Glyph Technologies 4TB Capture+ CFexpress 4.0 Type B Memory Card
The Glyph Technologies 4TB Capture+ CFexpress 4.0 Type B Memory Card is engineered for creators who demand reliable, high-speed performance in real-world production environments. With a massive 4TB capacity, it delivers read speeds up to 3700 MB/s, write speeds up to 3500 MB/s, and sustained write speeds of 3000 MB/s—making it well suited for 12K+ raw video, high-resolution image sequences, and rapid continuous shooting. SteadyIO technology ensures consistent transfer speeds across extended workloads without throttling or thermal slowdowns.
Built on the CFexpress 4.0 standard using a PCIe 4.0 x2 interface, the card is also backward compatible with CFexpress 2.0 and 1.0 devices for added flexibility. An advanced thermal design supports stable performance during long recording sessions, while integrated safeguards help protect data by saving buffer files and safely shutting down in the event of power loss or sudden removal.
Designed for durability in demanding conditions, the Capture+ card offers resistance to temperatures from 10 to 162°F, as well as protection against moisture, dust, shock, X-rays, and magnets—making it a dependable solution for professional photo and video workflows.
Performance with Purpose
Real-world read speeds of up to 3700 MB/s and write speeds of up to 3500 MB/s, with sustained write speeds of up to 3000 MB/s, help tackle 12K+ raw video capture and fast burst raw image sequences.
SteadyIO Technology
SteadyIO technology delivers consistent, uninterrupted read and write speeds across the full capacity, so you won't miss a frame.
Intelligent Power-Loss Handling
Designed to protect in-flight writes in case of camera power loss. Built-in safeguards save buffer files and safely shut down the card.
Advanced Thermal and Power Management
Capture+ cards operate with minimal power draw to preserve camera battery and smartly manage thermals to prevent overheating.
Designed to Endure
Glyph Capture+ cards resist extreme temperatures, moisture, dust, shock, X-rays, and magnets.
Fully Compliant
This card adheres to the CFexpress 4.0 Type B specification and is backward compatible with CFexpress 2.0 and 1.0 devices.
Limited 5-Year Warranty with Level-1 Data Recovery and Advanced Overnight Replacement
The limited 5-year warranty includes overnight advanced replacement and level-1 data recovery to give you peace of mind where it is needed most - your media.
