Small in stature. Big on capability. The OWC Express 4M2 is ready to serve with four easy-to-access NVMe M.2 SSD slots customizable for any workflow with vibration damping feet that allow for vertical or horizontal orientation. Install up to 32TB of capacity and experience up to 2800MB/s of mind-bending performance via Thunderbolt 3. The Express 4M2 is an amazingly small digital workhorse with world-renowned OWC quality and award-winning support built in.
Built Smaller and Faster from Input by Pros Like You.
The OWC Express 4M2 is designed with superior ease-of use in mind. We worked with award-winning creatives and listened to the kudos they heaped onto the OWC ThunderBay mini, and we put all that shared knowledge to good use when we set out to build the next-gen Thunderbolt 3 multi-bay drive. The result is the 57% smaller and 2.5x faster OWC Express 4M2.
It's smaller and easier to fit into your workflow, studio and on stage. It's faster with four easy-access M.2 slots so you can swap, upgrade or expand your Express 4M2 to configure and reconfigure it to serve any project need.
Game-Changing NVMe SSD Performance
NVMe (Non-Volatile Memory Express) is a hyper-efficient communications interface protocol built from the ground up to properly take advantage of SSD technology and high-performance connection buses like PCIe. The result is exponentially faster and efficient SSD storage, and the OWC Express 4M2 has room for four NVMe SSDs.
Easy and Complete Drive Management with SoftRAID XT
SoftRAID XT is the most powerful, intuitive RAID management software on the market for macOS and Windows. SoftRAID’s RAID creation and management technology has been finely tuned to perfection with over 20 years of development to provide rock solid protection of your data and optimize drive performance. It is packed with features like multiple RAID options, validation and verification of drives, and predictive disk failure with SoftRAID Monitor. SoftRAID provides a level of performance that you simply can’t get with hardware RAID.
Multiple RAID Levels
Create advanced RAID 0/1/4/5/1+0 (10)1 volumes for higher performance and/or redundancy.2
More accurate than SMART, SoftRAID protects your data by alerting you to issues before anything happens, providing peace of mind and giving you more time to address issues. Solutions that rely exclusively on SMART data can be seeing performance loss or corruption before flagging an issue.
Built-in MacDrive technology lets you read/write SoftRAID HFS+ RAID 0/1/5 arrays and use them interchangeably between Windows and macOS.
With SoftRAID you’re not locked to expensive hardware. SoftRAID is upgradable and portable.
Easy License Management
New license management enables quick activation or deactivation so your license can move between computers.
Works with macOS 10.12 or later and Windows 10 and later.3
SoftRAID is ideal for anyone who needs to safely store and backup massive amounts of data, including video editors, audio producers, photographers and graphic designers.
- RAID 4/1+0 (10) is available for Mac only at this time.
- Improved data protection/redundancy requires RAID 1/4/5/1+0.
- SoftRAID serial numbers work on both Mac and Windows. SoftRAID is licensed per computer. In order to use SoftRAID on multiple computers, you will need a unique, valid license per computer. Additional licenses can be purchased anytime.
Configure and reconfigure your storage however you need by combining multiple OWC Express 4M2 drives together on Mac and Windows. With OWC SoftRAID (included with Express 4M2) you get the amazing capability to RAID across multiple drive enclosures. On a Windows PC, add more Express 4M2 drives to your storage pool using Windows Storage Spaces.
Display connection flexibility is yours with a convenient DisplayPort located right on the rear of the OWC Express 4M2. There's no need to worry about adapters or extra long cables. Just plug your display directly into the Express 4M2 and you're all set.
Thunderbolt Made Easy
We make it easy to choose the right gear. Our Thunderbolt Certified products offer the same performance and functionality whether they are Thunderbolt 3 or Thunderbolt 4. And if you’re rocking a beloved Thunderbolt 2 machine, we offer an adapter so you can plug into our universe of award-winning solutions. No hassles, no confusion. That’s the OWC Difference.
Apple Mac models with Thunderbolt 2/Thunderbolt ports can be connected using an Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter and a Thunderbolt 2 cable (available separately). This configuration provides data transfer at up to 20Gb/s but does not support notebook charging.
