  • Breathtaking Thunderbolt 2 performance with sustained speeds of up to 1,284MB/s
  • RAID-ready with up to 4TB of SSD storage (HDD up to 8TB)
  • Near-silent operation
  • SoftRAID 5 - first ever software RAID 5 for the Mac (available with ThunderBay 4 mini RAID 5 Edition)
  • Flexibility to combine multiple ThunderBays into a single massive RAID array
  • Regimented multi-hour drive "burn-in" for ultimate reliability

Thinking Outside the Enclosure
OWC unlocks the incredible performance and flexibility of ThunderBay by pairing the drives with a robust software RAID solution. Powered by the SoftRAID engine, ThunderBay 4 mini RAID 5 Edition delivers advanced RAID modes, real-time health monitoring with email notifications, and best-in-class rebuild speeds. Unlike traditional software RAID solutions, SoftRAID's revolutionary volume optimization allows you to quickly configure your drive for specific workflows. Now you can experience the absolute best performance whether recording audio, editing 4K video, or creating a multimedia server.

"Our new ThunderBay 4 mini is perfect for mobile workflows involving demanding applications and large mission-critical files," said Jen Soulé, OWC President. "The combination of RAID-ready capabilities and Thunderbolt 2 technology makes working with large 2K and 4K files easier, faster, and more flexible and affordable than ever before. Now users can get big performance in a small footprint - all in a portable, production-grade 4-Bay enclosure."

The RAID 5 Advantage
Thunderbay 4 mini RAID 5 Edition is preconfigured in RAID 5 and supports RAID 0, 1, 4, 5, and 1+0 enabling you to achieve the optimal balance of storage, performance, and data-redundancy your workflow demands. With RAID 5, the four drives inside ThunderBay 4 mini are merged for increased capacity and tremendous performance gains over a single drive. Special redundancy data, called "parity information," is also stored across the drives, allowing your data to remain completely safe so you can maintain your mission-critical workflows worry-free.

Each ThunderBay 4 mini undergoes OWC's regimented multi-hour drive "burn-in" to ensure you experience the amazing performance of your drive right out of the box.
