Memory manufacturer Lexar has announced it will double the capacity of its 3500x CFast memory card this quarter taking the storage capability to a massive 512GB. The Lexar Professional 3500x CFast 2.0 card will offer write speeds of up to 445MB/s, but will cost an equally impressive $1699.99/£1732.99. The company says that the card is designed to be used by movie makers, especially those using memory-intensive techniques such as super-high frame rates for slow motion footage and those shooting in 4K resolution and in Raw formats.

The card will obviously record stills as well as video, but the attraction is the length of uninterrupted footage that can be recorded. Stills photographers are likely to be better off buying smaller versions of the card which cost less per GB. At $675 the 256GB version is less than half the price for half the capacity, though buying 16 32GB cards works out more expensive and the write speed is slower.

The new card has a maximum read speed of 525MB/s, so allows users to copy data from it to another drive very quickly. Lexar supplies a ‘lifetime’ copy of its Image Rescue recovery software that it claims can bring back data even from corrupted cards, as well as a limited lifetime warranty and technical support.
