OWC Mercury Helios PCIe Thunderbolt Expansion Chassis for Thunderbolt Macs
Want to expand your MacBook Pro with a PCIe card?
OWC’s Mercury Helios Thunderbolt Expansion Chassis accepts a PCIe card and connects to any Mac with a Thunderbolt port, such as a MacBook Pro.
For example, a MacBook Pro user could connect the Helios with a PCIe SSD up to 960GB, for lighting-fast external storage, say for a Photoshop or Lightroom or video drive.
Daisy-chaining more than one Helios unit allows further expansion.
