QNAP QM2-2P-384A Dual M.2 NVMe PCIe SSD Expansion Card

Overview

The QM2-2P-384A is a dual-slot M.2 NVMe SSD expansion card that slots into a compatible QNAP NAS PCIe bay, adding two M.2 drives without consuming any 3.5" bays. If you're building out an SSD cache layer to accelerate a spinning-disk NAS array — or provisioning a dedicated NVMe volume for a high-IOPS workload — this card is the direct path. The PCIe Gen 3 x8 interface delivers up to 64 Gbps aggregate bandwidth, enough headroom for both NVMe slots to run near peak without the interface becoming the constraint. No drivers or additional software are required; insert the card, seat the SSDs, and the NAS OS recognizes them on boot. Both 2280 (80mm) and 22110 (110mm) M.2 form factors are supported, so you have flexibility in drive selection. Use the installed SSDs for SSD cache to reduce latency on a traditional HDD volume, configure them as a standalone NVMe RAID volume, or combine both strategies depending on your NAS storage architecture. The QNAP QM2-2P-384A also supports multi-OS environments, making it functional in systems running the card outside a NAS context.

Compatibility

The QM2-2P-384A is designed for QNAP NAS systems with an available PCIe Gen 3 x8 (or wider) slot. Compatible host systems typically include QNAP TVS-h series (e.g. TVS-h877AX, TVS-h1288X), TS-x73A and TS-x77 series, and other QNAP tower and rackmount NAS models with a PCIe 3.0 expansion bay. Always verify slot availability and PCIe lane allocation in the specific NAS model's hardware specification before ordering — some units share PCIe lanes across multiple slots, which can affect available bandwidth. Drive compatibility depends on the M.2 NVMe SSDs installed; SATA M.2 drives are not supported. Refer to QNAP's official SSD/HDD compatibility list for validated drive models. Pair with a compatible NVMe SSD and a PoE or managed switch appropriate for your NAS network throughput requirements.

Installation Notes

The card occupies a PCIe x8 slot. Confirm the host NAS is powered down and properly grounded before installation. M.2 SSDs seat into the card's two slots and are secured with the included retention hardware — no additional tools beyond a standard screwdriver are required. No driver installation is needed under QNAP QTS or QuTS hero; the drives appear automatically in Storage & Snapshots for configuration. If deploying as an SSD cache, review QNAP's cache acceleration documentation to size cache capacity appropriately relative to your working dataset — undersized cache on a large spinning-disk pool delivers minimal latency benefit. A NVR or storage-intensive application pairing benefits most from the dedicated NVMe volume configuration rather than cache mode.
