The Sony PSZ-HC Series Rugged USB 3.0 External Hard Drive is a portable and durable drive built with a tough silicon housing designed to withstand the wear and tear of everyday use. It has a 1TB storage capacity and features both USB 3.0 Type-A and Type-C interfaces for compatibility with a wide range of devices. The USB Type-A cable is built-in for your convenience and can be stored within the drive when not needed. For a Type-C connection, you will have to use your own cable. After connecting the drive, you'll be able to transfer data quickly at speeds of up to 138 MB/s. Moreover, it's preformatted as exFAT, which allows you to use it with both Windows and Mac systems. To help you manage your data, Sony's Memory Media Utility Software is pre-installed on the drive."
