Top External SSDs for iPhone 15

With the introduction of the USB-C port on the iPhone 15, especially the Pro models, the door has opened for professional workflows. The ability to record high-resolution ProRes video directly to an external storage device is a game-changer for content creators and videographers. However, this feature also presents a challenge: the iPhone's internal storage fills up quickly.

An external SSD (Solid State Drive) is the logical solution. It not only provides much-needed storage expansion for the iPhone 15 Pro but also delivers the speed required for smooth recording and transfer of large files. This article serves as a guide to help you find the right external SSD for your needs. We'll introduce various models and explain the key criteria you should consider in your decision.

Buyer's Guide: What to Look for in an External SSD for the iPhone 15

Choosing the right storage device depends on your specific use case. Consider the following three points to make an informed decision.

1. Transfer Speed and Interface

For direct recording of 4K ProRes video at 60 fps on the iPhone 15 Pro, a consistent and high write speed is essential. Look for an external drive with USB-C and the USB 3.2 Gen 2 specification, which enables theoretical speeds of up to 10 Gbit/s (approx. 1,050 MB/s). For even more demanding workflows where large amounts of data need to be transferred quickly to a computer, an SSD with USB 3.2 Gen 2x2 (up to 20 Gbit/s) can be beneficial, provided your computer also supports this standard. A fast SSD for Mac and PC is crucial to avoid workflow bottlenecks.

2. Form Factor and Portability: Classic or Magnetic?

A portable SSD should be compact and durable. For users who film frequently on the go, a new category has emerged: the magnetic SSD. These drives attach directly to the back of the iPhone 15 Pro or Pro Max (often with a compatible case). This prevents the drive from dangling from the cable during recording, which significantly improves handling and reduces the risk of disconnections. Classic external SSDs without a magnetic feature are often slightly more affordable and are well-suited for stationary backups or data transfers at your desk.

3. Capacity and Compatibility

The file sizes of ProRes videos are substantial. A single minute of 4K ProRes at 30 fps can take up over 6 GB of space. A capacity of 1 TB is therefore a good starting point for regular video recording. Models like the Samsung T7 2TB offer a generous buffer for longer projects. Ensure the SSD is formatted with APFS or exFAT to guarantee compatibility with your iPhone and other devices like a Mac or Windows PC. Most modern SSDs come pre-formatted accordingly.

Frequently Asked Questions (FAQ)

Can you record directly to an external SSD with the iPhone 15?

Yes, the iPhone 15 Pro and iPhone 15 Pro Max models support direct video recording to an external SSD connected via the USB-C port. This is specifically intended for the storage-intensive ProRes format. The SSD must be formatted with the APFS or exFAT file system.

What speed does an SSD need for 4K ProRes video?

For recording 4K ProRes at 60 frames per second, a sustained write speed of at least 220 MB/s is required. Nearly all modern external SSDs connected via USB 3.1 Gen 2 or faster significantly exceed this requirement, providing enough of a buffer to prevent dropped frames.

Does every USB-C SSD work with the iPhone 15?

In theory, most external SSDs with a USB-C port and formatted with APFS or exFAT should work. In practice, however, some models may experience power delivery issues, especially those with a high power draw. It's advisable to choose a drive that is known to be compatible with the iPhone 15 or has its compatibility confirmed by the manufacturer.
