QDA-UMP specification sheet

Overview:

QDA-UMP
Use an M.2 PCIe NVMe SSD in a U.2 PCIe NVMe SSD drive bay for PC and NAS

Features:

he QDA-UMP can accommodate an M.2 PCIe 3.0 x4 NVMe SSD 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-UMP, and it can be installed in a PC/workstation (Windows, Linux) or QNAP NAS to replace an expensive U.2 SSD with a more-affordable M.2 SSD.

• Use an M.2 2280 (M key) PCIe NVMe SSD in a U.2 PCIe NVMe SSD drive bay (M.2 SSD sold separately).
• Up to PCIe 3.0 x4 file transfer speeds.

Architecture diagram - High-quality construction for better heat dissipation
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 with lower costs
Use the QDA-UMP to install a M.2 SSD 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). Users can use utilities from their SSD manufacturer or third-party providers (for example: CrystalDiskInfo) to view the health status of the installed SSD.

Note: Consult your PC system provider if the PC operating system supports U.2 NVMe SSD.

Maintain high performance with cost savings
Use the QDA-UMP to replace U.2 NVMe SSD with M.2 NVMe SSD and maintain high-level performance.

Install in QNAP NAS for efficient yet cost-effective storage
Install one or more QDA-UMP in a NAS to maximize PCIe bandwidth utilization in a cost-effective way by using M.2 SSD instead of expensive U.2 SSD for optimizing data-intensive applications. It can also boost IOPS performance when configuring SSD caching. Users can monitor drive health and manage SSD usage from the QTS Storage & Snapshots Manager.

Note:
1. QTS 4.4.1 / QuTS hero h4.5.1 (or later) is required for the QNAP NAS.
2. QTS / QuTS hero identifies a QDA-UMP as a single volume (no matter one or two drives installed).
3. When using Qtier in QTS with HDD storage pool in RAID protection (such as RAID 1/5/10 ), then two SSDs are required in the SSD pool (for example, two QDA-UMP, or one SSD plus one QDA-UMP)
4. If a QDA-UMP drive fails and needs replaced: you must disable Qtier to make the QDA-UMP drive data move to the NAS-based storage pool, and then replace the failed QDA-UMP drive.
