Major changes to SD cards are coming.
Recently, SD association has announced a new standard - SD Express which can revolutionize removable storage.
However, you may find many standards and variations in performance turn quite confusing when looking into it.
Over the last few years, things have become much worse with more icons and labels.
This means SD Express is much faster than the SD card available currently in read and write speeds.
Besides, it also means higher capacity, which can reach up to 128TB.
Currently, the maximum capacity is 2TB.
PCIe interface can deliver the data transfer speed up to 985MB/S.
Is SD Express Card Backward Compatible?
The answer is Yes.
Like the older SD cards, SD Express cards have the same connecting pins.
However, there is still a limiting factor: capacity.
Thus, an SDUC card can only be used in an SDUC reader or gadget.
Likewise, an SDXC card cannot work in a reader that only supports SDHC.
Hence, you should limit the read and write speeds in your laptop, camera or drone to 50MB/s.
Where Can SD Express Used?
The new cards will be initially used on SDXC, SDUC, and SDHC memory cards.
These changes maintain the SDAs commitment to backward compatibility and are a part of the new SD 7.0 specification.
Final Words
SD Express will revolutionize removable storage.
If you are interested in this new card, c’mon pay attention to this industry.
