There are still use cases, however, that don’t need these bells and whistles – such as applications in industrial segments that run on variants of Linux or Windows Embedded OS, or Real-Time OS (RTOS) such as WindRiver VxWorks and QNX. Consumers, meanwhile, demand the lowest cost per gigabyte. ![]() Other applications need cards with large amounts of data storage, such as those storing 360-degree video. Some applications, like 4K/8K video, require SD memory cards with blazing-fast transfer speed for highest bandwidth and throughput. The incredible speed at which SD standards evolve is nothing short of amazing – in fact, the SD Association just announced the latest version: 5.0, with new Video Speed Classes to satisfy the latest 4K/8K Ultra HD video, 360-degree video and multi-file recording demands.īut even though the consumer electronics and digital imaging markets drive the leading edge of SD technology innovations, there remains a strong and healthy demand for older generations of SD memory cards, namely SD or SDHC memory cards varying in capacity from 128 MB up to 8 GB. We started with the initial SD version 1.0, using FAT16 and with storage capacity up to 2 GB then on to SD v2.0 (SDHC), using FAT32 and with storage capacity up to 32 GB and now to today’s v3.0 (SDXC) using ex-FAT and with a massive storage capacity of up to 2 TB. Over the years, SD technology innovations have accelerated to keep up with market demands for ever-increasing storage space and faster speeds, all at a reasonable cost. ![]() ![]() Today, more than a billion SD memory cards are being manufactured and sold around the world every year they have truly become the de facto standard for removable storage. Sixteen years in human time may sound short, but in electronic technology time, it is an eternity. The SD memory card was born in the year 2000, when Bill Clinton was completing his second term as president of the United States.
