Wise Advanced has announced the i4 Mobile SSD, a compact external storage device designed with Apple users in mind. It’s about the size of the palm of your hand, and features MagSafe compatibility, along with data transfer rates up to 4000 MB/s, and a sustained write speed of at least 650 MB/s. Let’s have a look!
Wise Advanced, founded in 1992 and based in Taipei, Taiwan, develops high-speed storage media designed for professional photo and video workflows. Their lineup includes CFexpress Type A and B cards, SDXC memory cards, solid-state drives, and card readers. The i4 Mobile SSD for iPhones is the latest in their mobile lineup.
The i4 Mobile SSD delivers very fast read speeds up to 4000 MB/s and write speeds up to 3500 MB/s, with a minimum sustained write speed of 650 MB/s. That makes it fast enough to record high-resolution video directly to external storage on supported iPhones, including 4K ProRes at 120 fps on the iPhone 16 Pro and Pro Max (only certain iPhone models support recording ProRes directly on an external storage device connected with USB-C. For specific models, please see the link here.)
The i4 uses a built-in MagSafe-compatible ring to attach to the phone (does not offer charging functionality).
The device is powered by a “next-generation low-power-consumption chip,” which the company says is integrated into the i4 Mobile SSD, allowing it to operate without active cooling or an external power supply. It’s powered via USB-C and comes with two cables: a 50 cm (19.68 in) USB4 cable that’s USB-IF certified, and a shorter, more flexible 10 cm (3.93 in) option.
Other options you can consider when comparing fast, external mobile devices for your iPhone are Angelbird’s Kondor Blue, which attaches via MagSafe and records onto a professional CFexpress Type B card in up to 4K ProRes 120 fps, or Corsair EX400U, which also has MagSafe and is compatible with other USB-C host devices. It is available in 1TB, 2TB, and 4TB.
We don’t have a price on the Wise i4 Mobile SSD yet, but the expected release date is sometime in mid-June. For more information, please see the Wise Advanced website here.

A camera was put in my hands at 16, and I’ve been taking photographs ever since. Before moving to Vienna, I worked as a photographer on film sets, telling stories as they unfolded behind the scenes. Since then, I’ve focused on immersive theater, both as a photographer and an actor. I am the photographer for the award-winning Nesterval ensemble, documenting the energy and atmosphere of their performances. I’m a teller of stories. Stories hold my interest. I’ll take on any project with a story to tell.
