General Information:

4 SSD + 4 HDD Maximum Flexibility Configuration

Get the best of both worlds: a blazing-fast, high-capacity SSD RAID 0 project drive for large format, multi-stream workflows along with the added long-term storage capacity of an HDD RAID 5. Plus, enjoy docking convenience and expand your capabilities by selecting a recommended PCIe card or add your own.

Flex Your Way Through Every Workflow

Whether you call it a workflow workhorse, a productivity platform, or a configurable command center, one description of the ThunderBay Flex 8 says it best. It is a groundbreaking workflow solution for digital imaging, VFX, video production, and video editing professionals from the world's leading Thunderbolt accessory manufacturer.

ThunderBay Flex 8 offers eight drive bays that support a mix of SATA/SAS and U.2/M.2 NVMe drives for virtually limitless storage capacity. Next, there's a plethora of ports including two Thunderbolt 3, one USB-C, and two USB-A for device docking and charging.

See your work in greater detail by adding up to an 8K display via a built-in DisplayPort 1.4 connection. Ingest hi-res images and video via front-side SD 4.0 and CFexpress card readers. And when you want to expand your desktop capabilities, there's a PCIe slot waiting for your specific project needs.

ThunderBay Flex 8 is the one Thunderbolt 3 desktop device that rules them all. With an irresistible economy of scale, this consolidated solution is ideal for anyone waiting for the right moment to invest in Thunderbolt technology.

NVMe. PCIe. What's It Mean to Me?

At the heart of the ThunderBay Flex 8 capabilities are two cutting-edge technology standards: NVMe and PCIe. Non-Volatile Memory Express (NVMe) optimizes the performance of modern flash technology over the Peripheral Component Interconnect Express (PCIe) standard. It enables significantly faster SSD performance with a more direct and optimized path to a computer's processor.

Tying both of these technologies together is the Thunderbolt 3 interface which uses the PCIe bus. This interface offers the fastest data transfers possible on a single cable between computers and peripherals like storage solutions, docks, and expansion devices while also supplying 85W of power to keep your laptop ready to go at a moment's notice.

Muscle-FLEXing Data Performance

Right out of the packaging, the top four bays are configured with four SSDs while the bottom four bays are configured with high-performance enterprise-class 3.5-inch HDDs. On solutions with four SATA 6Gb/s SSDs, you enjoy broad drive-swappable compatibility with other OWC ThunderBay units. On solutions with four U.2 NVMe SSDs, you are ready for the future storage standard used in content creation and video production. With real-world read/write speeds of 2750MB/s that saturates the Thunderbolt 3 speed threshold, you're ready to handle 4K/8K and even Phantom high-speed files.
