Portable 512 GB USB 3.1 SSD

The WD My Passport SSD is a pocket-sized external drive that delivers up to 540 MB/s reads over USB 3.1 Gen 2. It connects with a USB Type-C cable and includes a Type-A adapter for broad host compatibility. Password protection with hardware encryption and WD Discovery software handle backup and security.

Travellers and creators needing fast.

Bus-powered operation and a rugged metal chassis suit mobile workflows where speed and data protection matter. The single USB-C port means no separate power brick, but users who require multiple simultaneous connections or legacy USB 2.0-only performance will find the feature set limited.

540 MB/s read speed over USB 3.1 Gen 2

That figure is the headline transfer rate and decides whether the drive matches the workload; it is achieved through the supplied USB Type-C to Type-C cable on hosts that support USB 3.1 Gen 2.

Questions about this item

Will the 512 GB flash memory need replacement after a certain number of write cycles?

The drive uses solid-state storage with no moving parts, so no mechanical maintenance is required; the controller manages wear internally and the product carries a 3-year limited warranty.

What limits sustained transfer speed during long copy jobs?

The USB 3.1 Gen 2 interface caps throughput at 10 Gb/s, and the controller throttles to stay within the 5 °C to 35 °C operating range, so thermal limits appear before the flash does.

How much noise and heat does the drive produce when running all day?

With no fan or spinning platters the drive is silent; the metal case dissipates heat passively and stays within the 5 °C to 35 °C operating window during continuous use.
