Why consider this model?

  • A narrowly suitable historical candidate for a project that needs a dense NVMe-heavy 24-position 2U system, no more than eight SATA-capable bays, and an individual 25GbE link; exact drives, OS/firmware, rack installation and legacy support must be confirmed.

Tradeoffs to weigh

  • QNAP marks the configuration Legacy. It is not a general 24-drive SATA NAS; the drive positions split 16 NVMe-only and eight NVMe/SATA. Exact SSD compatibility was not verified, the guide and current selector conflict on maximum memory, and rails are separate.
