2TB Portable USB-C SSD

The Corsair EX100U is a 2TB portable solid-state drive built around a USB 3.2 Gen 2x2 interface. Sequential reads reach 1600 MB/s and writes reach 1500 MB/s. A gunmetal plastic heatsink manages thermals during sustained transfers. Both USB-C to C and USB-C to A cables are included for broad device compatibility.

For mobile professionals needing fast external

This drive suits users who move large media libraries between laptops, desktops and tablets with USB-C or USB-A ports. The 2TB capacity holds extensive project files. Buyers who require hardware encryption or ruggedised IP-rated housing should consider alternatives, as those features are not present on this model.

USB 3.2 Gen 2x2 interface decides the speed ceiling

Peak throughput of 1600 MB/s read and 1500 MB/s write is only available when the host port supports USB 3.2 Gen 2x2 operation. On older USB 3.2 Gen 2 or USB 3.0 ports the drive will negotiate lower speeds. Verify your device specification before purchase to ensure the performance matches your workflow.
