Plugging them into the 2 separate thunderbolt ports on my late 2013 iMac puts them onto different busses, correct? You're just specifying ports to refer to the daisy chain scenario? I thought that the 2 Thunderbolt ports would be on 2 different busses. And even if not, why/how would that affect redundancy of the external Thunderbays? Sorry if I am misunderstanding you here.
There is one thing we should clarify, so you understand what you have. A RAID 1+0 is essentially a 2 or 4 drive stripe, with the additional 2 or 4 drives mirrored to each one. This is why you can remove an enclosure and the volume will mount and why it can rebuild. The caution is that when you remove the second Thunderbay, you are operating from a RAID 0 (stripe) volume which is not secure. If a disk fails when the others are missing, you lose data. (although the backup would be mountable!)
Right, I understand a 4 disk RAID 0 is a bit risky as far as data loss, but in my situation it would only be temporary until the other Thunderbay returns (no more than a day or two probably). And as you said, the other one would still mount and work as a "backup" so there wouldn't be any data loss as long as there wasn't new data on the host computer during the time I was running as a RAID 0, or the data loss would be limited to that recent data. And without drive failure, I can just plug the 2nd ThunderBay back in and it would rebuild from the 1st Thunderbay's new recent data, correct? But that brings me to my last question which is just to verify what options I have for mounting SoftRAID volumes in situations like these, namely on different computers: 1) If I move a RAID 1 array to a computer without SoftRAID, is it at least readable? Or would it not mount at all? Is writing possible at all given that writing to one of the disks could theoretically work, though it wouldn't be mirrored to the other disk? 2) For RAID 0 and RAID 10 situations, moving a device from one computer to another requires them both to have SoftRAID for either reading or writing? For example, in the use-case scenario I outlined above, moving 1 of the 2 Thunderbays (making it a 4 disk RAID 0) to another computer requires that computer to have SoftRAID installed for it to mount at all or be read at all? I know it's required to write, and I'm assuming you would need SoftRAID to read that array as well, correct?
