Overview
Not a pocket portable drive, the StudioStack is a desktop storage unit with a built-in hub, shaped to stack with a Mac Studio. NVMe flash handles the storage while Thunderbolt and USB-A ports on the hub connect other gear.
Storage and expansion share one chassis, so a single cable to the computer frees up more connections for drives, displays and accessories. The limitation is that it is a powered desk unit that adds an adapter and a cable run, and individual read and write speeds are not given.
Who it's for
A desk where a Mac Studio already stands and more ports are needed alongside fast storage. People moving files between locations, or those who only need a plain backup drive, will have a hub they never use.
Pros and cons
- Storage and hub in one chassis
- Thunderbolt 5 host connection
- USB-A ports for older accessories
- Cable and power adapter included
- Read and write speeds not listed
- Needs its own power adapter
- Desk unit, not a portable drive
- Only three USB ports
Performance notes
Speed is governed by the Thunderbolt link to the computer and by the NVMe drive inside, and the listing gives no measured read or write figures. Devices on the hub can share the same connection back to the computer, so heavy transfers and busy accessories may compete for bandwidth. Power delivery to a connected laptop draws on the supplied adapter.
