Why Older SD Memory Cards Are Still Relevant

The SD memory card was born in the year 2000, when Bill Clinton was completing his second term as president of the United States. Sixteen years in human time may sound short, but in electronic technology time, it is an eternity. 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.

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. 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.

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.

But 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.
