OWC ThunderBay 4 with Thunderbolt 2 in Photography Workstation

Certified and Tested

Each ThunderBay undergoes OWC's multi-hour drive "burn-in" performance certification procedure prior to shipping. This ensures your ThunderBay arrives operating properly and ready for demanding use.

Time-Tested Cooling

Built on OWC's time-tested enclosure cooling technology, ThunderBay utilizes an open "flow-thru" vented design with an oversized 92 mm, low-turbulence, noise-quieting fan to keep the drives running cool and reliably.

Multi-Drive

Daisy-chain up to six ThunderBays for massive storage capabilities and increased performance, or connect multiple ThunderBays to multiple Thunderbolt 2 ports to achieve exponential speed capabilities.

Vibration Dampened

ThunderBay's drive isolating design reduces sonic resonance, and is aided by over-sized, rugged, vibration-absorbing, non-skid feet.

DisplayPort 1.2 Support

Dual Thunderbolt ports let you connect the display of your choice that your computer can support, including 4K displays.

RAID Made Easy

Packed with Features

SoftRAID XT provides an unbeatable combination of speed, protection, and compatibility:

  • Advanced: Create RAID 0/1/4/5/1+0 (10) arrays1
  • Protected: SoftRAID Monitor constantly watches your disks and alerts you if problems are detected
  • Validated: Volume validation ensures sectors can be read and parity is correct
  • Certified: Checks disks before use to ensure they are safe for data storage

Beyond Hardware RAID

SoftRAID provides a level of storage performance that you simply can’t get with hardware RAID. Software RAID gives you increased power and control over your RAID drives and disks that hardware RAID can’t deliver and doesn’t lock you into technology that you can’t upgrade or expand.

Dive deeper into the benefits of SoftRAID »
