OWC Express 4 M2 USB 4 Desktop Enclosure with Four-slot for NVMe M.2 SSD

Other World Computing (OWC) announced the launch of the OWC Express 4M2, a 4-slot NVMe M.2 SSD USB4, Thunderbolt compatible enclosure offering improved performance, thermal protection for today’s high performance drives, as well as expanded compatibility for an improved near-silent operation.

The Express 4M2 is made for the most demanding work. It’s built to keep up whether you’re backing up footage on set, editing 8K video, or sorting through 1,000s of high-res photos. It supports up to 4 NVMe M.2 SSDs (2230, 2242, or 2280) and achieves real-world speeds up to 3,200MB/s – and, with flexible RAID options, i.e., 0, 1, 4, 5, and 1+0, users can create the setup that works best for their workflow. Whether that’s max performance, redundancy, or a mix of both. And even when things get intense… multi-camera offloads, long editing sessions, big batch processing, the aluminum shell and smart fans keep it cool and quiet so you’re not dealing with slowdowns, overheating, or distracting noise. It’s fully compatible with USB 4, Thunderbolt, and USB-C, so whether you’re working on a Mac or PC, it fits right in and works seamlessly, with no fuss.

“We built the original Express 4M2 to give professionals the speed and flexibility they need – but we’re always listening and looking for ways to improve,” said Larry O’Connor, founder and CEO, OWC. “Our customers told us they wanted the same performance in a quieter, more adaptable solution. So that’s exactly what we delivered. With the addition of USB4 and smart thermal controls, this new version offers faster speeds, more RAID options, and broad compatibility – giving users the tools they need to work efficiently, without distractions.”
