QNAP QDA-A2MAR 2.5" SATA to Dual M.2 2280 SATA Drive Adapter

Overview

The QDA-A2MAR is a drive adapter that converts a single 2.5" SATA bay into two M.2 2280 SATA slots, letting you populate otherwise unused bays in compatible QNAP NAS enclosures with M.2 SATA SSDs. If you have empty 2.5" bays and want to add fast SSD-based storage pools — for caching, tiering, or dedicated application volumes — without purchasing an additional expansion unit, the QDA-A2MAR is the targeted solution. The adapter accepts two M.2 2280 form-factor SATA SSDs simultaneously, effectively doubling the drive count from a single bay slot.

Compatibility

The QDA-A2MAR is designed for NAS enclosures with 2.5" SATA bays. Compatible enclosures include QNAP TS-series and TVS-series units that provide accessible 2.5" SATA drive slots — confirm your NAS model supports 2.5" SATA drive trays before ordering. The adapter accepts M.2 2280 (80mm) SSDs running the SATA protocol only; M.2 NVMe drives are not compatible with this adapter. If your QNAP unit features dedicated M.2 slots, those are separate from what this adapter addresses — the QDA-A2MAR is specifically for repurposing standard 2.5" bays.
