Portable Magnetic SSDs for iPhone Videography

The introduction of ProRes video recording on the iPhone 15 Pro and newer models has transformed mobile video production. However, it also presents a challenge for users: the massive file sizes can fill up internal storage in no time. Recording directly to an external drive is the logical solution. A magnetic external SSD offers a particularly elegant and stable solution for mobile workflows.

This article serves as a guide. It explains the key criteria for selecting a suitable external SSD and presents various models tailored for different use cases—from professional ProRes video recording to rapid data backups for power users.

What to Look for When Buying an External SSD

Choosing the right external storage depends on technical specifications that must align with your individual needs. Here are three key points that should influence your decision.

1. Transfer Speed and Interface

Speed is crucial, especially when working with large files. Pay attention to the USB interface:

• USB 3.2 Gen 2 offers speeds of up to 10 Gbps (approx. 1,050 MB/s). This is sufficient for most use cases, including 4K ProRes recording.
• A USB 3.2 Gen 2x2 SSD can reach theoretical speeds of up to 20 Gbps (approx. 2,000 MB/s). To leverage this speed, both the SSD and the host device (e.g., a PC or laptop) must support this standard. For the iPhone 15 Pro, whose port is limited to 10 Gbps, such an SSD offers no speed advantage, but it can unleash its full potential when connected to a compatible computer.

2. Compatibility and Form Factor

Ensure the SSD is compatible with your devices. For use as external storage for iPhone 15 series models and later, a USB-C connection is mandatory. A magnetic attachment compatible with the iPhone's MagSafe system ensures a secure hold without any extra mounts—ideal for filming on the move. Also, check if the SSD works with other devices like laptops, tablets, or gaming consoles (e.g., PS5) to maximize its versatility.

3. Capacity and Durability

ProRes files are very large. One minute of 4K video at 60 fps can consume several gigabytes of storage. A fast 1TB portable SSD is therefore a good starting point for regular video projects. For professional users, 2TB or more may also be a worthwhile investment. Since mobile SSDs are often used on the go, a durable build, shock resistance, and low weight are important features for longevity and data protection.

Storage Recommendations for Shoppers

Based on the criteria mentioned, we have compiled a selection of products that cover different needs.

Western Digital My Passport 1TB Black

Why It Stands Out This model is a classic mechanical hard drive (HDD), not an SSD. It is listed here as an alternative for use cases where storage capacity for the price is the priority, rather than maximum speed.

Pros:

• High storage capacity at a lower price-per-terabyte compared to SSDs.
• Proven technology that is well-suited for long-term archiving and backups.
• Simple plug-and-play operation via its USB 3.0 interface.
• Compact and lightweight body for a portable HDD.

Frequently Asked Questions (FAQ)

Can I record ProRes video on the iPhone 15 Pro with any external SSD?

No, not every SSD is suitable. Recording ProRes video requires a consistently high write speed. The iPhone tests the drive's performance before recording. As a rule, you need an SSD with a sustained write speed of at least 220 MB/s and a USB-C cable that supports data rates of at least 10 Gbps.

What is the difference between a magnetic SSD and a regular portable SSD?

Technologically, both are based on the same flash memory. However, a magnetic external SSD has built-in magnets compatible with the iPhone's MagSafe system. This allows it to attach directly to the back of the device, creating a very stable and cable-friendly setup for mobile filming.

Do I need a USB 3.2 Gen 2x2 SSD?

That depends on your devices. To achieve the maximum speed of a Gen 2x2 SSD (up to 20 Gbps), both the SSD and your computer must support the USB 3.2 Gen 2x2 standard. While a Gen 2x2 SSD will work with an iPhone 15 Pro, its speed will be throttled to the iPhone's 10 Gbps (USB 3.2 Gen 2) limit. However, it can be a future-proof investment if you also plan to use it with a compatible PC.
