Product information

Description

ICY BOX IB-RD3720-CU3 is a 2-bay HDD/SSD enclosure that supports both 2.5" and 3.5" SATA drives and provides flexible RAID operation via an integrated DIP switch. The unit accepts two SATA II/III drives and supports RAID 0, RAID 1, SINGLE and LARGE modes. With a USB 3.2 Gen 1 Type-C connection delivering up to 5 Gbit/s and an integrated 50 x 50 mm fan for active cooling, the enclosure is designed for stable transfer of large files and continuous operation. The compact black housing includes the necessary power adapter and interface cables for immediate use.

Advantages

The enclosure combines dual-bay RAID capability with hot-swap support, letting you change drives without powering down the system. A user-accessible DIP switch simplifies switching between performance-oriented and redundancy-oriented modes without additional software. Active cooling maintains safe operating temperatures under sustained workloads, and the USB Type-C interface ensures broad compatibility and up to 5 Gbit/s data throughput for fast file transfers.

Suitable for

  • Local backup and mirror storage for small office or home office
  • Storage and editing of large media files, such as video and photo libraries
  • Data consolidation and transport between systems using USB-C
  • Temporary expansion of desktop or notebook storage via external drives

Key specifications

  • Supported drive types: 2.5" and 3.5" SATA HDD or SSD
  • Number of drive bays: 2 (dual-bay)
  • Supported SATA standards: SATA II and SATA III
  • Maximum combined capacity (per manufacturer guidance): up to 60 TB with two large-capacity drives
  • RAID modes: RAID 0, RAID 1, SINGLE, LARGE (configurable via DIP switch)
  • Data interface: USB 3.2 Gen 1 Type-C (up to 5 Gbit/s)
  • Hot-swap support: yes
  • Cooling: 50 x 50 mm fan
  • Power: external DC power adapter included
  • Colour: black

How to use

Install one or two 2.5" or 3.5" SATA drives into the bays following the mechanical guides, connect the external DC power adapter and plug the USB Type-C cable into your host device. Select the desired RAID mode using the integrated DIP switch: choose RAID 0 for increased performance, RAID 1 for mirroring and redundancy, SINGLE for individual drives, or LARGE to combine capacities into a single volume. The unit supports hot-swap operations, allowing drive replacement while powered when the host and operating system support it.

Usage recommendations

For reliable operation, use drives of the same capacity and similar performance characteristics when configuring RAID 0 or RAID 1. Ensure adequate ventilation around the enclosure to allow the fan to maintain optimal temperatures, and perform regular backups even when using redundant RAID modes. Use a USB 3.2 Gen 1 Type-C port on the host for full transfer speeds and confirm your operating system recognises external RAID configurations before deploying critical data.

Use caseRecommended productWhy
Dual-drive local storage with data protection or stripingICY BOX IB-RD3720-CU3Supports two 2.5 or 3.5-inch drives with hardware RAID 0/1 and hot-swap capabilities for reliable desktop storage.
Enterprise-grade massive server storage expansionSynology RX1223RPAccommodates up to 12 drives, making it heavily over-provisioned for personal use but essential for rackmount business servers.
Four-drive workstation setup without hardware RAIDICY BOX IB-3740-C31Provides four drive bays with faster 10 Gbit/s USB-C connectivity for users needing more capacity than a two-bay unit allows.
Portable single-drive file transportICY BOX IB-AC703-C or IB-273StU3Compact single-bay designs built exclusively for one 2.5-inch drive, ideal for mobile use rather than stationary desktop setups.
The primary difference between the ICY BOX IB-RD3720-CU3 and the alternatives is its balanced two-bay design with hardware RAID 0 and 1 support, offering up to 30 TB of capacity via USB Type-C. This product is most suitable for home and office users who need a dedicated desktop storage solution with the option for data redundancy or performance striping using two drives. A buyer should prefer this model over single-bay enclosures when a single disk is no longer sufficient, while avoiding the excessive size and complexity of large multi-bay units.
