Magnetic Portable SSD for iPhone

The Transcend ESD420 is a 4TB external SSD that attaches magnetically to MagSafe-compatible iPhones. It connects via USB Type-C for plug-and-play operation without extra drivers. The lightweight, slim chassis makes it easy to carry for photographers and creators who need extra space while shooting on location.

Magnetic attachment expands mobile workflow

The built-in magnets let the drive snap directly onto a compatible iPhone or a magnetic case, keeping storage at hand during recording. This secure hold means the drive stays in place while you move, so backups and file transfers happen without cables dangling. If a device lacks native magnetic support, a magnetic-compatible case is required for proper attachment.

4TB capacity handles 4K ProRes and 8K media

Up to 4TB provides ample room for high-resolution video, raw photos and large project files during extended shoots. The 20Gbps USB interface keeps ingest speeds high enough for demanding 4K ProRes capture. Users who need more than 4TB or who work with devices that cannot use magnetic mounting will need a different storage solution.

Questions about this item

How often will the magnetic clip or adhesive surface need replacing?

The magnetic attachment relies on the built-in MagSafe-compatible array and a metal ring on the case; no adhesive is used, so there is no consumable surface to swap out.

What is the first bottleneck during a long 4K ProRes recording session?

Sustained write speed is limited by the integrated SLC cache size; once the cache fills, the drive drops to the native NAND rate.

Does the drive get hot or loud when it runs all day attached to an iPhone?

The aluminium shell acts as a passive heatsink and there are no moving parts, so it stays silent and only warm to the touch during continuous use.
