I just spend almost 24h for data scrubbing to run on the new 2x 18tb drives in Raid1 with no data on them. While this was happening the CPU was at 0% all the time and I was not doing anything else on the NAS. The process is just as slow on another identical NAS running DSM6 Why speed up Linux software RAID rebuilding and re-syncing? Recently, I build a small NAS server running Linux for one my client with 5 x 2TB disks in RAID 6 configuration for all in one backup server for Linux, Mac OS X, and Windows XP/Vista/7/10 client computers.
