The QDA-A2MAR can accommodate two M.2 SATA SSDs within a single 2.5-inch SATA drive bay. No software driver is
required for the QDA-A2MAR, and it can be installed in a PC/workstation (Windows®, Linux®) or QNAP NAS to flexibly
add high-performance M.2 SATA SSDs with RAID configurations to meet various storage needs.
Specifications
Use two M.2 2280 SATA SSDs in a single 2.5-inch drive bay. (M.2 SSDs sold
separately)
Up to 6 Gb/s file transfer speeds.
Can be the primary bootable device for PCs.
Switchable Hardware RAID Group Modes.
Features
Supports various RAID levels
The QDA-A2MAR supports a variety of RAID configurations. Depending on your requirements,
you can use the bundled metal pin as disk mode switch tool to select your ideal RAID mode: Individual, JBOD, RAID 0,
or RAID 1. Windows® users can use the QNAP External RAID Manager utility to view the RAID group status and disk
health information.
Install in a PC/workstation for higher performance or data
protection
When using two M.2 SSDs instead of a single 2.5-inch drive in a PC/workstation (Windows®
or Linux®) you can create a RAID 0 for enhanced performance, or RAID 1 to add data redundancy for greater data
protection. The M.2 SSDs also help achieve maximized performance and lower latency, ideal for on-the-fly video
editing and server-grade applications.
External RAID Manager for Windows users
The QNAP External RAID Manager utility allows Windows® users to view the drive status
and RAID information of the QDA-A2MAR. Firmware updates for the QDA-A2MAR can also be managed with the External RAID
Manager utility.
Install in QNAP NAS for efficient storage or SSD caching
The QDA-A2MAR supports hardware RAID that will not consume CPU resources to help sustain
optimal NAS performance. You can install one or more QDA-A2MAR in a NAS to maximize the storage utilization of
available 2.5-inch drive bays.
The QDA-A2MAR can accommodate two M.2 SSDs to create an SSD volume for performance-demanding workflows or work in an
efficient tiered-storage environment with Qtier. It can also boost IOPS performance when configuring SSD caching.
RAID information and disk health of the QDA-A2MAR can be monitored through the QTS Storage & Snapshots Manager.

The QDA-U2MP can accommodate two M.2 PCIe 3.0 x4 NVMe SSDs within a 2.5-inch U.2 (SFF-8639) PCIe 3.0 x4 NVMe SSD drive bay. No software driver is required for the QDA-U2MP, and it can be installed in a PC/workstation (Windows®, Linux®) or QNAP NAS to replace an expensive U.2 SSD with more-affordable M.2 SSDs.
Specifications
Install two M.2 2280 (M key) PCIe NVMe SSDs in a U.2 PCIe NVMe SSD drive bay (M.2 SSDs sold separately).
Up to PCIe 3.0 x4 file transfer speeds.
Features
High-quality construction for better heat dissipation/p>
The M.2 SSD thermal pads and aluminum-alloy metal frame assist in dissipating heat from the M.2 SSD to ensure high performance.
Install in a PC/workstation for higher performance or data
protection
Use the QDA-U2MP to install two M.2 SSDs in the 2.5-inch U.2 SSD tray of a high-end PC/workstation (Windows® or Linux®), and easily deal with tasks that require intensive data transmission (such as on-the-fly video editing, server-grade applications, or online gaming).
