ExAscend EXPC4NB512GB Nitro Pro memory card, 512GB

Meet the Nitro Pro CFexpress 4.0 Type B 512 GB, the premium memory card from Exascend. Compared to the 2.0 standard, it offers twice the read and write speed - a true revolution in the market for flash memory solutions. It is designed for photography and film professionals who need a reliable and fast storage medium and the latest technology.Nitro Pro CFexpress 4.0 Type B 512GB is a premium memory card, created for the most demanding users who need a reliable and lightning fast storage medium. Perfect for professional video makers, film crews or photographers - especially when working in harsh environments.

The Exascend branded card stands out with lightning fast continuous read - 3500 MB/s - and write - 3300 MB/s. In addition, it can reach a maximum read speed of up to 3750 MB/s. With such fast data writing and reading speeds, it proves its worth for bandwidth-intensive tasks - such as RAW video recording at up to 12K quality or long continuous action photography. Thanks to the implementation of RAID ECC, it is equipped with the ability to recover corrupted data.

This is another Exascend-branded card that has received the VPG400 certification directly from the Compact Flash® organisation (see the list of certified devices on the CF website).

Nitro Pro CFexpress 4.0 Type B also features a robust design, resistant to shock and harsh weather conditions. The IP67 certification it has received confirms its resistance against water and dust, and it is also X-ray resistant. It performs even in the toughest conditions also thanks to its record-breaking operating temperature range: -30 ~ 85 degrees Celsius. The card's construction is made entirely of aluminium, which dissipates heat perfectly, providing thermal protection. Combined with Adaptive Thermal Control™ technology, the card's operating temperature is up to 20 degrees cooler than standard models.

Integrated technologies developed by Exascend eliminate problems such as overheating, frame or data loss, making working with the Nitro Pro CFexpress 4.0 Type B is fast, efficient and as comfortable as possible.

Nitro Pro CFexpress 4.0 Type B is the perfect choice for professionals who need fast, reliable and durable storage media for their tasks.

The Exascend brand was founded in 2016 and started its production by providing robust SSD solutions for industrial and corporate applications. The experience gained made it possible to expand the technical capabilities of the production line, so in 2020 Exascend expanded its business to include cards that are reliable in the photo/video industry. Through in-house production and partnerships with leading camera manufacturers, the brand provides modern 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 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, thanks to the use of an SLC cache. SSDs are characterised by slower write speeds, 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 apparent 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™: a unique Exascend-branded 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, enabling the selection of the optimum SSD processor clock frequency. 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 the integrated components. The coating process itself provides a uniform layer of protection over the entire drive with the exception of the connectors.
