Some ways you can use the OWC Accelsior 1A:

  • Migrate data from your existing drive to a larger capacity upgrade drive
  • Access/recover data from a drive removed from an inoperative machine
  • Increase your data storage capacity

Extend your SSD Upgrade Path

After you add a higher capacity OWC Aura PCIe SSD to your Mac, the Accelsior 1A PCIe Adapter Card completes the upgrade path. Use your old drive to add more internal storage and unlock performance capabilities in any machine with an available PCIe slot, including Mac Pro towers, desktop PCs, and more.

Perfect Outside Too
