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.

Increased Thermal Ceiling

Solid aluminum core and outer shell allow Atom EX to remove significantly more heat from the internal components. Allowing for higher sustained speeds and increased reliability.

Rugged and Travel Safe

Designed to endure the elements with MIL-Standard 810F rating for shock, vibration, and dust resistance. Aluminum exo-skeleton with soft composite bumper keeps your files secure and surrounding gear safe.

Comprehensive Warranty

Every Glyph drive comes with our industry leading 3-2-1 warranty. Three years of full hardware coverage, including the cables. Two years of Level-1 data recovery, and one year of advanced replacement.

Production-Grade Storage

Glyph has been in the storage game for over 32 years and trusted by creative professionals around the globe. Whether you are a filmmaker, photographer, or aspiring music producer, you can trust Glyph when it matters most.

The Atom EX40 High-Intensity USB4 NVMe SSD takes portable performance to the next level with USB4 speeds up to 4,000 MB/s,

Most SSDs aren’t designed for this kind of work.. but their spec sheets won't admit it.

Nearly every drive on the market is advertised using peak speeds measured in short, idealized bursts. In real workflows, those speeds collapse once caches fill and heat builds. The result: transfer times that stretch unpredictably and slowdowns you can feel in the middle of a job. We design our drives around sustained throughput, not headline numbers. The chart below illustrates what we're talking about.

How Long to Write 1TB of Media?

We compared Atom EX40 to the fastest available portable SSDs from other manufacturers and asked a simple question. How much time to write 1TB of media? (Test machine: TB5 equipped Mac Studio, M4 Max/4TB SSD/128GB RAM)
