Want Even More Storage?

To keep your workflow on the cutting edge, we’ve included an additional slot for an M.2 NVMe SSD to help future-proof your storage needs. Use it for additional storage or as a scratch disk.

The Better and Simpler Way to RAID

ThunderBay 6 manages and protects your data with OWC's advanced SoftRAID engine.  With multiple RAID options (0, 1, 4, 5, 1+0 (10)), you can set it up for speed, data security or the best of both worlds.


Packed with features from active predictive disk failure monitoring to multiple array volume spanning, SoftRAID from OWC brings technology typically found only in data centers to your workstation or editing bay. It constantly monitors your disks, alerting you when a disk is becoming unreliable and is likely to fail. Replacing a disk before it fails saves you precious uptime.

Storage Pools

ThunderBay 6, coupled with Windows Storage Spaces (available in Windows 10), allows you to create storage pools and simple, mirror or parity spaces based on the mix of data protection and performance you need. If you run low on capacity, just add more ThunderBay units to the storage pool.

Expand and connect as needed

Link up to 6 Thunderbolt units together with Thunderbolt’s daisy chaining capabilities. Combined with our SoftRAID technology, you can configure a storage solution tailored to your unique workflow. SoftRAID can create volumes that span multiple arrays or generate a nested RAID configuration for even greater performance and protection.
