Our Take

Best for: Professional videographers and iPhone users needing fast, magnetic external storage.

The Oyen Digital Helix Mag40 is a purpose-built portable SSD for videographers and content creators. Its MagSafe magnetic attachment lets you snap it onto an iPhone 15 or later for offloading or direct 4K ProRes recording, bypassing internal storage limits. Inside, the USB4 interface delivers up to 2800MB/s reads and writes, keeping transfers fast. The slim aluminum housing is durable and pocket-friendly, but it lacks any water or dust protection, so it's best for desk or studio use. 12, it's priced at a premium over standard 4TB SSDs, but the unique magnetic integration and speed justify the cost for iPhone-heavy workflows. If you need a fast, magnetic external drive for professional video work, this is a solid choice.

Price Analysis

The current price of $623.12 is 12% off the original $711.49. While it matches the 90-day average, it's about $93 above the 180-day average of $529.68, suggesting the price has risen recently. If you don't need it immediately, waiting for a return to the lower price could save you money.
