Add Fast 6Gb/s eSATA and SuperSpeed USB 3.0 Connectivity to Your Computer With One Adapter

Do you need to connect high-speed USB 3.0 and eSATA devices to your computer? Sonnet’s USB 3.0+eSATA Thunderbolt Adapter provides you a simple, economical way to simultaneously connect one USB 3.0 device plus one eSATA drive or card reader to any Mac® with a Thunderbolt 2 or Thunderbolt port, or Windows® computer with Thunderbolt 2 ports. Featuring 10Gbps Thunderbolt technology, this compact adapter connects directly to your computer or at the end of a Thunderbolt device chain with its built-in Thunderbolt cable to enable fast data transfers between your drives and computer.

USB 3.0 for Fast Performance and Common Connectivity

USB 3.0 Performance IconMost drives available today include USB 3.0 interfaces. Although you can connect them to the USB 2.0 ports on your computer, their performance would be reduced by as much as 85 percent! This useful adapter offers native USB 3.0 support to ensure great performance from the fast drives you connect, enabling data transfers at up to 350 MB/s. The USB 3.0 + Gigabit Ethernet Thunderbolt Adapter supports UASP (USB Attached SCSI Protocol) support, ensuring that UASP-enabled external drives connected to the adapter achieve their maximum data transfer rate potential, with performance improved by up to 20% above the drive connected to a USB host without UASP support. Need to connect more than one drive? The adapter works with multi-drive enclosures(1) with hardware raid controllers, too. This adapter also supports hubs and other USB 3.0 devices, and is backward compatible with USB 2.0 devices(2). If your computer already has USB 3.0 onboard, this adapter provides another handy port.

eSATA for Extra Speed

eSATA & SSDs Arrows IconSonnet’s USB 3.0+eSATA Thunderbolt Adapter is well suited to handle the increased bandwidth requirements of 6Gb/s SSDs through its fast eSATA interface. Capable of transferring files at up to 375 MB/s, this Thunderbolt adapter also supports the latest multi-drive enclosures with hardware raid controllers, and older ones with port multipliers, enabling you to access up to five drives(1) through one eSATA cable. The eSATA port allows you to boot from an attached drive under OS X®, and offers support for media readers with eSATA interfaces such as the RED STATION REDMAG 1.8" and 2.5". 

Simple to Set Up, Simple to Use

Thunderbolt Cable IconWhen used with a Mac computer, the USB 3.0+eSATA Thunderbolt Adapter requires no setup—the necessary drivers are already installed—just plug it into your computer and it works. When connected to a Windows PC, a simple driver download and installation is all that’s required to get you going.

Bus Powered IconThis device is bus-powered, so there’s no need to connect an AC power adapter, making it perfect for use anywhere. Wherever you use it, the Sonnet USB 3.0+eSATA Thunderbolt Adapter is a simple and cost-effective solution that enables you to simultaneously connect your USB 3.0 and eSATA peripherals without hassle.

Technical Notes

  1. Support for up to four drives requires the use of drive enclosures employing a hardware RAID controller (like Sonnet’s Fusion™ QR). Support for up to five drives requires the use of drive enclosures equipped with eSATA ports and port multipliers.
  2. USB 3.0 devices require USB 3.0 cables to support USB 3.0 (SuperSpeed) transfer speeds (up to 5 Gb/s). Use of USB 2.0 cables between USB 3.0 devices and the USB 3.0+eSATA Thunderbolt Adapter is supported, but data transfers are limited to USB 2.0 speeds (up to 480 Mb/s).
  3. Supports booting from an attached drive with any Thunderbolt Mac running OS X 10.8.5+.
