Add Dual M.2 SATA SSDs with Hardware RAID in a Single Bay

The QNAP QDA-A2MAR adapter allows two M.2 2280 SATA SSDs to be installed in a single 2.5-inch SATA drive bay, supporting multiple hardware RAID modes without consuming host system resources. Compatible with Windows, Linux, and QNAP NAS systems, the QDA-A2MAR provides an affordable, high-performance, and RAID-protected SSD storage upgrade for desktops, workstations, and NAS.

Highlights

• Supports two M.2 2280 SATA SSDs in one 2.5-inch SATA drive bay

• Up to 6Gbps file transfer speeds with bootable drive support

• Hardware RAID modes: RAID 0, RAID 1, JBOD, Individual

• Tool-free RAID configuration via onboard DIP switch

• Compatible with Windows, Linux PCs, and QNAP NAS

• Includes External RAID Manager utility for Windows

• Sold as a single unit for flexible deployment

Key Features

Hardware RAID for Performance or Protection

• RAID 0 for speed, RAID 1 for redundancy, JBOD for max capacity

• Individual mode allows separate drive access when port multiplier is supported

• No software required and no CPU resources consumed

Note: All data is cleared when switching RAID modes. Backup before configuration

Compatible with Multiple Platforms

• Works with Windows and Linux workstations for gaming, editing, or server use

• QNAP NAS compatibility from QTS 4.4.1 and QuTS hero h4.5.1 onwards

• NAS integration supports SSD caching, Qtier, and tiered storage

• Supports primary boot drive setup on PC (check SATA power specs for compatibility)

Note: USB-to-SATA adapters or SATA ports without 12V power are not compatible

Easy RAID Monitoring with Windows Utility

• Use QNAP External RAID Manager to monitor RAID status and SSD health

• Supports firmware updates via utility

• Enables desktop RAID management without opening the case

Efficient Storage Expansion for QNAP NAS

• Hardware RAID offloads processing from NAS CPU

• Supports SSD tiering or caching to boost IOPS and read/write throughput

• Ideal for SSD volumes in media production, virtualization, or database usage

• QTS detects QDA-A2MAR as a single volume regardless of RAID configuration

Note: QTS does not support Individual mode and Qtier workflows may require multiple SSDs
