Base Model

Streamline storage and speed up workflows with the ThunderBay 4 mini 4-Bay Thunderbolt 3 RAID Array and Drive Enclosure from OWC. Featuring four 2.5" SATA drive bays, this enclosure can hold SSDs or HDDs from different brands and with capacities for easy replacements and upgrades. Two Thunderbolt 3 ports facilitate transfer speeds up to 1556 MB/s, while also allowing you to daisy-chain devices for exponentially faster performance. The ThunderBay 4 mini can be used to hold four independent storage drives. Or, combine all the disks in JBOD mode for faster storage. Select different RAID levels for tailored performance with OWC's SoftRAID utility, available separately.

A 60mm cooling fan keeps thermals low, while a locking bay door and Kensington Lock slot can be used to keep storage secure. Furthermore, the aluminum construction provides resilience for daily use. The OWC ThunderBay 4 mini is compatible with Windows 10 and later, Windows Server 2016 and later, and macOS 10.13 and later. When using independent volumes, this enclosure is bootable in macOS.

Thunderbolt 3

Thunderbolt 3 is a hardware interface that utilizes the reversible USB Type-C connector. Doubling the speed of its predecessor, Thunderbolt 3 features a maximum throughput of 40 Gb/s when used with compatible devices. The connector also transmits data via USB 3.1 at up to 10 Gb/s, and dual-bandwidth DisplayPort 1.2 allows you to connect up to two 4K displays simultaneously. Additionally, you can daisy chain up to six devices from a single Thunderbolt 3 port.

Flexible 4-Bay Design

Sporting four drive bays, this enclosure accepts 2.5" SATA SSDs and HDDs, regardless of capacity or brand. Use mixed drives independently or combine drives into a RAID array with SoftRAID setup and management software, available separately.

Optimize Your Workflow

Expand production capabilities in creative platforms like Final Cut X, Avid Pro Tools, Apple Pro Logic, and Adobe Lightroom. Edit large images, manage massive photo and audio libraries, store drone videos, or use the ThunderBay 4 mini as a transport drive to speed up your post-production process.

Install or Swap in Minutes

Open the front panel security lock to access the four individual bays. Drives mount to a tray that slides back in and automatically plugs into a drive connector so you can get back to work in minutes.

Store More, Go Faster

Daisy-chain up to five additional ThunderBay 4 mini solutions to create massive storage capacities. Or, get even greater flexibility, capacity, and capability by merging multiple units using SoftRAID software, available separately. Or if speed is what you're after, connect multiple ThunderBay 4 mini solutions to multiple Thunderbolt 3 ports on your Mac or Windows computer to achieve exponentially faster performance.

Professional Grade and Ready to Work

Every ThunderBay 4 mini undergoes a multi-step performance certification prior to shipping, ensuring your enclosure arrives ready for demanding use.

SoftRAID Compatible

This enclosure is compatible with OWC SoftRAID. Designed for intuitive use, this software RAID utility provides multiple RAID levels so you can select the RAID level that fits you or your project's needs. Choose your RAID level for maximum volume capacity, optimum drive performance, data protection, or a combination of attributes. Featuring drive validation, verification, and failure prediction, SoftRAID puts the power of a data center on your desktop. From home users looking to protect photos and documents to professionals needing to protect and quickly access projects, SoftRAID ensures streamlined operation of your storage.

Secure Your Workflow with OWC ClingOn

Reduce cable strain and accidental disconnects with the OWC ClingOn. Screwing into the ThunderBay 4 mini's housing to secure your Thunderbolt 3 and USB Type-C connections, these optional cable stabilizers prevent work session interruption and possible data loss.
