Product Description
Experience the next evolution in portable storage with the OWC Express 1M2 80G. Built on the latest Thunderbolt 5 / USB4 80Gb/s interface, this aircraft-grade aluminum, finned, fanless enclosure/caddy delivers over 6000MB/s real-world performance with pro-level thermal control. Run 8K video edits, VFX renders, AI/ML workloads, high-volume photo ingest, and game builds at internal-SSD speeds — anywhere, bus-powered, with a single cable. Choose a flexible DIY kit (add your own 2242/2280 NVMe) or a Ready SSD configuration, and work across Mac, PC, iPad Pro, Surface, and Chromebooks with simple cross-platform options like MacDrive (optional).
Highlights
- Supremely fast: over 6000MB/s peak real-world speed via Thunderbolt 5 80Gb/s
- DIY or Ready SSD: supports M.2 NVMe 2242/2280 (no heatsinks).
- Ready-made SSD configuration: See product options (ready-made SSD will come with OWC Aura Pro IV)
- Innovatively cool: deep-finned, fanless aluminum design for sustained speed
- Widely compatible: Mac, PC, iPad Pro, Surface, Chromebooks
- Bus-powered: one cable convenience with included USB4 cable
- Pro-grade use: 8K video/VFX, AI/ML, photography, gaming, and more

- NVMe M.2 SSDs with 2280 / 2242 / form factor
Double-Sided | Single-Sided NVMe M.2 SSDs
PCIe Gen 3.0, Gen 4.0, and Gen 5.0 NVMe SSDs - Compatibility Notice: ⚠️ Western Digital SN5xx series NVMe M.2 2280 SSDs are not compatible with the OWC Express 1M2 80G Thunderbolt 5/USB4 NVMe SSD Enclosure and should not be used.
-
Users should expect the following speeds when connected to a Thunderbolt 5 or USB4 v2 host:
PCIe Gen 3.0: up to 3400 MB/s
PCIe Gen 4.0: up to 6800 MB/s
PCIe Gen 5.0: up to 6800 MB/s (limited by Thunderbolt/USB interface) - PCIe Gen 5 NVMe M.2 SSDs require careful selection and verification of manufacturer specifications due to the bus-power limits of host computers, docks, and hubs. We recommend choosing a PCIe Gen 5 SSD that consumes 11 watts or less on average during sustained read or write operations, such as the Samsung 9100 Pro Series Gen 5 NVMe.
