For just $413.30, below its 30-day average of $538.04. This price undercuts the 90-day average of $476.26 and even beats the 180-day average of $442.84, making it one of the better pricing opportunities for this magnetic SSD since its release.

What You're Getting

The Oyen Digital Helix Mag40 delivers 4TB of high-speed storage with USB4 connectivity reaching up to 2800MB/s transfer speeds. Its magnetic attachment system snaps securely to MagSafe-enabled iPhones, providing reliable connectivity for mobile workflows. The aluminum housing offers durability while maintaining a slim profile that fits easily in pockets. This drive enables direct 4K ProRes video capture from compatible iPhones, bypassing internal storage limits for extended shooting sessions.

It uses TLC NAND flash for consistent performance and data integrity during demanding creative tasks.

Who This Is For

Best for iPhone 15 and newer users who regularly shoot high-bitrate video and need to offload footage quickly. Content creators working with 4K ProRes or similar formats will appreciate the direct-to-SSD recording capability.

Photographers and videographers who want to keep their workflow mobile without sacrificing storage capacity should consider this drive. Anyone who can wait for deeper discounts during major sales events might want to hold off, but this current price offers solid value for immediate needs.

The Caveat

This drive requires MagSafe compatibility, so iPhone 14 and older users will need a MagSafe case or adapter for proper magnetic attachment. While the USB4 interface offers excellent speed, you'll need compatible hardware to achieve the maximum 2800MB/s transfer rates.

Final Verdict

At $413.30, the Oyen Digital Helix Mag40 delivers substantial storage with professional-grade features at a price that beats recent averages. If you're regularly hitting storage limits while shooting 4K video on your iPhone, this magnetic SSD solves that problem while keeping your workflow streamlined. The current discount makes it worth considering now rather than waiting for uncertain future sales.
