As Fast as Your Computer or Device
The Express 1M2 is the fastest single portable SSD we offer and was purposefully built to maximize the performance capabilities of today and tomorrow's USB4 equipped Macs and PCs. Experience up to an astonishing 3151MB/s speed when you use the Express 1M2 with most Macs and PCs you own from 2020 and newer. You can also enjoy highly effective performance (yep...you can edit 4K video no problem) and flexible compatibility with millions of yesterday's Thunderbolt and USB-C machines and devices
Don't Get Fooled
Because we're widely considered the Thunderbolt experts and work very closely with Intel, we know all the little details that others overlook. While specific OWC solutions are certified for full speed on Thunderbolt, we (and everyone else) are limited to half that speed with DIY enclosures. USB4 unleashes the Express 1M2 performance capabilities so you can build the drive of your dreams. Unlike budget brand pretenders that do not follow Intel specifications - and will leave you feeling fooled and disappointed in far lower speeds - the Express 1M2's USB4 connectivity assures you of the maximum speed and reliability you count on and expect from every OWC solution.
The Power of DIY
Build your Express 1M2 with a brand-new drive. Retask an existing drive replaced during an upgrade. Or make it simple by choosing a pre-built proven OWC reliable solution. Whatever your decision, Express 1M2 gives you the power to make it happen.
Use Today's and Tomorrow's Drives
Designed to support any NVMe M.2 2230, 2242, or 2280 SSD, the Express 1M2 gives you the freedom of flexibility to use any drive today - including OWC Aura SSDs up to 8.0TB capacity - as well as being ready for tomorrow's 16TB and future capacities without limit.
Built to Handle Demanding Needs
You'll never have to worry about thermal throttling because form meets function with the Express 1M2. Its solid aluminum heat sink design ensures proper heat dissipation so you can depend on consistent maximum performance. Unlike a snap together toolless enclosure, Express 1M2 screws together to securely protect your drive inside its rugged enclosure. And when you need to share the Express 1M2, it can work cross-platform with Macs and PCs using OWC MacDrive software (available separately) for peace between the platforms.

Your Data’s Reliability is Our #1 Priority
Anyone can put a bunch of components in a housing and call it an enclosure or a drive. OWC is not just anyone. We’re a group of filmmakers, musicians, designers, content creators, and parents just like you wanting to capture and preserve that irreplaceable moment. Our data storage products go through countless hours of ongoing development testing and certification processes. We then subject them to extreme real-world abuses. The priority for some drives is to be a mass-produced, lowest price commodity. We do it differently because the reliability of your data and the longevity of an OWC product is priority #1.

At OWC, it is our mission to deliver that seamless level of experience to you with every solution that we make, and in every interaction that we have. We are working to build a better world through our solutions, and it is our mission to create solutions that improve the lives of everyone that touches them. At OWC we promise to: Respect your time. Whether that is through our solutions that aim to get the tech out of the way and keep it out so you can focus on what’s important to you or through our service getting you the advice or help you need. Maximize your budget. That means in the short term in having fair prices, but most importantly in the long term by focusing on quality solutions that are built to last. Our solutions aren’t the cheapest because we know how much of a pain it is to swap out parts in your set up and we know how much you rely on your OWC gear. Support you. Every solution is backed and supported by knowledgeable representatives, not just before the sale, but during and after. You can always call, email or chat with OWC over the lifetime of the product.

External drive solutions are additionally tested after assembly, with some tests taking hours or even days to certify that they will go the distance. Channel you. Our solutions are tested using many different workflows so we can ensure when you plug it in, it just works. Complete the circle. There are many, many different options out there and while our hardware and software solutions are designed to work together, they are also designed to work within your setup. What We Do We empower our customers to take their technology further and ensure the investment that they made a couple years ago doesn’t have to be thrown out the door and recycled for something new. How It All Started “I started OWC because it was difficult for me to get to a local store to upgrade my own Apple. On top of that, it was very very expensive to do so and it drove me to number one do my own updgrades, but share that information and offer these upgrades so that others can benefit the same.” Environmental Sustainability We have worked tirelessly to build sustainable practices into all levels of our business operations. Join Our Team At OWC we strive to empower our customers through groundbreaking advancements in upgrades and solutions for Mac, PC, and mobile devices. With an emphasis on superior service, quality, value, and environmental responsibility, we are committed to the creation of technology that inspires the imagination and a world where everything is possible.
