In the age of mobile content creation, iPhone users increasingly rely on magnetic external SSDs to overcome internal storage limits and to record high-quality video formats like ProRes directly to external media. A well-designed magnetic SSD adheres to the back of the iPhone (or via a MagSafe adapter), giving you fast, convenient, and compact external storage. Below, we compare three excellent magnetic external SSDs for iPhone use—Orico K20, TeamGroup PD20M, and Yottamaster—and help you decide which one fits your needs.
1. Orico K20 SSD
The Orico K20 (or K20 Mini variant) features a slim aluminum body and claims transfer speeds up to 2000 MB/s. Attach your phone securely with magnetic adsorption, ensuring it stays in place without slipping. The package also comes with a magnetic ring, allowing you to easily connect a wide range of devices. (Note: not compatible with Apple phones using a Lightning connector.)
Expand your storage instantly with this external solid-state drive—just plug and play to solve memory shortages in seconds, making the Orico portable SSD a perfect companion for photography lovers.
The Orico K20 also supports 4K 120 fps ProRes HDR video recording on iPhone 16 Pro and Pro Max, letting you save directly to the drive, edit straight from it, and skip the hassle of secondary transfers. In sum, the Orico K20 is a high-speed choice that complements the aesthetics and performance expectations of iPhone creators.
2. TeamGroup PD20M SSD
The TeamGroup PD20M is engineered to strike a balance between performance, magnetic strength, and usability. It uses a magnetic suction system designed to hold firmly even during movement, while maintaining a slim physical profile. The PD20M Portable SSD from Teamgroup is a dedicated storage solution designed with a magnetic force exceeding 800 g, ensuring a secure and reliable hold. Its one-touch metal magnetic attachment makes it adaptable to a wide range of scenarios. Combining performance with style, this magnetic SSD boasts a refined look with a slim 0.82 cm profile—thinner than an iPhone 15—and smooth, rounded edges for a comfortable feel. Its lightweight, compact build makes it effortless to carry anywhere, while transfer speeds of up to 20 Gbps deliver rapid, lag-free file sharing. Because of its design and performance, the PD20M is a dependable companion for creators who want strong magnetic adhesion without sacrificing speed or ease of integration with iPhone workflows.
3. Yottamaster Magnetic SSD
Yottamaster’s magnetic portable SSD line offers strong features at a more accessible price point. This portable SSD attaches directly to iPhones and MagSafe-compatible cases, and it also comes with a magnetic ring for secure connection to devices or cases without built-in magnets. Designed with mobile photographers in mind, it offers the perfect blend of portability and efficiency, letting you capture and store large collections of high-resolution photos and videos anytime, anywhere. Note: When using a phone case, it’s best to apply the included magnetic ring to ensure a stable hold and prevent accidental detachment. The magnetic SSD is available in 512GB, 1TB, and 2TB storage options, giving users the flexibility to choose based on their needs. Where the Yottamaster drive shines is in striking a balance between cost and performance. Although it may not be as extensively tested as some more established brands, it offers a compelling mix of magnetic design, speed, and affordability. For users who want good performance without stretching to premium pricing, it is a strong candidate.
