![]() Even though you may lose a controller / enclosure, or software raid configuration, the drives can be placed in a new enclosure or hooked to a new controller and the raid configuration can be rebuilt. The RAID configuration is stored in metadata on the physical disks. Now, if I’m misunderstanding and you actually want two independent RAID 0 arrays, what I’m about to say, still applies in all circumstances. If you want maximum redundancy and performance you’ll need RAID 10 which comes at the largest cost because you can only use half the storage space available on the physical disks. They are both different than RAID 5 which is striping w/ parity. The two modes are different but essentially the same. What you describe….Two RAID 0 arrays where one backs up the other is called RAID 0+1 or RAID 10. Maybe there’s a little misunderstanding of RAID. ![]() What am I overlooking here? Is there something better to do with the 4 SSDs in terms of external storage? It somehow seems fishier to me, but the overall usable capacity would be larger. I guess I could also put the four SSDs into a RAID 5 array of about 12TB, where one drive could get damaged, but the array rebuild with a new one. I'd need to backup the mac to a third external drive, to be able to restore the system and thus software RAID setup and configuration? On the other hand, if the internal storage of my mac gets somehow corrupted or wiped, the software raid also goes out the window and the data is lost. I don't want a NAS for various reasons!Īs I understand it, if at one point the enclosure goes somehow bad and doesn't damage the drives in the process, the latter could still be transplanted into another enclosure, and used without needing to rebuild the array, right? The arrays would be managed with software, either Disk Utility, SoftRAID, or something else. OWC Thunderbay Mini), and buy two more 4TB SSDs to make two RAID 0 arrays of 8TB each: one would be for storage and the other for backing up the first. ![]() My plan is to get an external Thunderbolt enclosure with a minimum of 4 bays and no hardware RAID (e.g.
