![]() The Video Speed Classes defined by the SD Association are V6, 10, 30, 60 and 90, assuring 6, 10, 30, 60 and 90MB/s respectively. Hosts that support Video Speed Classes may utilize cards with new memory technologies more efficiently, helping videographers and filmmakers as they record higher definition video in 4K and 8K and require faster read/write speeds. Video Speed Class was introduced along with the introduction of newer memory technologies.UHS Speed Class 1 and UHS Speed Class 3, indicates assurance of a minimum write speeds of respectively 10MB/s and 30MB/s. As the interface speed capability increased with the introduction of Ultra High Speed (UHS) SD interface, UHS Speed Class was introduced.There are three types of speed assurance ratings that have historically evolved as the card interface advanced as well as the memory technology evolution: Speed Class, UHS Speed Class and Video Speed Class. The memory card speed is the minimum speed at which the memory card’s continuous write is assured, which can significantly impact the workflow of a photography project. Thanks to the continuous progress in the space of SD memory card standards, high-speed memory cards are available to solve customer needs. With the demand for speed now seen as a requirement by photography applications, especially when shooting HD/4K video, SD memory cards become essential in fulfilling those needs. “While it is true that HD video produces large files, digital RAW files produce more data in a shorter period of time when photographers shoot a quick burst of multiple RAW files.” highlighted that the reason speed is important in photography is because of the file size of the images. “You might not think too much about how fast your SD cards are, but picking the right memory card can upgrade your gaming experience, help you take better photos, and even make it possible to record super high-resolution video.” ![]() Since memory cards and digital photography go hand in hand, there are still questions raised by photographers, videographers and professionals on what they should look for when choosing the right memory card.Ī recent piece in WIRED Magazine discussed the value of super-fast SD memory cards available to users today. And let’s not forget the proliferation of 360-degree cameras, drone imaging and UHD action cameras to name a few. The number of travel and nature photographers keeps growing and the number of moments people capture with their smart phones grows every day. All these features allow the photography and video industry to advance and meet the rigorous demand of higher resolution images and larger capacity needs-demonstrating that it’s not just a question of squeezing more images onto a memory card.ĭigital photography and videography have expanded beyond anything the early pioneers of photography could have ever imagined. In this article, we will look at some of the features of these innovative memory cards, including SD Express that delivers the fastest data transfer speeds and the newly released specification SD 9. The truth is the world of video and digital photography that we know and love today would never have been able to get to where it is without one key technology: SD memory cards. The digital photography market was valued at $44.7 Billion in 2021 and according to recent research, it is projected to reach $58.41 Billion by 2030.
