General Information:

Mini Sized. Mammoth Possibilities.

Just like great duos Kirk and Spock, Frodo and Sam, or Woody and Buzz, the miniStack and the Mac mini have been the perfect pair since 2005. Now featuring Storage and Thunderbolt Xpansion, the miniStack STX continues its award-winning legacy as the best sidekick a Mac mini can have.

With a universal SATA HDD/SSD bay AND an NVMe M.2 PCIe SSD slot, you can expand your mini's storage capacity to gigantic proportions. Three Thunderbolt (USB-C) ports enable you to connect to millions of Thunderbolt, USB, and future USB4 drives, displays, A/V mixers, cameras, tablets, and desktop accessories like a keyboard, card reader, or mouse. The possibilities of how you can use your Mac mini is now only limited to your imagination.

Xpands Notebooks, Tablets and More

While sized identical to the Mac mini, the miniStack STX is a sleek, complementary companion for MacBook and PC notebook and desktop machines, iPads, and Chromebooks as well. While highly powerful, these machines are often limited in the number and variety of ports they offer. The miniStack STX solves that expansion limitation with a new world of increased connectivity and storage capacity.

The Dual Drive Dynamo

Just like superheroes have an alter ego, so too does the miniStack STX. The universal SATA drive bay holds a hard disk drive or SSD for big capacity data storage. When you need to support low latency instant access operations, the NVMe M.2 SSD slot reveals miniStack STX's ferocious power. NVMe was designed to deliver the speed potential of modern flash drive technology by using a more direct path to a computer's processor over PCIe (requires Thunderbolt host). As a result, you can enjoy near instant access performance with the miniStack STX.

Edit. Save. Access. Like a Pro

With multiple drive configurations available, you can experience up to 770MB/s of real-world data transfer speed. Move 5GB of GoPro footage in about 6 seconds. Transfer 1000s of photos from that priceless event in mere seconds. Use the SATA drive for Time Machine or File History backups while working off the NVMe drive. With heavyweight performance like this, the miniStack STX is great for multi-stream compressed 4K video editing, photography, audio, virtual machines, and everyday data tasks.

More Powerful With SoftRAID

Need more power and protection? Choose a solution that includes OWC's powerful SoftRAID RAID software.

SoftRAID is the most powerful, intuitive software RAID utility on the market. Multiple RAID levels let you select the RAID level that fits you or your project's needs best. If you need maximum volume capacity, optimum drive performance, data protection, or a combination of attributes, SoftRAID has you covered.

Packed with features like drive validation, verification and failure prediction-SoftRAID includes features you simply don't get with hardware RAID. It's like having a datacenter on your desktop! From home users looking to protect photos and documents to professionals needing to protect and quickly access projects, SoftRAID is the perfect solution.
