QNAP QM2-2P-244A Dual M.2 PCIe SSD Expansion Card

Overview

The QM2-2P-244A is a PCIe expansion card that adds two M.2 SSD slots to compatible QNAP NAS enclosures, letting you deploy high-speed NVMe or SATA M.2 drives without consuming standard 3.5-inch drive bays. This matters in dense storage builds where every bay counts — adding SSD caching or tiered storage via the QM2-2P-244A keeps spinning-disk bays available for bulk capacity while the M.2 drives handle read/write acceleration. The card accepts both 22110 (110mm) and 2280 (80mm) form-factor M.2 drives, covering the most common NVMe SSD lengths on the market.

Compatibility

The QM2-2P-244A installs into the PCIe expansion slot of compatible QNAP NAS systems. Verify your specific NAS model supports a PCIe 2.0 or later x4 or x8 slot and that QTS or QuTS hero firmware recognizes the QM2-2P-244A before purchasing — QNAP's compatibility list on their product page is the authoritative source. This card is not compatible with non-QNAP systems or NAS units lacking a PCIe expansion slot. For surveillance-focused deployments, pairing this card with fast M.2 NVMe drives on a QNAP NVR or NAS-based recording system can provide the sustained write throughput needed for multi-channel 4K recording without taxing the primary drive pool.
