23 thoughts on “Terramaster TOS 6 NAS Software Beta – Now Available

  1. Can you compare Terramaster directly with Asustor. Newer NAS OSs but great hardware for price. See how each has developed the software over the years and if its worth buying into either ecosystem.

  2. I’d be very cautious about using the 6 Beta. Seems like it corrupted my USB Boot Chip and they are sending me a new one. Comment was made at first that I should pay for it ????. Seems they will send it for free now. Perhaps I should have paid extra in the beginning for a Synology as my Terramaster has been a pain since I bought it ????

  3. Upgraded to 6. All looked good until I realised all my folders had disappeared. Tried creating a shared folder but it wouldn’t have it. Tried good old turn it off and on again by signing out and then it kindly permanently locked me out. The NAS shows up on TNAS Uninitialised but it won’t fire up to the sign in page/boot/initialisation ????. Tried all I know so having to let Terramaster remotely control my PC/ NAS tomorrow as I don’t know anything about getting into its brain via terminal mode etc.

  4. I have the F4-423, it would be really awesome if they could get something as basic as rSync or any sort of backup service to work reliably. Hey, there’s hope!

  5. would love to hear your thoughts on a comparison between TRAID with mixed sized drives and SHR/SHR2 with mixed drives, does terramaster do data scrubbing too?, also heard some of the big terramasters (12 bay) have metal caddies, is this dangerous for the bare PCB on drives?

  6. Is raid 5 work for any drives number, like it will use 1 drive for even 20 drive in the raid?

    Or is it a ratio, like every 4 drives, 1 drive is parity/ redundancy or whatever they call it?

  7. How the heck do you enable data scrubbing? It was a no brainer in TOS 5.x I just got my Terramaster so I updated on Day 1. I like TOS 6 and the top bar too.

  8. That OS is so beautiful and clean I want to switch from Synology. Just hesitant after their nas units were hit with ransomware a few years ago

  9. Nice to see the windows staying live and not having to go blank and transparent when moved around. Not a biggie but it makes the Synology UI look very outdated.

  10. Well, TRAID+ was my motivation for getting a TerraMaster system, and they’ve finally removed all references to TRAID+ in their documentation… the hardware is fine, but I definitely feel that I experienced a ‘bait-and-switch’.
    If TRAID+ was included in TOS 6 Final, that would help, but I suspect that TRAID+ won’t appear until TOS 10 at the earliest…

  11. Really pleased to see this from TerraMaster, even though I presently run Qnap TS-855X. Terramaster turns up the heat to further move QNAP along on the software side!

  12. Thank you for making my life easier ????

    Please may we have a list of NASs that you can load your own OS onto?

    Maybe it would make an interesting video?

    I have a Terramaster F2-423 running Proxmox and it is solid.

  13. I am still waiting for the day when a NAS brand doesn’t spend unnecessary development time on useless features that much worse than open-source counterparts… (Yes, I am looking at Synology, and that horrible abomination they created as a “docker” manager…)

  14. I do like terramaster, but has anyone tried to find the android mobile app on playstore for photo uploads, dosen’t exist?
    Its a deal breaker for me.

  15. Yeah, for beta, it looks good IMO. Also of note Ugreen has some interesting NAS hardware on the horizon. Like with other NAS offerings that are not Synology the Ugreen software and OS is a bit S#!t but it’s still worth a look.

  16. They have hdd icons for ssds. That shows lack of attention to detail. Since might say it’s not important, but for me it’s a red flag. Lack of attention to detail in one area may signal similar lack in other, less visible places.
    Also, we need a list of shame for ui designers that make small dialog windows which require scrolling when there’s a lot of free screen real estate

  17. Lets have a look what they got

    Currently have their 6bay running unraid ( like how unraid work as it got less drive spinning when access )

    And a teramaster 6bay usb DAS connected to it

    Consider get one more unit if their TOS got interesting function added in new version
