QNAP Launches QM2 PCIe Expansion Cards for Adding M.2 NVMe SSD Slots to NAS or PC

QNAP Systems, Inc., a leading computing, networking, and storage solution innovator, introduced new QM2 PCIe Gen 3 expansion cards: the QM2-2P-344A and QM2-2P-384A. QM2 cards can be installed in compatible QNAP NAS or Windows®/Linux® PCs/workstations to add M.2 NVMe SSD slots (M.2 SSD sold separately) for boosting system performance and increasing storage capacity.

“The QM2-2P-344A and QM2-2P-384A are a budget-friendly expansion solution for both QNAP NAS and PC/workstations, providing flexible M.2 NVMe SSD configuration with easy-to-use tool-free installation,” said Andy Chuang, Product Manager of QNAP, adding “Compared with SATA-based SSDs, the QM2’s PCIe interface provides higher bandwidth to deliver faster transfer speed and data access.”

The innovative QM2 cards feature M.2 SSD thermal sensors that allow real-time temperature monitoring, and an efficient cooling module (heatsink and smart fan) to minimize overheating and ensure high performance. They can be used for SSD caching for IOPS-demanding applications or enable tiered storage in QNAP NAS for optimized storage utilization.

The QM2-2P-344A and QM2-2P-384A also support Windows and Linux, and are ideal for creating NVMe SSD storage volumes for performance-demanding applications such as video editing.
