Why consider this model?

  • A compact 1U reference to consider when four native SATA bays, two separate NVMe positions, individual 2.5GbE links and a documented owner-created RAID 1 option meet the rack plan. The non-RP configuration has one 250 W supply rather than the dual-supply h665U-RP arrangement.

Tradeoffs to weigh

  • The chassis has four native SATA positions and its built-in port ceiling is 2.5GbE per link; the extra NVMe positions are different media, while more bays or faster networking require separate expansion and compatibility checks. The one power supply lacks the h665U-RP's second supply. Exact drives/firmware, the seller bill of materials and rack rail/cabinet fit remain unverified.
