Exascend 128GB CFX Series CFast 2.0 Memory Card

Exascend 128GB CFX Series CFast 2.0 Memory Card The Exascend 128GB CFX Series CFast 2.0 Memory Card is a high-capacity storage solution built on the CFast 2.0 standard with a SATA III bus interface. With 128GB of storage capacity, this card is engineered to deliver substantial sequential read and write speeds for demanding data-intensive workflows.

Sequential Read and Write Performance

The card is specified for sequential read speeds of 550 MB/s and sequential write speeds of 530 MB/s. These figures indicate the card's capability to handle large data transfers efficiently, which is a critical factor when moving substantial amounts of footage or image files between the card and a host device.

Sustained Speed for Small File Transfers

Beyond sequential performance, the CFX Series card maintains high throughput when working with smaller data. It delivers sustained read speeds of 520 MB/s and sustained write speeds of 500 MB/s when handling 4 kB files. This sustained performance on small file sizes is a distinct characteristic of the card's design, addressing workflows that involve numerous smaller data packets rather than only large contiguous files.

Random Access Performance

The card's random read performance is rated at 85,000 IOPS, while its random write performance is rated at 70,000 IOPS, both measured with 4 kB files. These input/output operations per second metrics provide insight into the card's ability to handle fragmented data access patterns, which can be a relevant factor for certain recording or file management operations.

Operating and Storage Temperature Range

The CFX Series card is specified to operate within a temperature range of 23 to 158°F (-5 to 70°
