QNAP QXP-820S-B3408 2-Port MiniSAS HD HBA, PCIe 3.0 x8

Move SAS storage traffic onto a compact adapter built for rack systems where space is limited and throughput still matters. The QXP-820S-B3408 is a 2-port MiniSAS HD host bus adapter with a PCIe 3.0 x8 host interface and a 12Gb/s SAS controller, giving compatible systems a direct path to high-speed storage connectivity. Its low-profile, plug-in card design makes it a practical fit for dense servers and storage appliances that cannot spare full-height expansion hardware. That matters in production environments where chassis clearance, airflow, and service access all influence the final configuration. Instead of forcing a compromise between performance and fit, this adapter is built to slot into the system cleanly. For teams standardizing on QNAP infrastructure, the adapter supports storage expansion and external SAS attachment with the kind of physical profile that belongs in serious rack deployments. It is a targeted component for environments where the cost of downtime or a bottleneck is higher than the cost of the right adapter.
