Exascend 256GB Essential Pro CFexpress 4.0 Type A Memory Card

Exascend 256GB Essential Pro CFexpress 4.0 Type A Memory Card The Exascend 256GB Essential Pro CFexpress 4.0 Type A Memory Card is a high-capacity storage solution built on the PCI-Express 4.0 bus, delivering a maximum read speed of 1800 MB/s and a maximum write speed of 1650 MB/s. With 256GB of storage capacity, this card is engineered for demanding capture workloads that require rapid data transfer and consistent recording performance.

PCI-Express 4.0 Bus Architecture

The card utilizes the PCI-Express 4.0 bus interface, which provides the data pathway for its high transfer rates. This bus technology enables the card to achieve a maximum read speed of 1800 MB/s and a maximum write speed of 1650 MB/s, allowing for fast offloading of large files and efficient handling of data-intensive recording sessions.

Sustained Write Performance and VPG-400 Guarantee

Beyond peak speeds, the card maintains a sustained write speed of 1800 MB/s for reads and 850 MB/s for writes, with a minimum write speed of 400 MB/s. This minimum write threshold is reinforced by the VPG-400 video performance guarantee, which certifies that the card can sustain a write speed of at least 400 MB/s. This specification is critical for uninterrupted recording of high-bitrate video, ensuring the card can keep pace with continuous data capture without dropping frames.

Operating and Storage Temperature Range

The memory card is designed to function within an operating temperature range of 10 to 161°F (-12 to 72°C), covering a broad spectrum of ambient conditions. For storage, the card can withstand temperatures from -40 to 185°F (-40
