ProRes Challenges
Typically, users connect the external SSD to the iPhone with the included USB-C cable for the ProRes setup. However, following challenges will be encountered:
1. 10Gbps Data Rate: iPhone 15 Pro requires 10Gbps speed write to the external SSD. The included USB-C cable only supports USB 2.0 speed at 480Mbps, which is less than 5% of the 10Gbps bandwidth that ProRes recording needs. Thus users will experience lags in video recording and risks of data corruption.
2. Limited Battery Power: ProRes video shooting can quickly drain the iPhone’s battery, particularly when the SSD also needs to be powered by the iPhone. Some 2TB SSDs can’t even be powered by an iPhone directly since its power consumption exceeds what an iPhone can supply.
3. No Expandability: ProRes users may desire more USB peripheral connections in their setup — for example, a USB microphone for better audio recording or multiple SSDs. However, iPhone 15 Pro only comes with one single USB-C port.
