To compete with NVMe SSD, Sony 128GB CFexpress memory card was released

According to the news of March 2, the SD association previously announced the next-generation microSD standard with a writing speed of about 1GB/s. It can be predicted that the SD card market will soon usher in a wave of upgrades. And the CompactFlash Association (CFA) has also previously announced CFExpress 2.0 standards to allow CFE cards to compete with NVMe PCIe.
 

SONY officially announced on February 27 that it will launch a 128 GB Type-B CFexpress memory card, and Officials say it can read at speeds of up to 1700MB/s and write at speeds of up to 1400MB/s. Although it still does not reach the current level of advanced NVMe SSD (Speeds of about 3000MB/s), it can already compete with NVMe SSD.

Officials say 256GB and 512GB versions are also on the way. As a tie-in, Sony has also launched a MRW-G1 card reader, which will officially go on sale with the memory card this summer.

These CFE cards are mainly aimed at the camera market. According to Addiction Technologies, the first camera to benefit will be Nikon Z6, which will receive the support of CFExpress 2.0 through the update in the near future.
