New SD cards specification

Soon we will have SD cards with 128TB of storage

The SD Association has revealed a brand-new card specification that should increase maximum storage on SD cards to 128 terabytes and offer much faster data transfer speeds of 985 megabytes per second.

Today the maximum storage space on an SD card is 2TB, and that limitation was promised as far back as 2009, but still hasn't been reached. In 2016, SanDisk revealed a prototype 1 terabyte SD card that would make it the biggest in the world, but it's still not offered to purchase. At the time, SanDisk stated that the improvement was needed to match ever-increasing data-heavy formats like 4K video and VR. However, producing SD cards with enormous amounts of storage is cost-prohibitive. SanDisk's 512GB SD card used to cost $800, and though it's dropped in price, is still priced around $300.

The new faster speeds, called SD Express, will come to all types of cards, but the high storage is a brand-new thing called an SD Ultra Capacity (SDUC) card. Given how slow the development has been toward 2TB cards, there's no informing how long it'll take before producers hit the greater figures that SDUC enables, but maybe the increased storage capacity and shift to significantly higher-resolution video will offer companies more reason to invest.
