OWC ThunderBay Flex 4chat_bubble_outlineFrom real comments

Flexible RAID and PCIe expansion win over prospective buyers. Commenters evaluating the enclosure for 4K video workflows appreciate that it supports selectable RAID levels including RAID 5, letting them balance redundancy and performance for archiving and editing off the drive. Its PCIe slots also draw strong interest, with users asking about adding NVMe modules, OWC's U.2 Shuttle, or Blackmagic and AJA capture cards to extend the system's capabilities beyond plain storage. A couple of owners describe their multi-enclosure setups as 'impressive' or simply call the unit a 'great product,' reflecting genuine enthusiasm from people already running it in professional environments.

Multi-workstation sharing is more limited than buyers expect. Several commenters hoped to connect two computers simultaneously, such as pairing a Mac mini as a NAS with a Mac Studio as direct-attached storage, but OWC support confirmed the enclosure cannot be mapped or shared to a second workstation over a network. This disappointed users planning shared team editing setups where multiple people needed to access footage, project files, and digital assets from the same drive at once, since the design apparently restricts access to a single connected system rather than functioning as true shared network storage.

Compatibility problems surface with T2 chips, backups, and specific drives. One owner reports that software RAID does not work with Apple's T2 chip and that OWC has not resolved the issue, while also criticizing being charged for return shipping. Another user's RAID 5 volume was rejected by Backblaze's cloud backup software with a duplicate-drive error. A third reports their Mac Studio restarts repeatedly when using certain drive combinations, including WD Ultrastar and Seagate IronWolf models, and says the same problem occurs with a related ThunderBay unit.
