Boasting a new black exterior, and featuring 20Gbps Thunderbolt 2 technology that provides sufficient bandwidth to support many of the highest performance and most demanding PCIe cards, Sonnet's Echo Express SEL delivers maximum performance when connected to a computer with Thunderbolt 2. The SEL is also fully compatible with computers with 10Gbps Thunderbolt technology, supporting most cards at full-performance. The Echo Express SEL is small, light, and perfect for use in situations where only a single low-profile PCIe card is needed. Measuring a scant 4" wide by 8.4" long by 2.8" tall, the SEL was designed specifically to house one low-profile PCIe card. Many of the most popular Thunderbolt-compatible high-speed networking and storage controller cards are a perfect fit. The SEL's small size doesn't limit its performance; installed in this system, a card will perform the same as when installed in an Echo Express SE II, Echo Express III-D, or Echo Express III-R. And like the other Echo Express models, the SEL includes two Thunderbolt ports to support daisy chaining of up to six devices from a single port on your computer.
