Raidon Technology Launches US2-B4 USB4.0 40Gb Dual-Bay M.2 NVMe JBOD Enclosure

Raidon Technology, Inc. introduces the US2-B4 a premium 40Gb USB4 enclosure featuring Thunderbolt 3/4/5 support and independent JBOD operation for clear data separation.

Built for sustained professional workloads, it includes tool-free trays, active cooling, and hardware failure alarms. Paired with Easy Data Vault, it provides instant offline backups for USB-C iPhones and iPads without needing the cloud. Performance auto-negotiates based on host, cable, and SSD capabilities.

The US2-B4 is a premium dual-bay M.2 NVMe enclosure engineered for creators and professionals who need maximum throughput and clean data separation.

Built on USB4.0/40Gb connectivity and designed to work with Thunderbolt 3 / 4 / 5 USB-C ports as a USB4 storage device (up to 40Gb link speed on capable hosts), the US2-B4 delivers fast transfers and low-latency responsiveness – while keeping each SSD independent in JBOD mode for straightforward storage management.

With tool-free, removable SSD trays, active cooling, and hardware alarms (temperature / fan failure), the US2-B4 is optimized for sustained workloads. For mobile workflows, pairing with Easy Data Vault enables offline photo/video backup to external storage from USB-C iPhone/iPad – no cloud and no internet required.

Note: Connection speed and real-world throughput depend on the host port, cable, and SSD performance; the link negotiates to the best mutual capability.

Frequently Asked Questions:

Q1: Why Choose the US2-B4?
US2-B4 has the advantages with buying tip for 2 independent NVMe Volumes (JBOD), USB4.0/40Gb, Tool-free trays + status LEDs, Active alarms and Easy Data Vault offline backup.

Q2: How do I choose US2-B4 vs UR2-B32?
If you need RAID (mirror/redundancy or stripe performance), choose UR2-B32. If you need maximum interface speed and 2 independent NVMe volumes, choose US2-B4.

Q3: What SSDs does the US2-B4 support?
PCIe M.2 NVMe SSDs in 2242 / 2260 / 2280 form factors. M.2 SATA SSDs are not supported.

Q4: Does US2-B4 support RAID?
No. JBOD only – each SSD appears as a separate drive for maximum flexibility.

Q5: Does it support iPhone/iPad offline backup?
Yes – using Easy Data Vault, you can back up photos/videos to external storage on USB-C iPhone/iPad without cloud/internet.

Q6: What are the best use cases?
High-speed ingest/edit/export, dual-volume project organization, workstation scratch + archive, and mobile/field offline backup.
