Recording 4K ProRes HDR video on your iPhone 15 Pro or 16 Pro is a game-changer for creators. However, if you’ve ever tried filming a long take directly to an external drive, you’ve likely encountered the "ProRes Nightmare": dropped frames, stuttering playback, or even corrupted files that refuse to open.
The culprit? It’s usually a combination of thermal throttling and unstable write speeds. Most portable SSDs and flash drives run "blind"—you have no idea how hot they are getting or if the speed is dipping until it's too late.
The Hidden Trap of 4K ProRes Recording
When recording 4K at 60fps or 120fps, your iPhone pushes massive amounts of data (up to 6GB per minute) through the USB-C port. This process generates significant heat in both the phone and the connected drive.
- The Overheating Slowdown: Most high-speed drives throttle their speed once they hit a certain temperature to protect the hardware. If the speed drops below the required bitrate for ProRes, your recording will glitch or stop entirely.
- The "Blind" Transfer: With standard drives, you can't tell if the connection is secure or if the drive is overheating until you check the footage later and find it ruined.
Meet MOVESPEED SeeU SU10: The World’s First Smart Display SSD Drive
The MOVESPEED SeeU SU10 isn't just another flash drive; it’s a professional-grade monitoring tool designed to solve the anxiety of high-end mobile cinematography.
1. See Everything, Instantly
The standout feature is the Built-in Smart Display. For the first time, you can monitor your drive's status in real-time without extra apps:
- Real-time Temperature: Know exactly when the drive is working hard. The SU10 performs best below 65°C, and the screen lets you know when to give it a quick break to ensure data integrity.
- Live Speed Monitoring: Confirm you are hitting those 1090 MB/s speeds required for smooth 4K 60fps/120fps recording.
- Capacity Alerts: Never run out of space mid-scene. The display shows remaining storage so you can swap drives before the "Storage Full" error ruins your take.
2. Professional-Grade Stability (Up to 1090 MB/s)
While many drives claim high speeds, they often "dip" after a few minutes. The SeeU SU10 uses SSD-grade components to maintain sustained high-speed performance. This stability is the difference between a perfect cinematic shot and a corrupted file.
3. Dual Interface for a Seamless Workflow
With both USB-C and USB-A ports, you can record on your iPhone and instantly plug it into your MacBook or PC for editing. No dongles, no cables, no hassle.
Built for the Real World
The SeeU SU10 is encased in a full metal zinc-alloy body, providing superior heat dissipation and durability.
