Thunderbolt Made Easy
We make it easy to choose the right gear. Our Thunderbolt Certified products offer the same performance and functionality whether they are Thunderbolt 3 or Thunderbolt 4. And if you’re rocking a beloved Thunderbolt 2 machine, we offer an adapter so you can plug into our universe of award-winning solutions. No hassles, no confusion. That’s the OWC Difference.
Apple Mac models with Thunderbolt 2/Thunderbolt ports can be connected using an Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter and a Thunderbolt 2 cable (available separately). This configuration provides data transfer at up to 20Gb/s but does not support notebook charging.
RAID Made Easy
Harness the full capability of your OWC drive array with the included SoftRAID XT, the most powerful, intuitive RAID management software on the market for macOS and Windows. SoftRAID’s RAID creation and management technology has been finely tuned to perfection with over 20 years of development to provide rock solid protection of your data and optimize drive performance.
Packed with Features
SoftRAID XT provides an unbeatable combination of speed, protection, and compatibility:

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 »
- RAID 4/1+0 (10) is available for Mac only at this time.
- SoftRAID serial numbers work on both Mac and Windows. SoftRAID is licensed per computer. In order to use SoftRAID on multiple computers, you will need a unique, valid license per computer. Additional licenses can be purchased anytime.
Ready to Rack
Flex 1U4 comes complete with hardware for mounting into most racks and cabinets.
OWC Thunderbolt Cable Included
OWC Flex 1U4 comes with a certified 0.7M OWC Thunderbolt Cable. But if your workflow demands a different length to make the connection, OWC Thunderbolt (USB-C) Cables are the perfect choice.
Certified for Demanding Use
We understand having confidence in gear reliability is paramount to creative professionals. That’s why OWC Flex 1U4 solutions go through a multi-step performance certification prior to shipping. This ensures they arrive operating properly and immediately ready for demanding use.
Stabilize Thunderbolt and USB-C Cables
Active workspaces expose gear to bumps, shoves, or even the random tail wag from a pet. OWC ClingOn custom cable stabilizers (sold separately) screw into the OWC Dock or OWC Drive housing to reduce – if not completely eliminate – cable strain on Thunderbolt and USB-C connections so you can work with confidence even in the highest foot traffic environments.
OWC, Trusted by Pros & Enthusiasts the World Over
We build our hardware to the highest standards of reliability and performance. Because 100% reliability is always the goal, we rigorously quality test and back our hardware with a 5 Year OWC Limited Warranty and award-winning customer support.
