Glyph Capture+ CFexpress Type B 4.0 Memory Card – 4TB

The Glyph Capture+ CFexpress Type B 4.0 4TB is the highest-capacity model in Glyph's Capture+ CFexpress Type B 4.0 range. It combines 4TB of recording capacity with the family's top specified write performance, making it particularly suitable for high-data-rate cinema, extended recording sessions and workflows where card changes need to be minimised.

The exact 4TB model is specified for up to 3700MB/s read, 3500MB/s write and 3000MB/s sustained write, with Glyph's SteadyIO technology designed to maintain stable throughput across sustained workloads.

4TB Performance Profile

The 4TB model is specified for up to 3700MB/s maximum read, 3500MB/s maximum write and 3000MB/s sustained write. These are the highest write figures in the current Capture+ family and are shared with the 2TB version.

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 the performance limitations of the host.

SteadyIO Sustained Performance

Glyph's SteadyIO technology is designed to maintain consistent read and write behaviour across large sustained workloads, helping reduce throttling and performance variation during long recording sessions or high-volume ingest.

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 and power draw during sustained operation.

Data Protection And Durability

The Capture+ card includes overheat protection, ECC, EMS protection, SMART, TRIM and power-management functions together with EDC/ECC data-resilience features. Glyph also specifies resistance to extreme temperature, moisture, dust, shock, x-ray and magnetic exposure.

High-Capacity Professional Recording

With 4TB of capacity and the highest sustained-write specification in the Capture+ range, this version is intended for extended high-resolution recording and other workflows where both sustained bandwidth and recording duration matter. Physical CFexpress Type B compatibility does not guarantee every codec or frame rate, so exact camera and recording-mode support should still be checked before deployment.
