Internal-Drive Speed and Room to Grow for Your Mac Studio

A maxed-out Mac Studio SSD fills up fast when you are editing 8K video or running local AI models. The OWC StudioStack adds that space at internal-drive speed, delivering up to 6302 MB/s over Thunderbolt 5 with a 20TB HDD and a bay for fast NVMe. Explore more OWC or other data storage.

Where It Fits

  • Mac Studio and Mac mini setups that need more fast storage than the internal SSD.
  • 8K video editing, large asset libraries, and local AI workflows.
  • Desks where it stacks neatly on top of or under the Mac.

  • Thunderbolt 5 up to 6302 MB/s: real-world speed that matches a Mac Studio's internal SSD.
  • Hybrid capacity: a 20TB HDD installed, plus an NVMe bay that supports up to 8TB of SSD.
  • Six-port hub: three Thunderbolt 5 and three USB-A ports for displays, drives, and devices.
  • Aircraft-grade aluminum with a smart adaptive fan that runs only when it is needed.
