OWC Releases Mercury Helios PCIe Thunderbolt Expansion Chassis Updated with Thunderbolt 2 Technology for Amazing 20Gb/s Performance

Enables Use of Half-Length, Single-Width, Professional-Level PCIe 2.0 Cards with Thunderbolt-Equipped Macs

Jan 5, 2015 | Woodstock, IL


Other World Computing (OWC), a leading zero emissions Mac and PC technology company, announced today that the OWC Mercury Helios PCIe Thunderbolt Expansion Chassis has been updated with Thunderbolt 2 technology. The newly updated Helios handles throughputs of up to 20Gb/s, bringing Thunderbolt 2 technology to the original Mercury Helios' throughput of up to 10Gb/s. OWC's Mercury Helios PCIe Expansion Chassis is the ideal solution for using half-length professional-level PCIe 2.0 cards with Apple's entire line of Thunderbolt enabled Macs that do not have PCIe slots due to size or design limitations.

Now More Users Can Tap into the 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, users of portable and all-in-one computers can enjoy the functionality and productivity gains of these PCIe cards wherever their work takes them.

Boosts Workflow Productivity
Mercury Helios is fast and flexible with a throughput of up to 20Gb/s, and is the perfect solution to boost workflow productivity. It is bootable with AHCI-compliant cards and can daisy-chain up to five additional Thunderbolt devices. Types of PCIe cards Helios can use include: Fibre Channel, 10GB Ethernet, RAID controller, video capture, digital audio, solid state drives, SAS controllers such as the OWC Jupiter, as well as FireWire, USB 3.0, eSATA host adapter cards.

Pricing and Availability
Offered with a $299.00 MSRP, the Mercury Helios PCIe Thunderbolt Expansion Chassis is now available for order and will begin shipping within 7-10 days directly from OWC and select retailers.
