I have a RAID 5 that I'm expanding from three 12 TB drives to four 12 TB drives. As I wait for the new hard drive, I am copying all the data to some external drives, in case something goes wrong. I remember that when I set up the array, it took about twenty hours. So, which is faster?
Expanding the RAID through the normal process.
Wiping the RAID, starting it over from scratch with four drives instead of three and moving all the data back.
