Sonnet Launches Thunderbolt 3-to-PCI Express Card Expansion Systems

Single-slot Echo Express SEL and Echo Express SE I Chassis now enable up to 2.75 GB/s data transfers for computers with thunderbolt 3. They enable the use of a wide variety of high-performance PCI Express (PCIe) cards with computers equipped with Thunderbolt ports. Both the SEL and SE I are compact and lightweight single-slot Thunderbolt 3 expansion systems, differing only in size, that are ideal where users only need to connect a single PCIe card.

With the new interface, both systems enable users of computers equipped with 40Gb/s Thunderbolt 3 (USB-C) ports, such as the new MacBook Pro, to take advantage of Thunderbolt 3's 2.75 GB/s of PCI Express bandwidth to support the most demanding, highest performance adapter cards. Sonnet is also making available Thunderbolt 3 upgrade cards for existing Thunderbolt 2 Echo Express SEL and SE I expansion systems, enabling those models with all the capabilities of the new Thunderbolt 3 Editions.

The Echo Express SE I — Thunderbolt 3 Edition accommodates one-half length, full-height, single-width PCIe 3.0 cards with additional mounting space for a daughter card. With its Thunderbolt 3 interface, the SE I delivers ample bandwidth for the majority of Thunderbolt-compatible PCIe cards including pro video capture, digital audio interface, 6Gbps or 12Gbps SAS or SATA host bus adapters, 16Gb or 8Gb Fibre Channel, 10 Gigabit Ethernet, and RAID controller PCIe cards.

The Echo Express SEL — Thunderbolt 3 Edition is the smallest and quietest Thunderbolt 3 chassis. The SEL houses one low-profile, single-width PCIe 3.0 card, including the majority of the most popular Thunderbolt-compatible 16Gb and 8Gb Fibre Channel, 40 and 10 Gigabit Ethernet, 6Gbps or 12Gbps SAS and SATA host bus adapters, RAID controller cards, and even low-profile pro video capture cards like the BlueFish 444 Epoch 4K Neutron.

The Echo Express SE I and Echo Express SEL Thunderbolt 3 Editions feature dual 40Gb/s Thunderbolt 3 ports that support the daisy chaining of up to five additional Thunderbolt peripheral devices. Both models support backward compatibility for 20Gb/s Thunderbolt 2- and 10Gbps Thunderbolt-equipped devices when connected via the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter.

As an added benefit, the second Thunderbolt 3 port also supports a variety of displays and a multitude of USB 3.1, USB 3.0, and USB 2.0 devices when connected with the proper cable, and also fully support the DisplayPort 1.2 protocol, which enables streaming to one 4K display at 120Hz, or two 4K displays at 60Hz, or one 5K display at 60Hz.
