Exascend 256GB CFX Series CFast 2.0 Memory Card

Exascend 256GB CFX Series CFast 2.0 Memory Card The Exascend 256GB CFX Series CFast 2.0 Memory Card is a SATA III-based storage solution designed for high-throughput capture workloads. With a 256GB capacity and sequential read speeds of 550 MB/s, this card is built to handle demanding data-intensive recording sessions.

High-Speed Sequential Performance

The card delivers sequential read speeds of 550 MB/s and sequential write speeds of 530 MB/s over its SATA III bus interface. This level of sustained throughput supports continuous data transfer for applications that require rapid ingestion and offloading of large files.

Sustained Write Stability for 4 kB Files

When working with smaller 4 kB file sizes, the CFX Series card maintains a sustained write speed of 500 MB/s and a sustained read speed of 520 MB/s. This consistency across file sizes ensures that performance remains stable even when the storage system is handling fragmented or smaller data blocks.

Random Access Performance

For random read operations involving 4 kB files, the card achieves up to 85,000 IOPS, while random write operations reach up to 70,000 IOPS. These random access capabilities support efficient handling of non-sequential data patterns, which is useful for file management and retrieval tasks.

Operating and Storage Temperature Range

The memory card is rated to operate in temperatures from 23 to 158°F (-5 to 70°C) and can be stored in conditions ranging from -40 to 185°F (-40 to 85°C). This documented temperature tolerance defines the environmental envelope within which the card can function and be kept when not in use.
