## Long description

OWC ThunderBay 4 mini is a compact 4-bay external HDD/SSD enclosure for 2.5" SATA drives that delivers multi-drive storage and hardware RAID options with up to 20 Gbit/s interface throughput. The enclosure supports RAID levels 0, 0+1, 1, 4, 5 and JBOD and is designed for desktop expansion, backup tasks and media workflows that require simultaneous high capacity and throughput. The enclosure housing is black and made to dissipate heat while offering tool-free drive access via a front panel lock and slide-in drive trays.
Advantages
The ThunderBay 4 mini offers a balance of compact size and high-performance capability: four independently swappable 2.5" SATA bays, Thunderbolt connectivity compatible with modern high-speed workflows, and bundled SoftRAID software for flexible RAID creation and monitoring. Its aluminum chassis aids passive cooling and the daisy-chainable Thunderbolt ports allow expansion of storage capacity or aggregated throughput by connecting multiple units. The included SoftRAID XT software provides drive validation, monitoring and cross-platform compatibility for macOS and Windows.
Suitable for
Desktop storage expansion and local backups
Photo, audio and video editing workflows that use multiple drives or RAID arrays
Transport and on-set media ingest when compact, rugged storage is required
Archiving and library storage where redundant RAID protection or high capacity is needed
Key specifications
Drive bays: 4 × 2.5" Serial ATA (SATA) drives
Interface bandwidth: up to 20 Gbit/s (Thunderbolt 2 compatible and backward compatible)
Supported RAID levels: 0, 0+1, 1, 4, 5, JBOD (via SoftRAID/hardware options)
Peak performance examples: up to approximately 750 MB/s for HDD arrays and up to approximately 1346 MB/s for SSD arrays in RAID 0 configurations
Connectivity: daisy-chainable Thunderbolt ports for expansion
Power: external AC adapter with DC output (72 W rated)
Enclosure material and color: heat-dissipating aluminum chassis, black finish
How to use
Install 2.5" SATA HDDs or SSDs into the individual drive trays and slide each tray into the front bays until it seats and connects. Use the front panel security lock to prevent unintended access. Connect the enclosure to a compatible host via Thunderbolt and, if required, chain additional ThunderBay 4 mini units to the host or to each other. Configure desired RAID levels and volume options using the included SoftRAID XT software on macOS or Windows, or use the hardware RAID options provided by the enclosure if applicable.
Usage recommendations
For reliable performance, use drives with similar capacity and performance characteristics when creating RAID arrays. Enable SoftRAID monitoring to receive proactive alerts, validate new volumes before storing critical data, and perform regular backups of essential files. Keep adequate ventilation around the enclosure and avoid placing it on heat-retaining surfaces.
