An external SSD provides virtually unlimited storage for these files, preventing your phone’s internal storage from filling up quickly and enabling extended recording sessions at the highest quality settings.
Q2: What is ProRes video and why does it need so much space?
A2: ProRes is a professional video codec developed by Apple that offers high fidelity and efficiency for video editing. It captures more visual information than standard video formats, resulting in larger file sizes but significantly better image quality and more flexibility in post-production.

* Speed: Aim for at least 1000MB/s read/write speeds for smooth 4K ProRes recording.

* Durability: IP ratings (dust/water resistance) and drop protection are great for on-the-go use.
* Special Features: Magnetic attachment (like DIGIERA) or specific Apple optimization (like Crucial X9 Pro for Mac) can enhance your experience.
Q4: How do I connect an external SSD to my iPhone 15 Pro Max?

Q6: Are all portable SSDs compatible with the iPhone 15 Pro Max?
A6: Most modern portable SSDs with a USB-C interface will be compatible.
