Video Speed Classes were introduced in February 2016 in response to the industry adoption of multi-file and ultra-high-definition 4K/8K, 3-D and 360-degree video recording, all of which require extended capture performance of up to 90 MB/s. microSD also can accommodate additional capabilities, such as near-field communications (NFC) and Secure Elements in SMART microSD memory cards. It developed the Ultra High Speed (UHS) standard to speed the processing of massive amounts of data between a device and a memory card. Over time, the SDA implemented microSD, microSDHC and microSDXC card standards for manufacturers to meet increasing storage needs. New design features and capacity expansions support a number of markets, including mobile phones, tablets, drones, and professional and consumer video cameras. Specified and standardized by the SD Association (SDA), microSD memory cards are continually improved and tested. In the past, many applications only required sequential writing to a card, but now they need to be able to handle both sequential and random writes to accommodate sound, photos, videos and applications. The fingertip-size microSD memory cards deliver value to consumers and manufacturers across numerous industries, making products more affordable for consumers while enhancing the capabilities of the product itself. Consumers can quickly use up a phone’s factory storage and need expandable options – which is one reason why, according to Strategy Analytics, SD memory card usage will continue to rise. Higher-resolution content means each picture or video size is much larger plus, these photos and videos now store geolocation and other metadata, further increasing the file sizes. The rise of photo- and video-centric apps like Snapchat and Instagram especially have fueled the need for larger amounts of storage as higher-quality smart phone cameras continue producing higher-resolution photos and videos. Despite the massive storage capacities available today, they won’t be enough to deal with the explosion of higher-resolution video and photos, not to mention the sheer numbers of photos taken every year: InfoTrends predicts 1.2 trillion photos will be taken in 2017. The Growth of Mobile Phone Storage NeedsĬurrent capacities for microSD memory cards range from 1 GB to 512 GB, depending on the manufacturer, and with technologies continuing to advance, it won’t be long before there is a 1 TB card on the market. The ability to store content locally and access it via smartphone will be necessary as long as the creation and consumption of data continues to grow at its rapid pace – and microSD memory cards can create a consistent, seamless and enjoyable user experience while also providing local data storage. As long as data caps, wireless network gaps and security concerns continue to exist, there will always be challenges retrieving content over open networks.
