Description
The Ultimate Creation ToolGive yourself the ultimate in creative power by building the portable drive of your dreams or choosing an advanced technology OWC Aura SSD powered OWC Express 1M2. Whether repurposing a drive, starting with a new drive, or wanting the convenience of a ready-to-run solution, you will infuse your workflow with the highest performance and reliability with an Express 1M2.
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.
Express 1M2 is Ideal for...
Photo and video professionals wanting an affordable yet solid editing drive that can be used both to backup and edit demanding content including 8K RAW video, 4K video in slow-motion, ProRes and other demanding codecs, and ultra-high resolution pictures both in RAW and compressed formats.
DITs looking to assemble the NVMe of their choice while also getting maximum offload speeds (faster than Thunderbolt) and thermal stability.
Prosumers/performance enthusiasts seeking an external enclosure to clone data from an internal drive at blazingly fast speeds.
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.

There is a possibility of the phone having minor scratches or scuffs on the screen and/or housing (the Back to you and me) including general wear and tear around the ports. This is a fully functional phone. Again the difference between a grade B phone and a new phone is the lack of the original box and/or accessories.
