Glyph Capture+ CFexpress Type B 4.0 Memory Card – 1TB

The Glyph Capture+ CFexpress Type B 4.0 1TB combines a PCIe 4.0 x2 interface with Glyph's SteadyIO technology for professional camera workflows where consistent sustained recording performance is important. The 1TB model provides a substantial step up in sustained write performance over the 512GB card while retaining a practical capacity for demanding cinema, video and high-resolution stills workflows.

Glyph's compatibility chart groups the 1TB and 2TB models together for recording performance, reflecting their shared 2500MB/s maximum write and 2100MB/s sustained write figures. Exact codec, frame-rate and recording-mode support should still be checked for the camera in use.

1TB Performance Profile

This exact 1TB model is specified for up to 3700MB/s read, 2500MB/s write and 2100MB/s sustained write. These figures are shared with the 2TB version but differ from both the slower 256GB/512GB cards and the faster 4TB model.

CFexpress 4.0 Type B / PCIe 4.0 x2

The card uses the CFexpress Type B 4.0 specification with a PCIe 4.0 x2 interface. Glyph also specifies backward compatibility with CFexpress 1.0 and 2.0 devices, allowing use with compatible earlier-generation Type B equipment subject to host limitations.

SteadyIO Sustained Performance

Glyph's SteadyIO technology is designed to maintain stable read and write behaviour across large sustained workloads, helping reduce throttling and performance variation during extended recording or ingest operations.

Power-Loss And Thermal Protection

Intelligent power-loss handling is designed to protect in-flight writes if camera power is unexpectedly lost. Advanced thermal and power management helps control heat generation and power draw during sustained operation.

Data Protection And Durability

Built-in overheat protection, ECC, EMS protection, SMART, TRIM and power-management functions are specified alongside EDC/ECC data-resilience features. Glyph also describes the Capture+ cards as resistant to extreme temperature, moisture, dust, shock, x-ray and magnetic exposure.

Camera Compatibility Matters

The 1TB version is marked as recommended by Glyph across a broad range of professional cameras and is particularly better suited than the lower-capacity cards to high-data-rate recording. Physical CFexpress Type B compatibility alone does not guarantee every codec or frame rate, so the exact camera and recording mode should still be checked against Glyph's compatibility chart and the camera manufacturer's approved-media guidance.

Warranty And Recovery Support

Glyph provides a five-year hardware warranty on the Capture+ card together with five years of Level-1 data recovery and five years of advance replacement support.
