This was easy to deploy, running as my Plex server and local backups.

This TerraMaster T6-423 was the answer to my storage needs, and will be for a long, long time. The ease of setup and use, as well as its massive storage capacity (6 bays, up to 20TB per bay) were perfect. And look how attractive the unit it. You can proudly display it on your desktop you'd like. Great NAS solution!

The drive trays are metallic and conductive. This is a problem if your drives have an exposed pcb as they could cause your drives to short out. OS sucks, best to use trueNAS or unraid. Hardware seems reasonable enough. Just wish the trays were plastic. I contacted customer support and they told me to use protective plastic? Not sure where I’m supposed to get that from so ended up costing the trays with plasti dip.

Works fine, was initially a bit unhappy with the RAM (non terramaster branded but 1/4 the price) and nvme drive I put in. Got into a weird state with the bios but has been fine since. The included OS isn't bad, but just runs MDADM linux raid under the hood. The TRAID is interesting but isnt ideal for performance (its just splits the disk into partitions, and then raids those together). It was always my goal to install Ubuntu server and run ZFS. 9x20TB drives raidz2 (raid 6) hits 1200MB/s before the cpu hits 100% and holds it back. Max you'll get over 2x2.5gbe nics is 500MB/s so no big deal. Its powerful enough for that easy.Would be nice to have a 10gb port but its $250-300 less than the competition and is essentially a regular PC board. Just pull out the internal USB drive, pop in an NVME ssd and set the BIOS to boot off that. Build quality is as good as most. Drive trays are fine. You can control the fans with the it87 module off the net in linux and the fancontrol app.

I purchased the 6 bay unit looking to create an array but after seeing some of the faults that the OS has it made sense to go with another OS.. there are guides on how to do this.. anyone with experience building computers can figure this part out... the issue i have with this device is the led indicator lights not going through the sata indicator and showing out of the front of the device to reflect the status. another thought would be the closeness of the drives being a possible factor. there is little space between the drive sleds and no padding to speak of when it comes to vibration that comes from the drives.

I've had this unit for a couple of weeks and I tore right into doing as much as I could with it. Here's a rundown of what you might want to know ahead of time.1) The software available off the shelf is serviceable. The app store is decidedly lacking in a choices, but there is generally something there to get you up and going in most of the areas you might be concerned with. After that, you will need to move to step 2.2) You will need to learn/know Docker, full stop. If you can't, you're gonna have a bad time. Probably a lot of the stuff you want to do is in Docker containers. Getting them to run is a mess. I don't know Docker, I'm having a bad time. Don't be like me.3) You can get in with puTTY and set up and run things but you will need to do more to get them to run outside of the account you log in with. I installed OpenJDK from Docker, then went in to the NAS through puTTY and set up a Minecraft server to see how well that would work and it runs great as long as the puTTY connection stays open. I'll be working on getting that to be permanent next.4) I put 32gb of ram in mine. Here is the exact set of sticks: https://www.amazon.com/dp/B08C511GQH?ref=ppx_yo2ov_dt_b_product_details&th=1The machine did complain and beep as loud as it could when I rebooted, which prompted me to shut it down and put a dot of hot glue over the buzzer hole, reboot, go into bios, save settings, reboot, and it booted right up after that. Don't be alarmed by the urgent beeping.5) You cannot build more than one array at a time, so if you fill this thing with 12 20tb drives in 6 sets of raid 1, you will be building arrays 6 times non-concurrently at over a full day each. Plan accordingly. In fact, you can't do anything while anything is happening to any array. If it is syncing, that's what its going to be doing until done, you cannot do any other disk operations until that is over.6) I put 2 solid state drives in raid 1, 1tb drives, and it took a very long time to build that 1tb array for some reason. I think it's that they are cheap ones and once the write cache ran out they run at somewhere around 15MB per second, very slow. Make sure you buy good ssd drives if you need high sustained write speed for large files.7) The only text editor I could find in the OS was Vi, so crack out that ancient command reference if you plan on doing any file editing in the OS. At least, until you get something else built to take its place.8) If the unit tells you it will take the disks offline to do an operation, be prepared for it to also disappear from the network for longer than you expect while it is doing magic disk stuff.So, if you are technically proficient in at least Linux, you should be able to get some stuff together and running on this NAS outside of what it comes with. I do wonder, though, if OS updates will wipe out any work you put into modifying files on the OS. Other than that, learn Docker. I like the machine.

The media could not be loaded.

What I like about it- It's compact- Comes with TOS 5 - (was easy to update OS)- Upgraded easily to 32G RAM w/ no issues (TEAMGROUP Elite DDR4 32GB Kit)- TOS could've been better, but for the price and capabilities, it's a great NAS.- I tested Unraid, TrueNas, and Windows 11! all work great as an OS alternative. (Maybe not windows as much)- Using Plex, I could max about 4-5 streams with (HW transcoding) and 5-8 with direct streaming. Testing in all OS. *Note: This will depend on the bitrate video file size so yours may vary.

bought this unit as all the reviews where good got it home booted it up worked fine, next day I changed hdd to bigger ones would not format or recognise disc sent ir back

I don’t like the. Entrusive spyware that the device runs in the background. Not sure why an internal network storage device would need to report back to a source the activity it has had on my network. Just not a kosher thing to do. Seems like a security violation on a secured network if you ask me. Anyway. I would not waste my good earned money on this one. It is compromised.
