Sony has announced a new line of G Series CFast 2.0 memory cards, with a maximum writing speed of 510MB/s and reading speeds of 530MB/s, available from early 2018.

The cards come in 32GB, 64GB, and 128GB capacities. Each have a minimum sustained write speed of 130MB/s, Sony says, making the cards ‘far outperform the capabilities of existing CFast cards.

They’re designed for professional photographers and videographers creating large image or video files with a high frame rates.

The cards support VPG130, for high-bitrate 4K video recording.

Sony produces a range of memory cards, and designed the first batch of XQD cards, which fiercely compete with CFast cards.

Most Sony mirrorless interchangeables don’t use CFast cards, and the company tips XQD as the future. However, Canon stills and video cameras remain committed to CFast 2.0.

Sony Electronics US announced the cards, with a ‘suggested retail price of US$119.99 for 32GB, US$199.99 for 64GB and US$349.99 for 128GB.
