Echo 15+ Thunderbolt 2 Dock with Blu-ray Drive & Storage Bay

Mac / PC / Thunderbolt 2 / USB 3.0 / FireWire 800 / eSATA / RJ45 / 3.5mm
The Complete Thunderbolt Dock
Connect Your Peripherals with One Cable
Sonnet's Echo 15+ Thunderbolt™ 2 Dock enables you to connect any computer with a Thunderbolt port to your peripherals through a single Thunderbolt cable (sold separately). Simply plug in your printer, keyboard, mouse, cable modem, external hard drive, display, headphones, speakers, microphone, and iPad®, iPhone®, or iPod®, and other devices to the Echo dock with their supplied cables, and connect your computer to the dock with a Thunderbolt cable. When it's time to disconnect your computer, just unplug the Thunderbolt cable!
Versatile for Your Needs
The Echo 15+ Thunderbolt 2 Dock gives you plenty of interfaces to choose from, including USB 3.0, SATA and eSATA, FireWire 800, Gigabit Ethernet, 3.5 mm audio input, 3.5 mm audio output, and Thunderbolt 2. For your convenience, USB 3.0, audio input, and audio output ports are placed on both the front and back of the enclosure, so you can leave frequently used devices connected to the back, and devices you may need to disconnect more often, to the front.
Blu-ray Disc Player Included
If you've purchased a new computer lately, you may have noticed something's missing-an optical drive. Not to worry, the Echo 15+ Thunderbolt 2 Dock with Blu-ray Disc Player has you covered-it includes a Blu-ray BD-ROM/8x DVD±RW drive to load software, import CDs, burn CDs and DVD-ROMs, and play DVDs. The Echo 15+ Thunderbolt 2 Dock with Blu-ray Drive even includes software that enables Blu-ray movie playback on your Mac computer or attached display.
Space for Extra Drive Storage
Sonnet designed the Echo 15+ Thunderbolt 2 Dock with extra space, mounting hardware, and connectors for you to install one 3.5" SATA hard drive, or two 2.5" drives, either SSDs (solid state drives) or hard drives. Dual independent 6Gb/s SATA interfaces deliver maximum performance to support a pair of SSDs at up to 750MB/s, or an HDD at its maximum speeds. Add a high-capacity drive to use as your Mac's Time Machine drive, to back up your computer's data, or to store your ever-growing media library. Optionally, you can install a pair of high-performance SSDs for blazing-fast access to applications and files, or a pair of 2.5" hard drives mirrored for redundancy. Whichever choice you make, the drive or drives mount inside the Echo dock, so you can expand your storage without the fuss of adding another external drive enclosure, another power brick, and more cable clutter.
4K Workflow Support
The Echo 15+ is the perfect docking station for connecting all of your peripherals, including the latest ultra HD 4K displays. With all the ports necessary to connect current and legacy devices, the option to add internal storage with support for data transfer rates of up to 750 MB/s, as well as the ability to burn projects to optical media, Sonnet's Echo 15+ Thunderbolt 2 Dock becomes your go-to station for flexible connectivity.
Rugged Aluminum Design
Sonnet designed the Echo 15+ Thunderbolt 2 Dock for maximum flexibility in use. The rugged aluminum case is engineered to effectively dissipate heat and is more than sturdy enough to support the latest Mac Pro, a 27" all-in-one computer, or a large format display up to 34".
iPhone and iPad Charging Hub
With its four powered USB 3.0 ports, the Echo 15+ Thunderbolt 2 Dock will be the hub for charging devices, too. Each port can charge your iPad, iPhone, or iPod, even when your computer is disconnected, off, or sleeping.
