Advanced Video Recording Features on the Latest iPhone Models
Starting with the iPhone 15 Pro, Apple’s high-end iPhone models have been capable of recording in 4K ProRes at 60 fps. This high-quality video format generates very large file sizes, prompting Apple to restrict recordings to external SSDs only—a 1-hour and 12-minute video in this format can take up approximately 1 TB of storage. Despite launching its first 2 TB iPhone model this year, Apple has not lifted these restrictions for internal recording capabilities.

Challenges with ProRes RAW and ProRes RAW HQ Formats
The ProRes RAW and ProRes RAW HQ video formats are also extremely storage-intensive. A 1 TB SSD cannot even sustain 60 minutes of recording in these formats. However, with the introduction of a 2 TB storage option in the iPhone 17 Pro Max, videographers might have been excited about the potential to utilize such ample internal storage. Unfortunately, this model does not offer greater flexibility than its predecessors, as it is still not possible to record in ProRes 4K at 60 fps or in ProRes RAW and ProRes RAW HQ formats directly to the phone’s internal storage.
This software limitation seems somewhat illogical and frustrating. On the 2 TB iPhone 17 Pro Max that I am currently reviewing, I can record in ProRes RAW using a 1 TB external SSD, even though there is 1.8 TB of free space available on the phone’s internal storage. The issue is not related to the performance of the internal storage, which actually shows faster data transfer rates than a compatible SSD.
Has Apple forgotten that it sells 2 TB iPhones? There could be several reasons for maintaining this limitation: potential overheating issues, a limited SLC cache that reduces speeds after a certain threshold, or long-term wear and tear risks on the internal storage. It’s also possible that Apple might reconsider this decision in a future update. Until then, videographers looking to experiment with the new ProRes RAW and ProRes RAW HQ formats will need to rely on external SSDs.
