High-intensity isn’t just a marketing term.
These drives are built for real production environments. Long takes, large files, continuous writes, and deadlines that don’t pause for thermal throttling. When you’re dumping cards on set, backing up a full day of footage, or working directly off an external drive, performance isn’t about a momentary burst. It’s about whether your SSD can maintain speed hour after hour, terabyte after terabyte. That’s what we mean by high-intensity SSDs: sustained performance under sustained pressure.
