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.
