About Transcend ESD420C

The Transcend ESD420C 4TB is a cutting-edge portable SSD that redefines convenience for the modern mobile professional and creative. While many drives prioritize either speed or form factor, the ESD420C excels at both, introducing a unique magnetic attachment system. This allows the drive to snap securely onto the back of iPhones (with MagSafe) or laptops with the included magnetic ring, ensuring your storage is always physically attached to your device during high-stakes transfers.

Under the hood, the ESD420C is built for extreme efficiency. It utilizes the ultra-fast USB 3.2 Gen 2x2 interface, enabling it to reach blistering speeds of up to 2,000 MB/s read and 2,000 MB/s write. This 20Gbps throughput is double the speed of standard portable SSDs, making it a perfect match for ProRes video recording directly from a smartphone or moving massive 8K RAW files in a matter of seconds. It is designed to handle the most demanding workloads without breaking a sweat.

Despite its power, the ESD420C is incredibly compact. Its sleek, metallic finish is not just for show; the aluminum housing provides superior thermal management, preventing throttling during long file transfers. Key design highlights include:

Magnetic Mounting: Snaps directly to compatible smartphones and tablets for a cable-managed, handheld shooting experience.

Universal Connectivity: Includes a high-quality USB-C cable for seamless use with the latest PCs, Macs, and consoles.

High Capacity: The 4TB model provides ample room for thousands of high-resolution images or hours of cinematic footage.
