Professional Speed, Compact Power: Your Customizable Thunderbolt 3 Storage Hub
Unlock the full potential of your 2.5-inch drives with the OWC ThunderBay 4 mini. Designed for creative professionals and power users, this compact yet powerful 4-bay enclosure transforms your SSDs and HDDs into a professional-grade Thunderbolt 3 storage solution. Experience the perfect blend of speed, size, and convenience for your demanding workflows, from on-set DIT carts to your editing suite desk.
Don't let its small footprint—about the length of a pencil—fool you. The ThunderBay 4 mini is a performance heavyweight. With dual Thunderbolt 3 ports delivering blistering speeds up to 1556MB/s, you have more than enough bandwidth to edit high-resolution video, manage massive photo libraries, and run complex audio sessions directly from the drive. The rugged, heat-dissipating aluminum enclosure and whisper-quiet fan ensure your drives stay cool and reliable during even the most intensive tasks.
Flexibility is at the core of the ThunderBay 4 mini. Bring your own 2.5-inch SSDs or HDDs, mixing and matching brands and capacities to suit your exact needs. The included SoftRAID software makes creating and managing advanced RAID volumes effortless. Configure for maximum speed (RAID 0), critical data protection (RAID 1), or a balance of both (RAID 5, 1+0). When your project grows, simply daisy-chain up to five additional Thunderbolt devices, including more storage or even a 5K display, through the second Thunderbolt 3 port. With hot-swappable drive trays and plug-and-play simplicity for both Mac and Windows, the ThunderBay 4 mini is the ultimate, deployment-ready hub for your digital life.

Customs, duties & taxes
There are no customs duties or taxes on orders shipping within the EU. Orders shipped outside of the EU may be subject to import taxes, customs duties and fees collected by the destination country. The recipient of an international shipment may be subject to such import taxes, customs duties and fees, which are collected once a shipment reaches the recipient's country. Additional charges for customs clearance must be paid for by the recipient; we have no control over these charges and cannot predict what they may be. Customs policies vary widely from country to country; and when customs clearance procedures are required, it can cause delays beyond our original delivery estimates. We advise that you contact your local customs office for more information.
