The Rackmount Workflow Game-Changer
Since the launch of the OWC ThunderBay desktop storage line in 2014, computer users across the planet have continued to fall in love with it. They embrace its massively powerful RAID capacity and intense performance fueled by time-tested OWC reliability. Its appeal skyrocketed when it was infused with industry-first FLEXibility to create ThunderBay Flex 8.
Now businesses, institutions, studios, and creatives can go beyond the desktop with the OWC Flex 1U4. This innovative 4-bay rackmount solution is ready to fuel your endeavors with the best combination of storage capacity, Thunderbolt transfer performance, drive flexibility, and device expandability. With FLEX in its name, you can count on Flex 1U4 to be your rackmount workflow game-changer.
