You have 2T, no redundancy.  No RAID is backup - but RAID 0 has no redundancy, either (i.e., if either drive fails, you lose everything on both drives).

With RAID 0, it means that you have 2TB of storage [1862.6GB].

thanks for the prompt replies. I'm struggling to understand the benefits of raid unless they back each other up. As you say, if one goes wrong you lose both, how can that be better than just having 2 normal 1tb drives?

I stopped using RAID several years ago, because a RAID-0 failure could really ruin my day and with RAID-1, the one problem I've found. is that whenever there is any software corruption, or a virus/malware problem, it's mrrored to the second hard drive of the array.

Went to using two hard drives and an imaging utility, like Acronis daily, to image the C:/ drive to the second D:/ hard drive.

Now whenever there's a issue, all I need to do, is to open the case and swap the data cables, boot the system and image the new C:/  to the corrupted second  hard drive, creating a corrupt free image again.
