Dual USB drive for creative professionals

The SanDisk Extreme PRO Dual 512GB flash drive provides a USB Type-A and a USB Type-C connector on a single metal body. Sequential reads reach up to 1,000MB/s and writes up to 900MB/s over USB 3.2 Gen 2. Hardware-based 256kb Blowfish-level encryption protects stored files. The drive weighs 0.05 pounds and is offered in black.

Check your host ports and operating system

Verify that your computer, tablet or Android phone exposes either a USB Type-A or USB Type-C port that supports USB 3.2 Gen 2 signalling to achieve the advertised throughput. Older ports will fall back to slower speeds. The SanDisk Memory Zone app enables automatic backup and file organisation on compatible Android devices; confirm the app installs on your OS version before relying on it.

Thermals noise and power in typical use

The solid-state design has no moving parts, so the drive runs silently during transfers. Under sustained read or write loads the metal casing may become warm to the touch, which is normal for high-speed flash storage. Power is drawn entirely from the host USB port; no external supply is required. The 512GB capacity offers ample space for active projects without needing multiple drives.

Questions about this item

Does the box include any cables or adapters, or do I need to buy a USB Type-C to Type-A cable separately?

The drive has both a USB Type-A and a USB Type-C connector built in, so no separate cable or adapter is required for either port.

I see the drive is rated for up to 1,000MB/s read and 900MB/s write; which capacity should I choose for video editing?

This model is the 512GB version; the Extreme PRO Dual series also offers larger capacities up to 2TB if you need more space for large video files.

The listing says up to 1,000MB/s read over USB 3.2 Gen 2; what speed will I actually see on my laptop?

Real-world speeds depend on your device's USB port performance and file types, but the drive supports up to 1,000MB/s read and 900MB/s write on a compatible USB 3.2 Gen 2 port.
