Why consider this model?

  • A fit for a desktop or small-team NAS plan that needs six conventional SATA positions and a built-in 10-Gbps Ethernet link without making a separate NIC the base assumption; it also has a documented owner-created two-drive RAID 1 option.

Tradeoffs to weigh

  • The 4-GB base is below the 8-GB minimum for QuTS hero; data drives and a configured array are not listed in the standard package. The compatibility view did not verify a particular disk, built-in M.2 drives are not hot-swappable, two Ethernet ports do not make one 20-Gbps client link, and the one PCIe slot makes any expansion-card choice a compatibility decision.
