      1. The first thing I do with amy NAS is test data recovery. With TOS 5 I created an array of 8 TB, 4 TB, 1TB, and 500 GB. Deliberately extreme differences in sizes to test. My test swapping out the 4TB worked great. Recovery took 10 hours, but the system remained alive and fast the full time. However, attempting to swap the 500 GB resulted in a non-recoverable volume. I upgraded to TOS 6, but that could not recover the volume either. I need to test though to see if TOS 6 will actually create the non-recoverable volume.

        Pitty. Because I think I prefer TOS to unpaid. But if it cannot reliably serve it’s primary purpose of protecting my files, what is the point?

      2. Honestly, I’m a total noob to this nas stuff but comparing the f4-424 to everything else available in it’s price range has me quite interested in terramaster. The underdog aspect definitely helps too. You guys rock for nas info btw, I’ve been devouring your website for the past couple of days. Much thanks from Maryland, USA.

      3. 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.

      4. 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 ????

      5. 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.

      6. 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?

      7. 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?

      8. 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…

      9. 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.

      10. 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…)

      11. 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.

      12. 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

      13. 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
