Sonnet Presto SFP28 10Gb Ethernet 2-Port PCIe Card (SFP28 sold separately) (G10E-SFP-2XM-E3)

With increasing demands for greater data transfer speeds and more bandwidth over shared networks, and with specialized applications such as HD video editing using high-performance shared storage systems, the deployment of 10 Gigabit Ethernet networking has skyrocketed. This high-speed wired networking standard offers ten times the performance of Gigabit Ethernet, the most common wired network connection included with most computers today, and yet, most computers aren't equipped to get you connected. If you have a computer with a Thunderbolt port, Sonnet has a simple solution - the Twin 10G. This Thunderbolt-certified for Mac and Windows, 10GBase-T adapter is a powerful and cost-effective way to add 10 GbE connectivity to your setup.

The Twin 10G is a striking example of form following function - this adapter's attractive and rugged aluminum housing is engineered to effectively dissipate heat. Together with a temperature-tuned, ultra-quiet fan to quietly cool the components inside, this design enables the Twin 10G to be used comfortably in noise-sensitive environments.

The Twin 10G is easy to set up. To keep things simple, you configure its settings through the OS X Network control panel or Windows Device Manager. When you configure the device, you can also activate its advanced features: link aggregation of its two 10 GbE ports increases throughput beyond what a single connection can sustain; transparent failover between 10 GbE ports keeps your computer connected in case a single cable is disconnected or one of the ports fails, jumbo packet support can increase throughput and reduce CPU utilization; and Wake-on-LAN support enables remotely waking your computer when you need it, and not wasting energy when you don't.
