Does rebuilding RAID array erase data?
Even if two RAID disks go down, you have nothing to worry about. If you do not have any backup, be sure to use RAID Recovery software to recover data from a damaged RAID disk. Because after rebuilding a RAID 5 array, the data will be overwritten; i.e., it will disappear forever.
Can I change RAID without losing data?
Storage pools can be changed from one RAID type to another without losing existing data. For example, you can create a RAID 1 storage pool on your Synology NAS and later change it to RAID 5 if you install more drives.
Can you use RAID while rebuilding?
Yes, you can use it, it'll underperform obviously and the harder you thrash it the longer the rebuild might take but by all means use it - that's kind of the point of R1 isn't it. I'd be correct in saying RAID 5 and 6 also apply to this, yes? Correct yes, exactly the same.
