Expand Your Mac’s Potential with the OWC miniStack STX

Designed to match the footprint of the Mac mini and Mac Studio, the OWC miniStack STX offers a seamless blend of high-capacity storage and advanced connectivity. Whether you’re a creative professional or simply looking to expand your desktop’s potential, this enclosure delivers the performance and flexibility to keep your workflows running efficiently.

Elegant Design, Practical Expansion

The miniStack STX is engineered to stack perfectly with your Mac mini (2012–2023) or Mac Studio, transforming your setup into a streamlined and powerful workspace. It adds over 200 times the internal storage of a base Mac mini and more than 50 times that of a Mac Studio. The compact, minimalist form ensures it complements your device without taking up additional desk space.

Dual-Drive Power and Versatility

Inside, the enclosure houses both a universal SATA bay for 2.5" or 3.5" HDDs/SSDs and an NVMe M.2 PCIe SSD slot. This combination provides the perfect balance between massive capacity and ultra-fast performance. Access and back up files, edit 4K video, and launch applications with real-world speeds up to 770MB/s.

Connectivity That Evolves With You

Three Thunderbolt (USB-C) ports expand your desktop’s capabilities, supporting a wide range of devices including displays, storage drives, audio interfaces, and peripherals. These ports allow for daisy-chaining up to five Thunderbolt devices, with support for USB accessories at the end of each chain, ensuring future compatibility across your setup.

Designed for All Devices

While tailored for Mac users, the miniStack STX works seamlessly with USB-C and Thunderbolt-equipped PCs, iPads, and Chromebooks. For legacy systems with USB-A ports, an adapter (sold separately) enables full access to the SATA drive and connectivity features, making this a truly universal storage solution.

Ideal for Professional Workflows

The miniStack STX is optimised for high-performance tasks such as multi-stream 4K video editing, audio production, and working with virtual machines. Use the NVMe SSD for low-latency operations while backing up with the SATA drive via Apple Time Machine or Windows File History, all without compromising speed or reliability.

Power Delivery and Efficient Cooling

Delivering up to 96W of power through Thunderbolt or USB-C, the miniStack STX keeps your laptop or connected device charged while you work. An aluminium housing with an internal heat sink and high-efficiency fan ensures quiet, cool operation—even during intensive workloads.

Advanced Software Options

Upgrade your setup with OWC’s SoftRAID software (optional), which provides powerful drive management, performance optimisation, and multiple RAID configurations. Ideal for users needing greater data protection, speed, or both, it brings enterprise-level tools to your desktop.

Cross-Platform File Access

With OWC’s MacDrive software (available separately), transferring files between macOS and Windows becomes effortless. Read, write, and manage Mac-formatted drives directly from a Windows PC without complex setup, ensuring seamless workflow in mixed operating system environments.
