miniStack STX
Designed to stack perfectly with the Mac mini and the ideal storage and connectivity expansion companion for Thunderbolt or USB-equipped computers.
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. The miniStack STX now features Storage and Thunderbolt Xpansion, continuing its award-winning legacy as the best sidekick a Mac mini can have. Meet the world’s first Thunderbolt certified Thunderbolt 4 storage solution.
With a universal SATA HDD/SSD 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, and tablets. It also works with desktop accessories like a keyboard, card reader, or mouse. The possibilities of how you can use your Mac mini are now limited only to your imagination.

Xpands Notebooks, Tablets, and More
Sized identically to the Mac mini, the miniStack STX is also a sleek, complementary companion for MacBook and PC notebook and desktop machines, iPads, and Chromebooks. 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).5 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.
Easily Monitor and Protect Your Data
For even more power and security, add OWC’s SoftRAID software to your miniStack STX.
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.
Move Between Macs and PCs
Accessing your miniStack STX on a Windows PC is remarkably easy with the addition of OWC’s MacDrive. This seamless software runs in the background, so there’s nothing to launch or learn. Just connect the miniStack STX and not only do you have instant-read access, but full write access too! MacDrive also includes powerful features that enable you to format and partition drives as well as repair basic disk issues.

- OWC highly recommends that you verify the display support for your specific Mac model:
- OWC highly recommends that you verify the display support for your specific iPad model:
- OWC recommends that you verify the display support for your PC's Thunderbolt port. Some refresh rates require DisplayPort 1.4 HBR3 and DSC 1.2 support from the display and the host. Not all Thunderbolt ports support DisplayPort 1.4 – some are limited to DisplayPort 1.2, which may reduce refresh rate or resolution support.
Xpand Your Sonic Journey
Building your music setup can be daunting. With two configurable drives in the OWC miniStack STX, it’s easy to create a storage powerhouse for recording and playback of essential tracks in real-time. You can even store your entire loop and sample libraries on the NVMe SSD for in-a-flash use with near zero latency.5
Xpand Your Connections
You’ll experience newfound freedom when you’re able to connect to nearly any past, present, or future device/accessory via three Thunderbolt (USB-C) ports.2,3,4 Just like the miniStack STX’s innovative storage capability, these three ports have a second superpower: They reinvent the daisy chain by allowing you to create three independent chains with up to five total Thunderbolt devices with a USB device on the end of each chain (for 8 devices total). You can now also remove devices from one chain without affecting the other chain(s).
Xtend Your Investment
If you own a 2018 Intel Mac mini or the latest M1 version, the fact that the internal factory drive can’t be upgraded is no longer a reason to sell your beloved little powerhouse. The miniStack STX maximizes your mini’s investment with a mighty capacity punch for a fraction of the time and money you would spend in buying and setting up a new machine.
If you own a Mac, PC, or device equipped with USB-A only, you’re not left behind. With a USB-C to USB-A adapter cable (available separately), you can utilize the miniStack STX’s SATA drive bay to transfer data to/from your machine plus infuse your trusty setup with additional device connectivity.4,5
Store from Minutes to Millions
All the features and “technospeak” of an external drive don’t mean a thing if you don’t know how much of a particular file type it can hold. For every 1TB of miniStack STX capacity, you can store up to any of the following:6
250K

Keeps the Power Flowing
Whether you’re taking a short break or are done for the day, the miniStack STX keeps you powering ahead. No matter if your machine or STX goes into sleep mode, the STX’s Thunderbolt ports continue to power and/or charge connected devices. Your notebook will stay charged and ready too with up to 96 watts of power through its Thunderbolt or USB-C connection.4
Certified for Demanding Use
We understand having confidence in gear reliability is paramount to creative professionals. That’s why every miniStack STX goes through a multi-step performance certification prior to shipping. This ensures your miniStack STX arrives operating properly and immediately ready for demanding use.
Work with Ultimate Confidence
Active workspaces expose gear to unexpected bumps and shoves. OWC ClingOn custom cable stabilizers (available separately) screw into the OWC Dock or OWC Drive housing to reduce – if not completely eliminate – cable strain on Thunderbolt and USB-C connections so you can work with ultimate confidence even in the highest foot traffic environments.
- 28TB miniStack STX provides over 218x greater data storage than a 2018 Mac mini with factory equipped 128GB SSD.
- Works with Thunderbolt (USB-C), Thunderbolt/Thunderbolt 2 (mDP), and USB devices. Thunderbolt/Thunderbolt 2 (mDP) device support requires a certified Thunderbolt 3 (USB-C) to Thunderbolt 2 (mDP) adapter and a Thunderbolt 2 cable (available separately) and provides data transfer at up to 20Gb/s.
- Actual display support depends upon host. Please review the display specifications for your specific host system to determine the maximum supported resolution, refresh rate, color depth, and number of external displays over Thunderbolt or USB.
- Works with Thunderbolt 4, Thunderbolt 3, USB4, and USB host computers and mobile devices. Thunderbolt/Thunderbolt 2 Mac models are supported via USB-A host connection. Thunderbolt/Thunderbolt 2 host connection is not supported.
- With a USB host (such as a USB-C equipped MacBook, iPad, Chromebook, Android device, or PC), this device works as a USB hub. Bandwidth is reduced to USB speeds, Thunderbolt devices are not supported, and additional functionality will vary depending upon the host port's capabilities.
- With a USB-C host, displays and power delivery support will depend upon the host port's capabilities.
- With a USB-A host, displays and power delivery are not supported. Requires a USB-C to USB-A adapter cable (available separately).
- A USB host connection is required for Mac systems running macOS 10.14 or 10.15.
- NVMe SSD usage requires a Thunderbolt (USB-C) host connection with a compatible system running macOS 11.x or later. USB host connectivity provides SATA drive use only, and limits additional miniStack STX ports to USB connectivity only.
