Apr 5, 2014 | Las Vegas, NV


Other World Computing (OWC®), a leading zero emissions Mac upgrade and storage technology, will feature the OWC Mercury Helios 2 PCIe Thunderbolt Expansion Chassis along with its growing family of Thunderbolt interface storage products at the National Association of Broadcasters (NAB) show in Las Vegas this week, at booth #SL14016. The Helios 2 is a solution for using two single-width, or one single-width and one double-width, PCIe 2.0 adapter cards with the Mac Pro 2013, Mac mini, iMac, MacBook Air, MacBook Pro, and other Thunderbolt interface computers that do not have PCIe slots due to size and/or design limitations.

More Users Can Now Tap Into Power of PCIe and Thunderbolt
Desktop workstations used to be the only way computer users could access high-performance PCIe cards made for video capture/editing, media transcoding, audio processing, and data storage. Now, with Mercury Helios or Helios 2, users of portable, all-in-one computers, and the new Mac Pro 2013 with two Thunderbolt ports can enjoy the functionality and productivity gains of these PCIe cards wherever their work takes them.

The original Mercury Helios is fast and flexible with throughput up to 10Gb/s, while the Helios 2 handles throughputs of up to 20Gb/s, and is the perfect solution to massively boost workflow productivity. Both are bootable with AHCI compliant cards and can daisy-chain up to six devices.

  • Expansions slots: (2) PCIe 2.0 x 8 (x4) mode
  • Up to 20Gb/s data transfer
  • Daisy-chain up to six devices
