Exascend Essential Pro CFexpress A 4.0 1TB card

The Essential Pro CFexpress 4.0 Type A is a top-of-the-range memory card created with professional filmmakers in mind. The Exascend-branded card is distinguished by its innovative CFexpress 4.0 technology, enabling unprecedented high levels of continuous reads - 1800 MB/s - and writes - 1650 MB/s. This makes it possible to provide 8K and higher resolution at any frame rate - without loss. The implementation of RAID ECC technology ensures that corrupted data can be recovered, increasing the security of stored information. This is another Exascend-branded card that has achieved VPG400 certification, highlighting its high performance and reliability.

The Essential Pro CFexpress 4.0 Type A also features a robust design that is resistant to dust, shock, harsh weather conditions and X-rays.

Exascend's integrated technologies, such as Adaptive Thermal Control™ and SuperCruise™, eliminate overheating and data loss issues for fast, efficient and comfortable use.

Exascend was founded in 2016, starting its business by providing robust SSD solutions for industrial and enterprise applications. The experience gained has enabled the company to expand its offering to reliable memory cards in the photo/video industry. Working with leading camera manufacturers, Exascend delivers state-of-the-art and robustly protected data storage systems.

Technologies used:

SuperCruise™ - Continuous recording of high-volume data, as in video recording, can result in a sudden drop in performance or interruption of recording. Exascend's brand technology eliminates this problem, guaranteeing unparalleled stability even during the most demanding applications. Unlike many competing brand systems, whose performance is preserved only during the initial stage of writing, the unique SuperCruise™ algorithm is responsible for ensuring that media performance is maintained until the end of the job.

RAID ECC (Error-Correcting Code) - a combination of two advanced data protection technologies. It detects and corrects errors that may occur during data transmission on two levels, both through storage in multiple flash memory blocks by RAID5 and an additional ECC algorithm. This makes it possible to recover even severely corrupted data. In addition, the technology improves system performance and extends the life of SSDs.

AdaptiveThermal Control™ - a.k.a. adaptive thermal control, which prevents the card from overheating. This innovative technology from Exascend works on the basis of a patented adaptive algorithm that precisely adjusts to environmental conditions. It constantly monitors and adjusts the overall performance of the drive during operation - when the temperature rises, the algorithm slightly reduces performance, only to increase it again when the temperature drops. Maintaining this delicate balance translates into the highest consistent performance, without any user or device intervention.

Afterburner™ - an innovative solution from Exascend that enables faster data writing and reading by using SLC cache. SSDs are characterised by slower write speeds, which is a direct result of the characteristics of NAND flash memory, where writing data requires deleting existing information in the target memory unit. Afterburner™ allocates segments of NAND memory units to operate in SLC mode and only then methodically transfers them to other storage sectors. The SLC cache stores individual bits of data, making it considered the most efficient and reliable - its mode of operation significantly speeds up write and erase processes, providing an optimal balance of performance and longevity. Furthermore, Afterburner™ technology automatically transfers data from the SLC cache to the 3D TLC NAND flash memory without affecting performance. In the context of regular use, the use of Afteburner™ facilitates the efficient management of daily write operations by SSDs.

Data Retention Plus™ - SSDs store data in NAND-type flash memory cells, which are characterised by a limited number of write/erase cycles. Over time, damage to these cells occurs, which becomes evident during overheating (higher voltages) or during extended write/erase cycles - but this process can be slowed down by controlling the cells to wear evenly. An algorithm developed by the Exascend brand allows data stored on flash memory devices to be dynamically refreshed, taking into account the current state of the memory. Disk consumption becomes more evenly distributed and data is properly protected. Even at maximum loads, this reduces the risk of loss of data integrity due to natural degradation of flash memory.

Smartstream™ - Exascend's unique technology that allows seamless support for continuous shooting and longer recording on the same card, balancing performance and optimal battery consumption. Smartstream™ analyses the current write pattern of the NAND flash memory, allowing the optimal SSD processor clock frequency to be selected. This increases performance and energy efficiency, resulting in more stable writes and better battery life.

Conformal Coating - a conformal coating technology that increases the card's resistance to external threats such as dust and moisture. The coating, which meets stringent military standards, is applied to both the circuit board and integrated components. The coating process itself provides a uniform layer of protection over the entire drive with the exception of the connectors.
