Exascend 256GB Essential Pro CFexpress 4.0 Type B Memory Card

Exascend 256GB Essential Pro CFexpress 4.0 Type B Memory Card The Exascend 256GB Essential Pro CFexpress 4.0 Type B Memory Card is a high-capacity storage solution built on the PCI-Express 4.0 bus, delivering maximum read speeds of 3700 MB/s and maximum write speeds of 3150 MB/s. With a 256 GB storage capacity and a Type B form factor, this card is engineered for demanding data-intensive workflows that require rapid file transfer and reliable sustained recording performance.

PCI-Express 4.0 Bus Architecture

The card leverages the PCI-Express 4.0 bus interface, which provides the high-bandwidth pathway necessary to achieve its documented maximum read speed of 3700 MB/s and maximum write speed of 3150 MB/s. This bus technology enables the card to handle large data transfers efficiently, supporting workflows that involve moving substantial amounts of footage or image files between the card and a compatible host device.

Sustained and Minimum Write Performance

Beyond peak speeds, the Essential Pro maintains a sustained write speed of 3400 MB/s for reads and 900 MB/s for writes, ensuring consistent throughput during extended recording sessions. The card also guarantees a minimum write speed of 400 MB/s, which provides a defined performance floor for continuous data capture. This combination of sustained and minimum write speeds supports stable recording operations where consistent data flow is critical.

VPG-400 Video Performance Guarantee

The card carries a VPG-400 video performance guarantee, a specification that certifies a minimum sustained write speed of 400 MB/s for video recording applications. This documented performance level ensures the card can maintain the required data rate for high-bitrate video capture, providing a clear standard for recording reliability without requiring additional
