. PROBLEM #2: No documentation whatsoever. And you have to give your email address to just get the installation manual. Problem #3: There is no Reset pin hole on this NAS. So how are you supposed to reset it??? Who knows, there is no user manual. UPDATE #1: I forgot to mention, their Android App called TNAS crashes within 3 seconds of launching, every single time. Terramaster, do you test anything before releasing? I have until end of January to return this poor, sad product.

Terramaster is a nice NAS system. Hard to get things going at times but a great user community to get help

Decided to get a non-max version of the F6-424 since the price difference is huge and I probably wouldn't need the extra compute power. Even though this one with the N95 processor is supposedly limited to 16gb of ram maximum (as per Intel), I was able to replace the 8gb stick with a 32gb no problem (note: this one has one ram slot as it is single channel, the max has two and supports dual channel) It was also a breeze to flash the 4gb usb stick with TrueNAS Scale installer using rufus on Windows, after minor tear down to take out the USB for flashing. TrueNAS Scale loves ram so I'm really happy it's able to use the 32gb no sweat.

This NAS is not for people already experience using Synology, QNAP, or Truenas. Simple task like remote mount from or to other nas device is nightmare to setup and 99% it would not work. SMB is totally useless when comes to remote mounting. I only manage to NFS working for Qnap. Even I successfully mounted, it will not allow you to copy files from the search result. You will need to go actual folder of file and copy from there. I guess there is reason why they allow you to install 3rd party OS since their TOS 6 still a mediocre OS

Outstanding service! The NAS from Terramaster is incredibly fast and reliable. The staff is knowledgeable and friendly — truly a great experience. Terramaster delivers performance and quality you can count on
