Today's ultra-light notebooks, mini, and all-in-one desktop computers now have tremendous processing power-power that many thought would only be possible in full-size workstation or large desktop computers. Smaller in size and more portable, they're very desirable. For pros in the creative fields, processing power alone is not enough. A prime example is the new Mac Pro. Proven to be a processing powerhouse and packed with Thunderbolt 2 and USB 3.0 ports, it lacks the PCIe expansion slots necessary to install specialty cards to connect various video and audio inputs for transcoding data, and to connect to high-speed storage and networks. With the Echo Express III-R, Sonnet has created a solution that leverages the paradigm shift enabled by Thunderbolt technology, allowing PCIe expansion slots to be connected outside a computer. This rackmount Thunderbolt-to-PCIe card expansion chassis makes it possible for you to connect three professional video capture, audio interface, SAS or SATA HBA, 16Gb or 8Gb Fibre Channel, 10 Gigabit Ethernet, and RAID controller PCIe cards to any Mac with a Thunderbolt port.

Three Slots
Sonnet's Echo Express III-R supports three full-size PCIe cards, up to 12.28" (full-length). The III-R integrates a universal 300W power supply and includes a 75W PCIe power connector for cards that require supplementary power, such as the Avid Pro Tools|HDX or the new RED ROCKET-X. Even with all that power, the III-R is enviro-friendly; it automatically powers on or off whenever the connected computer powers on or wakes, or powers off or sleeps, respectively. The use of large, slow-spinning fans in the Echo Express III-R makes it a remarkably quiet operator. Two Thunderbolt ports support daisy chaining of up to six devices to a single port on your computer.

Built for Speed
20Gbps Thunderbolt 2 technology-equipped computers are here. The original 10Gbps Thunderbolt interface has provided breakthrough bandwidth for external expansion, more than sufficient to support the maximum performance of most PCIe cards. However, some high bandwidth cards such as the RED ROCKET, 16Gb Fibre Channel, multi-port 10 Gigabit Ethernet cards, or the use of other bandwidth-hungry cards require more than 10Gbps. Thunderbolt 2 removes this barrier by providing more bandwidth for demanding applications. The Echo Express III-R's Thunderbolt 2 interface takes full advantage of this increased bandwidth to ensure optimum performance from installed cards when the chassis is connected to a Thunderbolt 2-equipped computer. Need to connect to a computer equipped with 10Gbps Thunderbolt? No problem, the Echo Express III-R is fully compatible with earlier generation Thunderbolt computers as well.
