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.

Ready to Go. Right Out of the Box.

OWC products are loved around the world for It Just Works™ ease-of-use and reliability. To provide the highest performance, reliability, and ready-to-run convenience available, your solution comes formatted in the native APFS macOS and iPadOS file system. With OWC, you don’t have to worry about reformatting hassles or confusion like other solutions — just plug your drive into your Mac or iPad and you’re good to go.

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.

Most unopened items sold by Melrose Inc. in new condition and returned within 30 days will receive a refund or exchange. The return window for items sold online begins once the order has been invoiced. Invoicing happens when any part of the order is shipped, delivered by a courier service or made ready for pick up.

Software is not returnable and not refundable. All sales are final. This is generally part of all webcarts selling software. It is buyer beware. The reason for this is once an end-user customer sees a License Code then that code is 'spoiled' because they can use it to gain access to the software.  Once a License Code is registered by a customer that product is available to that customer and therefore the code cannot be returned.
