The DS420J is a n-1 redundant storage system. This is similar to RAID5 from the old server era. This means the NAS can tolerate one disk failure. It is advisable to have one spare disk to replace a failed disk. Resilvering can be slow with consumer disks but server class disks are faster.

The unit is easily setup with a browser based interface. The DS420J can be setup with 3 disks initially and an additional disk can be added subsequently.
