Why consider this model?

  • A four-position SATA enclosure for a home or small-office library that may outgrow two drives, especially when the buyer wants the documented choice of two-drive mirroring or four-drive SHR/RAID 5/6 layouts. It includes DSM sharing, backup and surveillance software, but its individual Ethernet ports are gigabit.

Tradeoffs to weigh

  • The DS423 has only 2 GB of non-ECC memory and no M.2 slots or expansion bay increase listed. Although it has two network ports, each is 1GbE; they do not promise one 2GbE client link. Drives are not in the listed package, and a four-bay chassis may be more capacity and setup than a two-drive plan needs.
