A 3-port hub with Thunderbolt 4 compatible storage features that can be stacked with the Mac mini.

The OWC miniStack STX (hereinafter referred to as "this product") is a Thunderbolt hub equipped with storage capabilities that can accommodate M.2 NVMe SSDs and SATA hard drives/SSDs. Even on computers with a limited number of ports, such as laptops and small PCs, you can connect this product with a single Thunderbolt 4 cable to use multiple Thunderbolt/USB devices simultaneously. The body, which is the same size as the Apple Mac mini series, can be stacked on top of the Mac mini itself, allowing for the expansion of storage capacity and Thunderbolt/USB devices without changing the installation space.
