Explore this buying guide ↗Why consider this model?
- A historical 3U rack reference where the project specifically needs the original SB2/QTS dual-CPU package, 16 front SAS/SATA trays, four separate rear SSD-only positions and an individual 10GbE link.
Tradeoffs to weigh
- QNAP marks SB2 EOL. Rear positions are SSD-only; the older guide and current spec differ in how slot/cache positions are counted and in PCIe slot count. Firmware, drive fit, support, service and exact seller contents require verification.
