QNAP QM2 cards support either M.2 SATA SSDs or M.2 PCIe NVMe SSDs to enable SSD caching for boosted IOPS performance or to form an auto-tiering volume for optimal storage performance.
QNAP extended the lineup of QM2 PCIe expansion cards with new models that support up to four M.2 SSDs slots on a single card. QM2 cards also allow QNAP NAS users to maximize both storage capacity and performance by installing M.2 SSDs without occupying any 3.5-inch drive bays.
“When faced with a performance bottleneck, the random read/write speed of the hard drives in a NAS is one of the decisive performance factors,” said Joan Hsieh, Product Manager of QNAP, continuing “QM2 cards can greatly boost the performance of QNAP NAS with PCIe slots, while the flexible configuration of SSD caching and I/O-aware Qtier all helps multiply NAS performance.”
