Glyph Capture+ CFexpress Type B 4.0 Memory Card – 512GB

The Glyph Capture+ CFexpress Type B 4.0 512GB combines a PCIe 4.0 x2 interface with Glyph's SteadyIO technology for professional camera workflows where consistent sustained recording performance is important. Compared with the 256GB version, this 512GB model provides materially higher write and sustained-write performance as well as twice the recording capacity.

Glyph's own compatibility guidance shows the 512GB version as recommended for a broader range of demanding camera workflows than the 256GB card, although exact codec, frame-rate and recording-mode support should still be checked for the camera in use.

512GB Performance Profile

This exact 512GB model is specified for up to 3700MB/s read, 1300MB/s write and 1100MB/s sustained write. These figures are capacity-specific and should not be confused with the lower 256GB write figures or the substantially higher performance of the 1TB, 2TB and 4TB versions.

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 512GB version offers a substantial step up from the 256GB model and is marked as recommended by Glyph for many professional cameras and recording workflows. 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.
