The OWC 32TB Thunderbolt 3 Storage Array 4-Bay Flex 1U4from OWC 32TB Thunderbolt 3 Storage Array 4-Bay Flex 1U4is a flexible storage, docking, and PCIe expansion solution for rackmount use. Compatible with macOS 10.15, 11.x, and 12.x, the Flex 1U4 features a storage capacity of 32TB, which is split between three 8TB 7200 rpm SATA 3.5" hard drives and an 8TB NVMe M.2 SSD, with the SSD being housed in an OWC U2 ShuttleOne, which is a 2.5" U.2 NVMe enclosure. Connectivity to your host system is established using a 40 Gb/s Thunderbolt 3 port, which supports data transfers of up to 5000 MB/s. Daisy-chain five additional devices or add a second display to a second Thunderbolt 3 port, while two 10 Gb/s USB-C ports, three 10 Gb/s USB-A ports, and one DisplayPort 1.4 port provide additional connectivity options. Further expansion methods, such as audio/video capture cards, 10Gb Ethernet, SSD storage, a hardware RAID, or other I/O card, can be used via the PCIe 3.0 x16/x4 slot.

If you'd like to upgrade or replace the storage in your Flex 1U4, the drive bays natively support 2.5" and 3.5" SATA drives, as well as 2.5" and 3.5" U.2 drives. SAS drives are supported with an SAS drive controller (sold separately) and M.2 drives are supported using an M.2 to U.2 adapter, such as the OWC U2 Shuttle and OWC U2 ShuttleOne (sold separately). Also, the Flex 1U4 may be used on Macs with Thunderbolt 2 and Thunderbolt ports via an adapter (sold separately), but this will not support notebook charging via Thunderbolt.

When your workflow needs change, the "FLEXpandability" of the OWC Flex 1U4 easily adapts. Add new drives, connect different devices, and install a half-length, full-height, single-width PCIe x16 card of your choice, like a 10Gb Ethernet networking card or the fast OWC Accelsior 4M2 SSD for expanded performance storage capacity. By not locking you into an inflexible single-task design, the OWC Flex 1U4 extends its useful life and maximizes your investment well into the future.

The OWC Flex 1U4 is like a bolt-in productivity supercharger for new or existing rack environments powered by a rack Mac Pro, rack PC, MacBook Pro, PC notebook, or even a Mac mini. Whether you build your own custom drive and card configuration or select one of OWC's convenient ready-to-run solutions, the OWC Flex 1U4 is ideal in a wide variety of settings:

• In School: perfect for taming ever-growing collections of digital files with easy integration and future drive capacity and performance scalability.
• At Work: adds Thunderbolt speed and swappable drives to server closets, server rooms, or colocation center backup capabilities.
• On Stage: handles all the storage and peripheral connectivity needs front-of-house pros require for live performances.
• On Set: easily fits into mobile DIT carts to capture multi-stream, hi-res footage at full framerate while daisy-chaining up to five additional Thunderbolt devices.
• In Studio: expands storage and connectivity options of fixed racks.
• At Home: great for installers creating a high-performance home entertainment server closet.

A hallmark of OWC FLEX technology is the ability to use U.2 NVMe SSDs, as well as the OWC ecosystem of U.2 drives and adapters. U.2 NVMe drives are specifically designed to maximize the PCIe bus and when combined with Thunderbolt, you'll blast past fast with real-world transfer speeds of up to 2750 MB/s. Whether you use your rackmount setup to complete massive backups faster, stream content during a live performance, edit large format video, or run high transactional and complex calculation applications, you can do it U.2 to it with the OWC Flex 1U4.

The OWC Flex 1U4 goes with the flow when needing to move data outside or beyond the local network. With the OWC U.2 ecosystem, moving and sharing data is fast and easy. Swap out and ship a project from field to post in video production workflows. Move backup data to an offline colocation for backup workflows. The combination of OWC Flex 1U4 and the OWC U.2 ecosystem opens a new dimension to data transfer possibilities.

• OWC U2 ShuttleOne: Convert an NVMe M.2 "blade" style SSD into a swappable 2.5" U.2 SSD with the peace of mind that your drive and its content are protected by the full metal, heat-dissipating adapter.
