It features a USB Type-C interface and supports both M.2 and Serial ATA III storage drive interfaces. This enclosure provides a reliable solution for expanding your storage capacity, offering high-speed data transfer and compatibility with various drive types for professional and personal computing needs.

## Long description

The OWC miniStack STX is a high-performance storage enclosure designed to expand the capabilities of your Mac mini, notebook, or desktop computer. Featuring a sleek, compact design that matches the footprint of a Mac mini, this versatile device offers a dual-drive configuration with a universal SATA HDD/SSD bay and an NVMe M.2 PCIe SSD slot. With three Thunderbolt (USB-C) ports, it provides extensive connectivity for peripherals, displays, and external drives, making it an essential tool for professionals and power users who require reliable, high-speed storage and expanded port access.
Advantages
The OWC miniStack STX stands out by offering a unique combination of massive storage capacity and high-speed data transfer. By supporting both traditional SATA drives and ultra-fast NVMe M.2 SSDs, it allows users to balance cost-effective bulk storage with high-performance flash technology for demanding tasks. The integrated Thunderbolt hub functionality transforms a single connection into a powerful workstation interface, enabling the daisy-chaining of multiple devices while providing up to 96W of power delivery to keep your connected notebook charged. Its robust build quality and rigorous multi-step certification process ensure that your data remains secure and accessible even under heavy professional workloads.
Suitable for
Multi-stream 4K video editing and post-production
Professional photography and large-scale image library management
Audio recording and sample library storage
Virtual machine hosting and development environments
Expanding storage for Mac mini, MacBook, and PC workstations
When it may not be suitable
This enclosure may not be the ideal choice for users who require a portable, bus-powered drive for travel, as it requires an external power source to function. Additionally, it is primarily optimized for Thunderbolt-equipped systems, and while it can work with other configurations via adapters, users without Thunderbolt ports may not experience the full bandwidth and connectivity benefits of the device.
Key specifications
Drive support: One 2.5-inch or 3.5-inch SATA HDD/SSD and one NVMe M.2 PCIe SSD
Connectivity: Three Thunderbolt (USB-C) ports
Data transfer speeds: Up to 770MB/s depending on drive configuration
Power delivery: Up to 96W for connected devices
Compatibility: Mac and Windows systems
How to use
To set up the OWC miniStack STX, simply install your chosen SATA drive into the universal bay and insert your NVMe M.2 SSD into the dedicated slot. Once the drives are secured, connect the enclosure to your computer using a Thunderbolt cable. The device is immediately recognized by your operating system, allowing you to format the drives as needed. For advanced data protection, you can utilize RAID software to mirror your data across both drives, ensuring redundancy. The Thunderbolt ports on the back can then be used to connect additional monitors, card readers, or other USB peripherals to complete your workstation setup.
What to consider before purchase
Ensure your computer has a Thunderbolt or compatible USB-C port to achieve optimal performance.
Consider whether you need the high-speed performance of an NVMe SSD or the high-capacity storage of a traditional SATA HDD.
Check if you require additional adapters if your host machine only supports USB-A connections.
Verify if your specific workflow would benefit from RAID configurations for data redundancy.
Usage recommendations
For the best performance and data security, we recommend using the NVMe M.2 slot for your active working files and operating system, while utilizing the SATA drive bay for backups and long-term storage. Regularly monitor drive health using S.M.A.R.T. tools to prevent potential data loss.
