Big RAID System Performance in a Compact Design

With four 2.5-inch drive bays, ThunderBay 4 mini transforms SSDs and HDDs into a pro-grade, Thunderbolt 2 storage solution in a compact design. ThunderBay 4 mini is about the length of a pencil and weighs only 3.1 pounds — with SSDs.

The rugged heat-dissipating aluminum enclosure features two Thunderbolt 2 ports (Thunderbolt 10Gb/s backward compatible) for up to 1346MB/s speeds, so you can breeze through personal and business backups all the way up to today's highest resolution audio, photo and video formats.

Use mixed drives independently or combine drives as a RAID with the included SoftRAID setup and management software. Add your own drives or choose from pre-configured solutions that are multi-hour "burn-in" test certified.

Thunderbolt Made Easy

Have a newer Thunderbolt (USB-C) equipped Mac or iPad? Good news – the OWC ThunderBay 4 mini with Thunderbolt 2 is compatible with your device! You'll need a certified Thunderbolt 3 (USB-C) to Thunderbolt 2 (mDP) Adapter and a Thunderbolt 2 cable. The adapter is bi-directional – meaning it can connect a Thunderbolt (USB-C) device to a Thunderbolt 2 Mac and connect a Thunderbolt 2 device (like the OWC ThunderBay 4 mini) to your Thunderbolt (USB-C) Mac or iPad. This compatibility makes it easy to share a OWC ThunderBay 4 mini with both older Thunderbolt/Thunderbolt 2 Mac models and the newest Thunderbolt (USB-C) computers and devices. That's Thunderbolt made easy!

Connect the adapter to one of the available Thunderbolt (USB-C) ports on your Thunderbolt (USB-C) Mac or iPad, then use the Thunderbolt 2 Cable between the adapter and the OWC ThunderBay 4 mini. If you need a Thunderbolt 2 cable to complete your workflow, OWC offers a selection of premium Thunderbolt 2 cables.
