Answering Your Questions about Industrial CFexpress

Delkin CFexpress


The challenge with today’s industrial devices is designing them to meet two competing demands: users need devices that are small in size, but powerful in terms of storage and speed. Fortunately, advances in the embedded memory marketplace have made it possible to achieve both of those goals, with smaller-than-ever memory cards that offer previously unheard of storage capacities and speeds. One example of such a memory solution is CFexpress.


Industrial CFexpress represents the evolution of the ever-popular CompactFlash storage design. It provides high-speed, removable storage that is capable of meeting the needs of today’s host devices across industrial markets. For industrial applications with high-capacity storage needs in rugged operating environments, CFexpress is a next-generation solution that provides both the speed and the security necessary for these types of devices.


How does industrial CFexpress differ from traditional CompactFlash?

CompactFlash is one of the oldest embedded storage standards on the market today. That standard has survived so long thanks to its ability to adapt to evolving technologies. CFexpress is the latest development in that evolution. The design allows for extremely high-speed and high-resolution recording with low latency, but within a small form factor. The size of the CFexpress card is the same as the familiar XQD format.


While the speed, size, and interface set CFexpress apart from traditional CompactFlash designs, one thing that remains the same is the work of the CFA, or Compact Flash Association. The CFA sets the specifications for CFexpress that all manufacturers adhere to, so users can rely on consistent compatibility.


What are the advantages of using CFexpress in your device?

Designers of industrial devices have important considerations to keep in mind when choosing embedded memory cards. CFexpress is an ideal choice because it offers the speed, low latency, and high-resolution performance of the PCIe® interface, while allowing the NVM Express® protocol to be used without having to incorporate a larger memory card. It is possible to achieve read speeds of up to 1,600 MB/s and write speeds of up to 1,000 MB/s with this design. The low power consumption of CFexpress is also an important feature that makes it appealing to designers.


Delkin produces 3D industrial CFexpress cards in a number of different storage capacities, including 128GB, 256GB, and 512GB. The card is removable and encased in metal, giving users the maximum in flexibility and ruggedness.


What makes the CFexpress card ideal for industrial markets?

CFexpress has been adopted across multiple industries with vastly different storage needs, thanks to its speed, reliability, and flexibility. Industrial CFexpress meets the typical requirements for use in industrial devices. It offers an extended temperature range of -40 degrees C to 85 degrees. It can also withstand high levels of shock and vibration without any risk of data loss; this is a particularly important feature given the rugged operating conditions of many industrial applications.


Industrial CFexpress also comes with a locked BOM, or bill of materials. This critical feature ensures that no changes will be made to any of the core components of a CFexpress card that could affect device compatibility without advanced notification and a new product number. A locked BOM prevents widespread, unexpected failures from occurring and leading to costly device downtime. With advanced notification of any potentially consequential changes to the CFexpress card design, users can conduct new qualification testing and create a plan for transitioning to a new card.


Additionally, industrial CFexpress from Delkin comes with dedicated lifecycle management. Simply put, every memory card has a finite lifespan. Understanding how long an embedded memory card is likely to last is an important part of avoiding device downtime. Delkin can help users understand how long a CFexpress card will last in their device and assist them in planning to transition to replacement cards in the least disruptive way possible. Delkin can also provide customized testing of CFexpress cards in customers’ devices to determine if they are the best fit and if there are changes that could be made to extend the lifespan and improve the efficiency of the memory cards.


What industries should consider CFexpress cards?

Virtually any industrial device could benefit from using CFexpress cards. Anyone in need of a high-speed memory card to use in demanding conditions has a use for CFexpress cards. As such, you can and will find it being used across many different industries with varying needs.


Industrial CFexpress cards are particularly popular with industrial users who have a need for video recording and photography. High write speeds, large capacities, and low latency rates make it possible to record and store high-resolution video with less frequent card replacements and without compromising video quality. Industrial video surveillance systems, military video recordings, medical imaging and video, and film and television recording are just a few examples of scenarios in which industrial CFexpress cards are a good fit. As technology continues to evolve, experts anticipate storage capacities to increase even further for CFexpress cards, which will only increase the demand for this kind of embedded storage.


Users who get their industrial CFexpress cards from Delkin also benefit from a range of customization options. Delkin can make a number of configuration customizations to CFexpress cards to ensure users get the maximum efficiency possible from their cards. The customer applications team achieves these outcomes by taking the time to understand exactly how the memory card will be used and the specific design of the device. Through individualized testing, our team can help you determine the best configurations for your application. Delkin also offers customization options like serialized numbering, conformal coating, custom packaging, and much more.
