I saw someone using Raid0. Please realize that Raid0 provides NO redundancy against data loss. Regardless of the number of drives employed in a Raid0, if one drive fails, then all data is lost. Always deploy, at a minmum, Raid1 which mirrors 2 like sized drives or better yet, Raid5 which employs a minimum of 3 drives up to 5 or 6 in small deployments. Then remember to back all data up using a cloud based solution like Carbonite, iDrive, etc.
I use RAID 0 to aggregate a pair of 3 TB drives into one logical 6 TB drive. I am not concerned with fault tolerance. I have incremental backups run every hour to a 10 TB external drive, a 2 TB monthly mirror of my images & critical data files and my images stored on Amazon Photo.
If I lose one of my RAID 0 drives, Easy enough to get to the back up data instantly, to use or restore it to another drive in my Probox external multi drive box.
When my WD duo craps out, or I lose one of the 3 TB drives in the array, I will simply pick up another 8-10 TB drive for my Probox and restore from my Time Machine disk, no harm no foul.
As I mentioned, backups need a tested plan confirmed to work.
