Raidon Technology Introduces UBOX Micro M.2 NVMe to 2.5-Inch U.2 NVMe High-Performance Adapter
Compliant with U.2 (SFF-8639) specifications and support PCIe x 4 NVMe, transforms standard M.2 2280 NVMe SSD (22x80mm) into 7mm-thick 2.5” U.2 NVMe SSD
This is a Press Release edited by StorageNewsletter.com on October 8, 2025 at 2:00 pmRaidon Technology, Inc. announces the Stardom UBOX Micro, a M.2 NVMe SSD to 2.5″ U.2 NVMe SSD (7mm) performance adapter.
UBOX Micro is a compact and high-performance adapter that transforms a standard M.2 2280 NVMe SSD (22×80 mm) into a 7mm-thick, 2.5″ U.2 NVMe SSD. It provides a flexible and durable upgrade solution for servers, workstations, and embedded or industrial systems that rely on U.2 bays and backplanes. Compliant with U.2 (SFF-8639) specifications and support PCIe x 4 NVMe, UBOX Micro makes you easy to install fast M.2 storage in hot-swap systems of U.2.
- Ultra-Thin 7mm Design
Converts an M.2 2280 NVMe SSD into a standard 2.5″ U.2 NVMe SSD (7mm z-height) and ideal for compact systems and dense storage bays. - Optimized for 2280 NVMe
Secure and stable mounting for standard M.2 2280 (22×80 mm) NVMe drives. - Service-Friendly Upgrades
Swap M.2 NVMe SSDs using existing U.2 trays, backplanes, or mobile racks, and no new hardware required. - Standards-Based U.2 Interface (SFF-8639)
Matches U.2 size, port placement, and electrical specifications for plug-and-play integration with U.2 systems
- High-Speed Performance (Up to 40Gb)
NVMe over PCIe delivers fast speeds with low delay. U.2 supports up to 4 PCIe lanes for high-performance use. Actual speed depends on the PCIe version and setup of your system. - Metal Enclosure with Passive Cooling
Durable housing protects the SSD in harsh or vibration environments and improves heat transfer to reduce slowdowns during the heavy use
- Integrated Thermal Management
Installed thermal pads help to transfer heat away from the SSD controller and NAND chips, so the drive can keep running at fast speed during heavy use
Benefits:
- Plug-and-Play U.2 Support
Works with standard U.2 bays for easy hot-swap and maintenance – perfect for scaling. - Consistent High Performance
Metal chassis and thermal pads prevent overheating, ensuring stable speeds during heavy use. - Durable, Easy-to-Handle Design
Protects M.2 SSDs in a rugged 2.5″ form – ideal for labeling, tracking, and quick replacements. - Cost-Efficient Upgrades
Use existing U.2 infrastructure with M.2 SSDs to save money and expand hardware options. - Possible Applications: Enterprise and Cloud Servers
Using NVMe as boot drives, cache, or hot-swap storage with existing U.2 setups - Pro Workstations
Ideal for 8K video, VFX, or CAD work with easy to service U.2 drives - AI/ML and HPC Systems
Fast and reliable storage for datasets, feature stores, and model checkpoints - Edge and Industrial PCs
Rugged 2.5″ storage for factories, transport, and telecom environments - Labs and Homelabs
