TB3ESATU31 Thunderbolt 3 to eSTA Adapter

This Thunderbolt™ 3 to eSATA and USB 3.1 adapter lets you expand the connectivity of your Mac or PC laptop, by adding two essential ports. Simply connect it to the Thunderbolt 3 port on your laptop to provide an eSATA port and a USB 3.1 (10Gbps) port. Compact and portable, it’s the perfect companion for your MacBook Pro or any other Thunderbolt 3 equipped laptop.

Connect to your existing eSATA devices

Extend the life of your external storage devices. Using the adapter's eSATA port, simply connect an eSATA-equipped external hard drive, solid-state drive or external enclosure.

Connect to USB 3.1 (10Gbps) devices

The adapter lets you add any USB 3.1 or USB 3.0 device, such as an external hard drive, SSD or flash drive. It’s also backward compatible with USB 2.0 devices.

Fast, reliable performance

Leverage your Thunderbolt 3 port to create a high-speed solution that offers both eSATA and USB 3.1 connectivity. To maximize performance efficiency, two dedicated lanes connect the Thunderbolt adapter directly to your system PCIe bus. Both ports on the adapter deliver full bandwidth, so you avoid performance bottlenecks when the two ports are in use.

Rugged portability

Its compact and durable housing makes the adapter ideal for portable use. It requires no external power, and features an integrated Thunderbolt cable. Setting the adapter up is easy, with plug-and-play installation.

The TB3ESATU31 is backed by a 2-year warranty and free lifetime technical support.

Can I use a solid state drive (SSD) with this hard drive duplicator?

Solid-state drives (SSDs) use SATA connectors to access power and transfer data. Any duplicator that can copy to or from SATA hard drives will work with a duplicator. Note: If you use a dock to duplicate SSDs, keep in mind that the disk duplicators execute a sector by sector read and write. SSDs are rated by a number of reads and writes. Repeated duplication and sector by sector reads and writes of SSDs can reduce the life cycle of the drive.
