Sonnet Ships Quietest and Most Compact Thunderbolt™ 2-to-PCIe Expansion Chassis
Echo™ Express SEL Delivers Thunderbolt 2 for Low-Profile PCI Express® Cards
The Echo Express SEL incorporates ultra-fast Thunderbolt 2 technology, which delivers twice the bandwidth of Thunderbolt and provides sufficient throughput to support many of the highest-performing and most demanding PCIe cards. The new expansion chassis is ideally suited for use with high-bandwidth networking cards, host bus adapters, and storage interface cards, allowing them to connect with Thunderbolt-enabled iMac®, Mac mini, MacBook Air®, and MacBook Pro® computers, as well as Mac Pro® computers that lack PCIe expansion slots. Plus, the Echo Express SEL's dual Thunderbolt 2 ports not only support full-bandwidth connectivity with 20 Gb/sec Thunderbolt 2-equipped host computers, but provide full backward compatibility with 10 Gb/sec Thunderbolt-equipped computers and devices, and support daisy-chaining of other Thunderbolt 2 and Thunderbolt devices.
The Echo Express SEL supports low-profile, single-width PCIe 2.0 x8 cards. The majority of the most popular Thunderbolt-compatible 16Gb and 8Gb Fibre Channel, 10 Gigabit Ethernet, SAS and SATA host bus adapters, and RAID controller cards fall into this category, making the SEL a perfect match for users needing a discrete, quiet, and yet very fast PCIe chassis to connect one of these specialized interface cards to their computers. Thunderbolt 2 technology is essential for enabling many high-performance cards, such as 10 Gigabit Ethernet, to yield optimal performance over Thunderbolt. For example, in a test using Small Tree Communications' dual-port 10 Gigabit Ethernet CAT6 Network Adapter with the Echo Express SEL, performance increased by 40 percent compared to the same card tested in a standard 10 Gb/sec Thunderbolt-to-PCIe chassis. The list of compatible PCIe cards is available on Sonnet's website, and is continually expanding as more cards are tested and certified.
Measuring 4 inches wide by 8.4 inches long by 2.8 inches tall and weighing just 1.75 pounds, the Echo Express SEL is compact and lightweight, yet its rugged aluminum case provides great protection for the installed card. The SEL features an ultra-quiet, temperature-controlled fan to help keep even warm cards cool. When not needed, the fan slows down to a whisper. The SEL is Sonnet's quietest expansion chassis yet.
The Echo Express SEL ships with an 80W external power adapter, keeping the system's energy usage low. The SEL also conserves energy by automatically powering on whenever the connected computer powers on or wakes, or powering off when the computer powers off or sleeps. Sonnet includes a cable locking mechanism that secures the Thunderbolt connectors and prevents accidental cable disconnects. Like the other models in the Echo Express family, the Echo Express SEL was designed, engineered, and built by Sonnet in California.
"Many of our customers that have only one PCIe card, such as a high-speed 10 Gigabit Ethernet, Fibre Channel, or high bandwidth storage interface card, need the increased performance of Thunderbolt 2 but want the smallest and quietest chassis possible," said Robert Farnsworth, CEO of Sonnet Technologies. "Now, users purchasing a new Mac Pro, or other Thunderbolt 2 technology-enabled computers, will be able to take advantage of the groundbreaking performance of Thunderbolt 2 technology using Sonnet's most affordable Thunderbolt 2-to-PCIe card expansion chassis."
The Echo Express SEL (part number ECHO-EXP-SEL) is now available for $399 USD. More information on the product and compatible PCIe expansion cards is available at www.sonnettech.com/product/echoexpresssel.html.
