Introduction

This document is by no means an exhaustive list. Most SATA HDDs should be compatible, given that they fit in their respective trays: 2.5" for the Cloud Key Gen2 Plus, 2.5" or 3.5" for the UDM-Pro.

It is strongly advised to choose a hard drive model designed for continuous load, often marketed as NAS or Surveillance Grade drives.  

If you have questions about a particular drive, please search for the drive model on our Community to find other users’ past experiences or start a new related thread if none are found. Please note that support will not be able to provide further recommendations or options beyond referring to this list.

These tables may be expanded in the future as more drives are tested.  Drives are sorted alphabetically by model number.
