Repurpose and Maximise

With SSDs becoming more affordable and content continuing to grow, you’ve likely upgraded your Mac with a higher capacity drive. With the Accelsior 1A PCIe adapter card, you can repurpose that Apple factory SSD as a fast PCIe SSD to maximise your storage/backup space and technology investment.

Expanded High Speed Storage

The Accelsior 1A is a Plug and Play solution that gives the oft tossed aside factory SSD reimagined new life inside a 2019 Mac Pro, 2012 and 2010 Mac Pro, or PC tower with an open PCIe slot. It can even put that drive back to work externally in a PCIe expansion chassis like the OWC Mercury Helios 3S. (sold separately). By delivering the full speed and performance potential of the factory SSD via PCIe, the Accelsior 1A will let you enjoy:

  • Near instant start-up and business critical app launching
  • Real-time processing of intensive transfer tasks like multi-stream video editing
  • Shorter render, capture, and process times in video suites like Adobe Premier, Final Cut Pro/Pro X, DaVinci Resolve, and Avid Pro Tools
  • Quicker production capabilities in photo and audio platforms like Adobe Photoshop, Lightroom, and Apple Logic Pro X
  • Faster game level-loading, responsiveness, and save times
  • Added use life years of current machine vs a far costlier new one
