The Dual Drive Dynamo
Just as superheroes have an alter ego, so too does the miniStack STX. The universal SATA drive bay accommodates a hard disk drive or an SSD for storing large amounts of data. When you need instant access operations with low latency, the NVMe M.2 SSD slot unleashes the unbridled power of the miniStack STX. NVMe was developed to unlock the speed potential of modern flash drive technology by utilising a direct path to a computer’s processor via PCIe. This allows you to enjoy near-instant access performance with the miniStack STX.

Edit. Save. Access like a pro.
With multiple drive configurations available, you can experience real-world data transfer speeds of up to 770 MB/s. Move 5 GB of GoPro footage in around 6 seconds. Transfer thousands of photos from a priceless event in just a few seconds. Use the SATA drive for Time Machine or File History backups whilst you work with the NVMe drive. With this level of performance, the miniStack STX is ideal for multi-stream compressed 4K video editing, photography, audio, virtual machines and everyday data tasks.

Monitor and protect your data with ease
For even more performance 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 every drive. For over 25 years, SoftRAID has been the most comprehensive and powerful software RAID solution available for Mac and Windows. SoftRAID protects your data even before you start saving by checking whether the miniStack STX drives are safe for data storage.

In the unlikely event of a hard drive failure, your data will still be complete and accessible on the other drive in the miniStack STX! SoftRAID then continuously monitors your hard drives using a combination of S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) attributes and proprietary I/O statistics. This in-depth analysis of the hard drive’s condition identifies potential issues, allowing you to take preventative action. SoftRAID is available for both Mac and PC, enabling the miniStack STX to be shared across different computers.

Switching between Macs and PCs
Accessing your miniStack STX on a Windows PC is particularly easy with OWC’s MacDrive. This seamless software runs in the background, so you don’t need to launch anything or learn anything new. Simply connect the miniStack STX and you’ll have not only immediate read access, but full write access too! MacDrive also includes powerful features for formatting and partitioning drives, as well as repairing basic hard drive issues.

Expand your musical journey
Putting together your music setup can be daunting. With the two configurable drives of the OWC miniStack STX, it’s easy to create a storage powerhouse for recording and playing back important tracks in real time. You can even store your entire loop and sample libraries on the NVMe SSD for instant access with virtually zero latency.

Expand your connections
You’ll experience a new freedom when you can connect to virtually any past, present or future device or accessory via three Thunderbolt (USB-C) ports. Just like the miniStack STX’s innovative storage capacity, these three ports have a second superpower: they reinvent the daisy chain by allowing you to create three independent chains with up to five bus-powered Thunderbolt devices, with a USB device at the end of each chain (for a total of 8 devices). You can now also remove devices from one chain without affecting the other chain(s).

Expand your investment
If you own a 2018 Intel Mac mini or the latest Apple Silicon version, the fact that the internal factory drive cannot be upgraded is no longer a reason to sell your beloved little powerhouse. The miniStack STX maximises your investment in your mini with massive capacity for a fraction of the time and money you’d spend buying and setting up a new device. Even if you own a Mac, PC or device that only has USB-A, you’re not out of luck. With a USB-C to USB-A adapter cable (sold separately), you can use the miniStack STX’s SATA drive bay to transfer data to and from your computer and expand your tried-and-tested setup with additional features.
