I currently have a NAS with 4 drive bays with 4x4TB drives in a RAID 10 but I’m running out of space. I have two 12TB drives I would like to use to increase the capacity of the pool but I’m not sure on the best method of upgrading the drive sizes without an extra slot to add the new drives to the pool before removing two of the older 4TB drives. I do have an external hard drive enclosure I can plug into the NAS via USB but not sure if adding the drive to the pool that way before removing one of the others is a good or bad idea as the drive name will change once moved into the actual NAS.
Any help would be appreciated
