I have a client that needs more space on the NAS. I have two options and would like to know what you guys think is the better option.
Option 1
upgrade the existing 5 drives in the DS1618+ (new 8TB drives, currently 3TB drives) to larger disks to create the needed space. Using SHR for the formating and Btrfs.
Option 2
Attach a new DX517 5-Bay Expansion Unit to the DS1618+ with 6 6TB drives to create the needed space.
With the different drive prices, it comes to within a few hundred dollars to do either update. What do you think will be the best way to go? It seems to me upgrading the existing drives would take longer for the rebuilds than the expansion unit setup but less hardware to worried about crashing. Also, increased risk when upgrading drives and adding them into the existing Volume, if something did go wrong? I have good backups. Maybe I am missing something else, if so let me know.
