Other World Computing has debuted the addition of the OWC Mercury Helios 2 PCIe Thunderbolt Expansion Chassis to its Helios line. It's a solution for using two single-width, or one single-width and one double-width, PCIe 2.0 adapter cards with the all new Mac Pro, Mac mini, iMac, MacBook Air, MacBook Pro, and other Thunderbolt-equipped computers that do not have PCIe slots due to size and/or design limitations.

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 Thunderbolt 2 equipped Mac Pro 2013 can enjoy the functionality and productivity gains of these PCIe cards.

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.

The OWC Mercury Helios 2 PCIe Thunderbolt Expansion Chassis will be available soon for US$479.99. For more details, go to http://tinyurl.com/me5855p .
