SD Express will enhance transfer speeds up to 985 megabytes per second through the PCIe interface and, significantly, the format will be able to increase storage capacity up to a whopping 128 terabytes.
Previously, the maximum storage capacity available in memory cards was 2 TB with the SDXC, released back in 2010, although this size of card is still rare to find.
The new 128 TB memory cards will be called SD Ultra Capacity (SDUC), but there is no word yet when they could become available.
Consumers still pay upwards of US$100 (RM404) for 256 GB SD cards, so we can expect 128 TB cards to cost a pretty penny whenever they do arrive.
Regardless, this announcement is a big deal and means that soon, memory cards will be able to be used for devices and applications that move large amounts of data at high speeds, for example for mobile phones, gaming systems or cameras.
