The S252SMTB3 2-bay Thunderbolt enclosure enables you to connect two 2.5" SATA I/II/III hard drives (HDD) or solid state drives (SSD) to your Mac® or PC using an available Thunderbolt port.

Faster Transfer Speeds

Transfer data to and from your external drives faster than ever before, through a Thunderbolt connection. With data transfer speeds up to 10 Gbps, Thunderbolt performs 100% faster than USB 3.0 (5 Gbps), and 60% faster than eSATA (6Gbps). The unprecedented performance Thunderbolt offers makes this enclosure an ideal solution for high-resolution video editing and photography applications.

Connect Right out of the Box

To save you time and money, the S252SMTB3 includes a high-quality 1m Thunderbolt cable, ensuring you have everything you need for a hassle-free installation.

Excellent Drive Protection

To help ensure optimal operating temperatures for your hard drives and solid state drives, the Thunderbolt enclosure features a built-in fan and a durable, solid aluminum housing that maximizes heat dissipation.

Daisy Chain for Added Flexibility and Scalability

Get the most out of your Thunderbolt devices by leveraging the Thunderbolt daisy chain port. You can connect up to 6 additional devices such as monitors, docking stations, or additional external drives. This is an excellent docking storage solution for Ultrabooks or smaller more portable laptops that have fewer I/O ports.

The S25SMTB3 is backed by a 2-year warranty and free lifetime technical support.

  • Seamless performance from external drives, through a 10Gbps Thunderbolt host connection
  • Excellent drive protection and heat dissipation with durable aluminum housing and built-in fan
  • Connect right out of the box, with high quality 1m Thunderbolt cable included
