Expand the utility of your Thunderbolt 4 device and streamline your workflow with the matte silver 21TB miniStack STX & Thunderbolt Hub Xpansion from OWC / Other World Computing. This model combines a 1TB PCIe 4.0 x4 M.2 2280 SSD, which is designed for low latency instant access operations that include gaming as well as photo, video, and audio editing, with a 20TB 7200 rpm SATA 3.5" hard drive, which is well suited for large data storage needs and everyday tasks, such as backups, photos, music, and documents. Both the NVMe PCIe M.2 2280 slot and 3.5/2.5" drive bay are user accessible. No matter what you're doing, the miniStack is there to help you store large files and connect high-powered devices so you can work efficiently.





The miniStack connects to your host system using a Thunderbolt 4 port that provides up to 96W of Power Delivery, while three additional Thunderbolt 4 ports provide 15W of power and may be used to connect additional peripherals, including keyboards, mice, and up to two displays. These three ports may also be used to create a daisy chain, with up to five Thunderbolt and three USB devices on each, for a total of eight device per chain. Designed to work in various environments, the miniStack STX supports multiple platforms including macOS 10.14 to 14, Windows 10 (32/64-bit), Windows 11, Windows Server 2022, Windows Server 2019, Linux, iPadOS 14 to 17, Android 11.x to 13.x, and Chrome.





Please note that this configuration requires a 40 Gb/s Thunderbolt 4, Thunderbolt 3, or USB4 host connection with a compatible system running macOS 11.x or later. Connecting the miniStack STX to a USB-C or USB-A host requires macOS 10.14.6 or later, but will only allow for the use of its SATA drive bay and will only let the Thunderbolt ports be used as a USB hub for accessories. Also, please bear in mind that the maximum performance of the internal M.2 NVMe SSD is 770 MB/s because of bandwidth limitations of the system's PCIe 3.0 x1 bus.
