Professional Grade 4-Bay Thunderbolt 3 Storage Solution
Transform your workflow with the OWC ThunderBay 4 mini, the perfect combination of professional-grade speed, compact size, and ultimate convenience. Designed for creative professionals, DITs, and power users, this 4-bay enclosure turns your 2.5-inch SSDs or HDDs into a high-performance Thunderbolt 3 storage powerhouse. Despite being about the length of a pencil and weighing just over three pounds, the ThunderBay 4 mini delivers the performance of a massive RAID system, achieving blistering speeds of up to 1556MB/s. This gives you more than enough bandwidth to handle everything from daily backups to the most demanding high-resolution audio, photo, and video formats.
Experience a new world of flexibility. The four universal 2.5-inch drive bays allow you to mix and match different brands and capacities of SSDs and HDDs. Use drives independently or combine them into a powerful RAID array using the included SoftRAID software. SoftRAID makes setup effortless, guiding you to create the perfect balance of speed and redundancy for your specific needs, whether it's RAID 0 for maximum performance or RAID 5 for data protection. The drives are mounted on hot-swappable trays, allowing you to access or expand your storage in minutes without tools.
Expand your capabilities far beyond storage. With two Thunderbolt 3 ports, you can daisy-chain up to five additional Thunderbolt devices, including more ThunderBay units for massive capacity, 5K or dual 4K displays, and other essential peripherals. Engineered with a rugged, heat-dissipating aluminum chassis and a whisper-quiet cooling fan, the ThunderBay 4 mini is built for demanding environments. Each pre-configured solution undergoes a rigorous multi-hour burn-in process, ensuring it's deployment-ready right out of the box. Backed by OWC's commitment to quality and a robust warranty, it's the reliable, high-speed storage solution your workflow demands.

If you would like to return any item(s), please contact us by either emailing info@dittools.eu or calling (+372) 5556 0057.

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.
