QNAP AC QDA-UMP4 M.2 2280 PCIe NVMe Gen4x4 t U.2 PCIe NVMe converter adapter

The QDA-UMP4 allows installing an M.2 PCIe 4.0 x4 NVMe SSD in a 2.5-inch U.2 (SFF-8639) PCIe 4.0 x4 NVMe SSD drive bay. No extra software or drivers are required for the QDA-UMP4 and it can be installed in a PC/workstation (Windows®, Linux®) or QNAP NAS to enable using M.2 SSDs as cost-effective alternatives to expensive U.2 SSDs.


1. Use an M.2 2280 (M key) PCIe NVMe SSD in a U.2 PCIe NVMe SSD drive bay (M.2 SSD sold separately).

2. Up to PCIe 4.0 x4 file transfer speeds.

(Compatible with NVMe PCIe 3.0 for M.2 SSDs and U.2 drive bays)


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

By using the QDA-UMP4 to install a M.2 SSD in the 2.5-inch U.2 SSD tray of a high-end PC/workstation (Windows® or Linux®), you can obtain a more budget-friendly way to supercharge bandwidth-demanding applications (such as on-the-fly video editing, server-grade applications, or online gaming). The status of the installed SSDs can be monitored using your preferred monitoring tool (such as manufacturer-provided utilities or third-party software like CrystalDiskInfo).

Note: Consult your PC system provider regarding compatibility with U.2 NVMe SSD.
