The OYEN DIGITAL Helix MAG40 combines high-speed portable storage with a compact magnetic design made for mobile creative workflows. Its MagSafe-compatible enclosure attaches securely to compatible iPhones, keeping up to 4TB of external storage close at hand while recording video, capturing photos, or transferring large projects.
A USB4 40Gb/s connection delivers speeds up to 2,800 MB/s, while the solid aluminum enclosure helps protect the SSD and dissipate heat without a fan. The Helix MAG40 can record supported 4K ProRes formats directly from compatible iPhones, helping preserve the phone’s internal storage during extended shoots.
It also works as a compact portable SSD for USB-C and Thunderbolt-equipped Mac and Windows computers.
