The QNAP QDA-UMP4 in depth

Cost-effective NVMe in U.2 bays

The QDA-UMP4 lets you use M.2 NVMe SSDs as an alternative to U.2 NVMe SSDs, optimising data-intensive applications at a lower cost and boosting IOPS when used for SSD caching. QNAP tested it in a TDS-h2489FU running QuTS hero h5.0 with a Seagate IronWolf 525 M.2 NVMe SSD.

Using it with Qtier

With Qtier on an HDD pool that uses RAID 1, 5 or 10, QNAP requires two SSDs in the SSD tier, such as two QDA-UMP4 or one SSD plus one QDA-UMP4. To replace a drive in the adapter, disable Qtier first so its data moves to the NAS storage pool.
