The OWC Express 4M2 is OWC’s fastest USB4 40Gb/s NVMe SSD RAID enclosure, engineered to deliver peak performance for USB4, Thunderbolt, and USB-C Macs and PCs. Designed with creative professionals and power users in mind, it allows you to configure your ideal desktop or portable RAID setup with up to four NVMe M.2 SSDs, reaching speeds of up to 3200MB/s. Its solid aluminum enclosure efficiently dissipates heat, while smart, adaptive fans activate only when needed—ensuring quiet, throttle-free performance during demanding tasks like high-speed backups, large media transfers, and intensive 8K video or RAW photo editing. Cross-platform compatibility with Mac and PC is made easy using OWC’s MacDrive software (sold separately), making the Express 4M2 a powerful and flexible solution for any workflow.
