QNAP QM2-2P-344A Dual M.2 NVMe PCIe Gen3 SSD Expansion Card
Overview
The QM2-2P-344A is a dual M.2 PCIe NVMe SSD expansion card that slots into a compatible QNAP NAS PCIe slot to add two NVMe SSDs without consuming drive bays. Running on a PCIe Gen3 x4 interface, it delivers up to 32 Gbps of aggregate bandwidth — enough headroom for SSD cache tiering or a dedicated NVMe volume on a multi-user NAS deployment. No drivers or additional software are required; the card is recognized immediately on supported QNAP firmware. This is the right component when you need fast SSD cache or a dedicated NVMe storage pool on a NAS storage appliance and want to preserve all spinning-disk bays for capacity.
Compatibility
Designed for QNAP NAS models with an available PCIe Gen3 x4 (or wider) slot. Accepts M.2 NVMe SSDs in 22110 and 2280 form factors — the two most common enterprise and prosumer NVMe lengths. SATA M.2 drives are not supported; the slot is NVMe-only. Verify your NAS model's PCIe slot availability and lane count against QNAP's compatibility list before ordering, as PCIe Gen2 hosts will operate at reduced bandwidth. For guidance on pairing expansion cards with the right NAS platform, see the NAS accessories category.
Installation Notes
The card ships with a low-profile bracket installed by default; a low-profile flat bracket and a full-height bracket are also included, covering both desktop tower NAS chassis and rackmount enclosures with standard PCIe slot openings. Seat the card fully into the PCIe x4 slot, secure the bracket, install your M.2 NVMe drives into the card's two slots (supporting 22110 or 2280 lengths), and power on — no driver installation step is required. Confirm slot compatibility with your specific QNAP NAS model before installation, particularly on rackmount units where low-profile clearance is mandatory.
