QNAP U.2 Nvme To M.2 Nvme SSD Pcie Adapter H : 7MM - QDA-UMP4A

QNAP QDA-UMP4A U.2 NVMe to M.2 NVMe PCIe SSD Adapter

Overview

The QDA-UMP4A is a passive adapter that lets you install an M.2 NVMe SSD into a U.2 NVMe drive bay on compatible QNAP NAS systems. If you have spare M.2 NVMe drives and open U.2 slots, this adapter bridges the interface gap without requiring a separate enclosure or PCIe card. The 7mm height profile keeps the installed assembly within standard U.2 bay clearance, avoiding mechanical conflicts in dense chassis configurations.

Compatibility

Designed for use with QNAP NAS enclosures and rackmount systems that provide U.2 NVMe bays and expose PCIe Gen 3 or Gen 4 lanes to those slots. Verify your specific chassis supports U.2 NVMe (not U.2 SATA) before ordering — U.2 bays are physically identical but electrically distinct, and a SATA-wired U.2 slot will not work with this adapter. Consult your NAS model's hardware compatibility list to confirm U.2 NVMe bay support before pairing with the QDA-UMP4A.
