OWC OWCT4MS9000 storage drive enclosure HDD enclosure Black 2.5/3.5"

Sized to stack with the mini. The ideal storage and connectivity expansion solution for all.

Mini Sized. Mammoth Possibilities.
Just like great duos Kirk and Spock, Frodo and Sam, or Woody and Buzz, the miniStack and the Mac mini have been the perfect pair since 2005. Now featuring Storage and Thunderbolt Xpansion, the miniStack STX continues its award-winning legacy as the best sidekick a Mac mini can have.
With a universal SATA HDD/SSD bay AND an NVMe M.2 PCIe SSD slot, you can expand your mini’s storage capacity to gigantic proportions. Three Thunderbolt (USB-C) ports enable you to connect to millions of Thunderbolt, USB, and future USB4 drives, displays, A/V mixers, cameras, tablets, and desktop accessories like a keyboard, card reader, or mouse. The possibilities of how you can use your Mac mini is now only limited to your imagination.2

Xpands Notebooks, Tablets and More
While sized identical to the Mac mini, the miniStack STX is a sleek, complementary companion for MacBook and PC notebook and desktop machines, iPads, and Chromebooks as well. While highly powerful, these machines are often limited in the number and variety of ports they offer. The miniStack STX solves that expansion limitation with a new world of increased connectivity and storage capacity.

The Dual Drive Dynamo
Just like superheroes have an alter ego, so too does the miniStack STX. The universal SATA drive bay holds a hard disk drive or SSD for upstanding data storage performance with big capacity. When you need to support bandwidth-intensive operations, the NVMe M.2 SSD slot reveals miniStack STX’s ferocious power. NVMe was designed to deliver the speed potential of modern flash drive technology by using a direct path to a computer’s processor over PCIe (see USB-C host note)3. As a result, you can enjoy near instant access performance with the miniStack STX.5

Edit. Save. Access. Like a Pro
With multiple drive configurations available, you can experience up to 770MB/s of real-world data transfer speed. Move 5GB of GoPro footage in about 6 seconds. Transfer 1000’s of photos of that priceless event in mere seconds. Use the SATA drive for Time Machine or File History backups while working off the NVMe drive. With heavyweight performance like this, the miniStack STX is great for multi-stream compressed 4K video editing, photography, audio, virtual machines, and everyday data tasks.

Xpand Your Sonic Journey
Building your music setup can be daunting. With two configurable drives in the OWC miniStack STX, it’s easy to create a storage powerhouse for recording and playback of essential tracks in real-time. You can even store your entire loop and sample libraries on the NVMe SSD for in-a-flash use with near zero latency.5

Xpand Your Connections
You’ll gain a newfound freedom by being able to connect to nearly any past, present, or future device and accessory via three Thunderbolt (USB-C) ports.2,3,4 Just like the miniStack STX’s innovative storage capability, these three ports have a second super ability. They reinvent the daisy chain by allowing you to create three independent chains with up to five bus-powered Thunderbolt devices with a USB device on the end of each chain (for 8 devices total). You can now also remove devices from one chain without affecting the other chain(s).

Xtend your Investment
If you own a 2018 Intel Mac mini or the latest Apple silicon version, the fact that the internal factory drive can’t be upgraded is no longer a reason to sell your beloved little powerhouse. The miniStack STX maximizes your mini’s investment with a mighty capacity punch for a fraction of the time and money you would spend in buying and setting up a new machine.
If you own a Mac, PC, or device equipped with USB-A only, you’re not left behind. With a USB-C to USB-A adapter cable (available separately), you can utilize the miniStack STX’s SATA drive bay to transfer data to/from your machine plus infuse your trusty setup with additional device connectivity.

Store from Minutes to Millions
All the features and “technospeak” of an external drive don’t mean a thing if you don’t know how much of a particular file type it can hold. For every 1TB of your OWC drive capacity, you can store up to any of the following:

- 250,000 photos
- 250,000 standard quality songs
- 38,000 high quality songs
- 200 high-definition movies
- 41.6 hours of GoPro 4K footage
- 4.3 million MS Office documents
- 24+ PS4/Xbox games

Keeps the Power Flowing
Whether you’re taking a short break or are done for the day, the miniStack STX keeps you powering ahead. No matter if your machine or STX goes into sleep mode, the STX’s Thunderbolt ports continue to power and/or charge connected devices. Your notebook will stay charged and ready too with 96 watts of power through its Thunderbolt or USB-C connection.4

Secure Your Connections
Unexpected disconnects during file transfers or a work session can be devastating. The OWC ClingOn (sold separately) easily reduces – if not eliminates – cable strain on the miniStack STX Thunderbolt connection ports.
