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 performance. When you need to support low latency instant access operations, the NVMe M.2 SSD slot reveals miniStack STX’s ferocious nature. 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. As a result, you can enjoy on-demand high 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 and create a RAID 1 to automatically maintain identical copies of all your data on each drive. For over 25 years, SoftRAID has been the most fully featured and powerful software RAID solution available for Mac and Windows. It starts protecting your data even before you start saving by validating the miniStack STX drives are safe for data storage. In the improbable event that you experience a disk issue, your data is still complete and accessible on the miniStack STX’s other drive! SoftRAID then constantly monitors your disks with a combination of S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) attributes along with its own I/O statistics. This deep dive disk health analysis identifies potential problems so you can take preventive action. SoftRAID is available for both Mac and PC making it possible to share the miniStack STX between computers.
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.

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.
Xpand Your Connections
You’ll experience a newfound freedom when you’re able to connect to nearly any past, present, or
future device/accessory via three Thunderbolt (USB-C) ports. 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. You’re not left behind if you own a Mac, PC, or device equipped with USB-A only. 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.
