Glyph Capture+ CFexpress Type B 4.0 Memory Card 4TB

The Glyph Capture+ CFexpress Type B 4.0 Memory Card in 4TB is the flagship of the Capture+ lineup - built for productions with no room for compromise and no tolerance for downtime. It shares the same peak performance specs as the 2TB: read speeds up to 3,700 MB/s, write speeds up to 3,500 MB/s, and sustained write speeds of 3,000 MB/s. What it adds is sheer capacity - 4TB of fast, reliable, professional-grade storage on a card that fits in the palm of your hand. For extended shoots, multi-day productions, or workflows where switching cards is simply not an option, this is the card that changes the game.

SteadyIO technology is the constant across the entire Capture+ card family, and the 4TB is where it earns its keep most dramatically. Maintaining consistent read and write speeds across 4TB of storage under sustained load is a genuine engineering achievement. Whether you are capturing hours of uncompressed cinema-grade footage or shooting rapid-fire RAW stills in bursts, SteadyIO keeps the data pipeline moving without stutters, slowdowns, or thermal throttling. The result is a card that behaves as predictably at the end of a long day as it does the moment you first hit record.

Intelligent power-loss protection is built into every Capture+ card, and on the 4TB it is more important than ever. When you have hours of footage on a single card, the last thing you want is a power interruption corrupting your files. Glyph's built-in safeguards buffer in-flight writes and initiate a safe, controlled shutdown if the camera loses power unexpectedly. Combined with advanced thermal and power management that minimizes draw on your camera battery, the 4TB Capture+ is engineered to protect your work at every stage of the shoot.

Every Capture+ card is built to survive the conditions professionals actually shoot in, and the 4TB is no different. It is rated for operation between -12 and 72 degrees Celsius (10 to 162 degrees Fahrenheit) and tested to withstand extreme temperatures, moisture, dust, shock, x-ray, and magnetic fields. It is fully compliant with the CFexpress Type B 4.0 specification and backward compatible with CFexpress 1.0 and 2.0 devices - broad enough to fit into a wide range of camera bodies across multiple generations.

For media this critical, Glyph backs the 4TB Capture+ with an industry-leading 5-year warranty: full hardware replacement, 5-year Level-1 data recovery service, and 5-year advanced overnight replacement. Certified CE, FCC, WEEE, VCCI, RCM, UL, and RoHS, and supported by over 32 years of professional storage expertise, the 4TB Glyph Capture+ is the ultimate CFexpress card for professionals who shoot big and cannot afford to lose a frame.
