Learn More About Portable SSDs

Enclosure: The SSD module is protected inside a compact enclosure designed to withstand travel, including certain levels of water, drop, and dust resistance.

SSD Module: The heart of the portable SSD is the SSD module, which contains the NAND flash memory where data is stored, and a controller that manages data operations.

Data Transfer Ports: The portable SSD connects to your host device, such as a laptop, via ports designed for USB or Thunderbolt protocols — or occasionally both.

Power Delivery: Unlike larger external SSDs, portable SSDs typically draw power over their data connection, which eliminates the need for a separate power source.
