I have a 4-bay Asustor nas and 4x3TB HDD's. As for now I do not require more than 3TB raw storage and run the nas in raid 1 with only two drives.
When I eventually want to increase my storage, I am sceptical to convert my volume to raid 5. Seeing the struggles involved with recovering data from an raid 5 array, I can't trust it as an option. I am more comfortable running two 2x3TB raid 1 array, since then I know that the data is formatted such that I can fetch it without rebuilding. Even asustor themselves does not have a method of recovering the data from an raid 5 array. I have been using snapraid before, and that is has been feeling more safe, as when a drive has failed, only the data on that drive has potentially been lost.
Am I paranoid and recovering from raid 5 data loss not that troublesome? can you recover data from a single drive that is from a raid 5 array?
