The Flexible Disk Array -- TerraMaster TRAID

[Gremlin]

Hey, Can I move a TRAID disk into another (Terramaster) NAS using a newer TOS from the one it was created?

If you mean a single disk of a TRAID array, no, I don't think so. TOS is a mirrored raid array [Raid-1] containing the operating system and other basic system requirements. Adding a "non-matching" disk will create problems with the basic array(s) [mirrored partitions] holding the operating system.

In case of hardware failure, can I replace the NAS with a newer TOS and keep the disk array and data?

As above, you may be misunderstanding the TOS arrangement. You could obtain a matching or compatible NAS (check specs and get TM advice if needed) without disks and mount the TRAID disks in it. It will then boot from the established array(s) and will run whatever TOS version is on the disk array.

Could not find any specifics, only benefits/cases mentioned with 5 drives.

Is there any benefit of using TRAID witht only two drives in an two bay housing (F2-220)? Like: Can USB drives be included in TRADE or something?

Can I read the drive data in an emergency case on another linux system when using TRAID with only two drives (like with raid 1)?

Basically Intel based devices are not compatible with ARM based devices and vice versa. These are the 2 main varieties of TM nas.

You can of course use Traid in 2-bay device (I do). I also have a 5 bay (same base), so should the need arise I could move my 2 drive array to larger device and expand the Traid. Obviously, you can't go from 4/5 bay to 2bay if the array occupies more than 2 hdd.

No. Basically you cannot read any TOS drive on any other operating system because of the way the OS is arranged. {NB: Simplified explanation}
