Yes, this external SSD is normally usable with Windows as well as Linux (Ubuntu). This is a portable SSD with a USB-C interface, compatible with systems that support this type of connection. For optimum use, you may need to format the SSD in a file system compatible with both systems, such as exFAT, which is recognised by both Windows and Linux without complex manipulation. No specific driver installation is generally required, as modern systems handle external USB SSDs natively. However, if the SSD has been formatted in a proprietary format or with protections (encryption), it may be necessary to reformat or adjust the permissions to ensure full compatibility.
