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/SAS1 and U.2/M.22 NVMe drives for virtually limitless storage capacity. Next, there’s a plethora of ports including two Thunderbolt 33, one USB-C, and two USB-A for device docking and charging.

See your work in greater detail by adding up to an 8K display4 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.

Done with the drives but need the docking connectivity?

Eject the ThunderBay Flex 8 drives and any external drives in a single click with the free OWC Dock Ejector app. It ensures all data has been written before any drive is unmounted to protect against data loss. It will even warn you from accidentally ejecting an in-use drive.

Docking FLEXibility

A virtual buffet of productivity-enhancing possibilities awaits you with the docking connections built into ThunderBay Flex 8. Power your notebook with up to 85W power delivery while capturing multi-stream hi-res footage at full frame rate. Connect audio and video mixers, digital camera, keyboards, and other peripherals and charge mobile devices via one USB-C and two USB-A 10Gb/s ports. Ingest and work with 4/8K RAW video and RAW photo files immediately at speeds up to 985MB/s with frontside SD 4.0 and CFexpress card readers. Add more viewing space with up to an 8K monitor via the DisplayPort 1.4 interface. And if all that’s not enough to satisfy your project needs, daisy-chain up to five additional Thunderbolt 3 devices!

FLEXpandable for Unique Needs

By removing the enclosure’s side panel, you can expand your capabilities by installing a half-length, full-height, single-width expansion card in the PCIe x16 connector/x4 lanes slot. Add a 4K video capture card for direct ingest of multi-stream high-res footage. Record high-quality tracks with an audio card and then edit and archive tracks.

Create a powerful file server with a high-speed networking card. By replacing the built-in SATA drive controller with a SATA or SAS RAID card, you can turn ThunderBay Flex 8 into a hardware RAID storage solution while keeping a PCIe slot open for other cards.

Includes SoftRAID XT: Easy and Complete Drive Management

SoftRAID XT is the most powerful, intuitive software RAID utility on the market. Multiple RAID options let you select the RAID level that fits you or your project’s needs best.

SoftRAID provides a level of performance that you simply can’t get with hardware RAID. Learn more about the power of SoftRAID XT.

A Protective, Economical Post-Production Solution

Sending a drive from set to post-production typically entails tedious and time-consuming drive enclosure disassembly to access the storage drive or costly shipping of the entire enclosure to the post lab. But ThunderBay Flex 8 offers yet another option.

By installing an OWC U.2 NVMe Interchange System carrier tray (sold separately) with a built-in U.2 connector into a ThunderBay Flex 8 drive tray, you can protect the U.2 SSD drive’s connector from repeated install/removal wear for improved drive longevity and investment. When done with your shoot, just ship the lightweight protective carrier and drive to the lab where the carrier can be installed into an OWC Helios 3S equipped with the OWC Interchange System. It’s a complete solution to safeguard your data while lowering shipping costs.
