Exascend 1TB CFX Series CFast 2.0 Memory Card

Exascend 1TB CFX Series CFast 2.0 Memory Card The Exascend 1TB CFX Series CFast 2.0 Memory Card is a high-capacity storage solution built around the CFast 2.0 form factor and SATA III bus interface. With a 1 TB storage capacity, this card is designed to deliver substantial space for demanding data capture workflows, supported by sequential read speeds of 550 MB/s and sequential write speeds of 530 MB/s.

Sustained Write Performance

The card is specified for sustained write speeds of 500 MB/s when handling 4 kB files, which is a key metric for continuous recording scenarios. This sustained write capability is paired with a sustained read speed of 520 MB/s for 4 kB files, ensuring that the card maintains consistent throughput during extended write operations rather than only achieving peak speeds in short bursts.

Random Access Performance

For workloads involving small file transfers, the card provides random read performance of 85,000 IOPS and random write performance of 70,000 IOPS, both measured with 4 kB files. This random access capability addresses scenarios where data is read or written in scattered locations across the storage medium, complementing the card's sequential performance characteristics.

Operating and Storage Temperature Range

The CFast 2.0 card is rated to operate within a temperature range of 23 to 158°F (-5 to 70°C), covering typical ambient conditions encountered during active use. When not in operation, the card can be stored in environments ranging from -40 to 185°F (-40 to 85°C), providing a wider tolerance for storage between recording sessions.
