Professional Grade Thunderbolt 3 RAID Storage, Compact Powerhouse
Unlock elite-level performance in a remarkably compact form with the OWC ThunderBay 4 mini. Designed for creative professionals, DITs, and power users, this 4-bay enclosure transforms your 2.5-inch SSDs or HDDs into a powerful, pro-grade Thunderbolt 3 storage solution. Whether you're on set, in the studio, or at your desk, the ThunderBay 4 mini delivers the perfect combination of speed, size, and convenience for permanent, reliable access to your most critical data.
Despite being about the length of a pencil, the ThunderBay 4 mini is a performance heavyweight. Its rugged, heat-dissipating aluminum enclosure houses two Thunderbolt 3 ports, capable of delivering real-world speeds up to 1556MB/s. This gives you more than enough bandwidth to handle everything from personal backups to the most demanding 8K video, high-resolution photo, and multi-track audio workflows. The whisper-quiet cooling fan ensures your workspace remains undisturbed while your drives stay cool under pressure.
Flexibility is at the core of the ThunderBay 4 mini. Bring your own drives or choose a pre-configured OWC solution. Mix and match brands and capacities to suit your needs. With the included SoftRAID software, setting up a powerful RAID array is incredibly simple. Choose RAID 0 for maximum speed, RAID 1 for mirrored protection, or more advanced configurations like RAID 4, 5, or 10. The software guides you through every step, while also monitoring drive health to protect you from unexpected failures. Expand your workspace by daisy-chaining up to five additional Thunderbolt devices, including 5K or dual 4K displays, creating a truly versatile and powerful production hub.

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.
