Toshiba has unveiled its UHS-II EXCERIA PRO N502 SD cards, a new line of memory cards for the European market designed specifically for capturing 4K and 8K ultra-HD video.

The UHS-II EXCERIA PRO SD cards, which will come in 32GB, 64GB, 128GB and 256GB capacities, have a minimum data transfer speed of 90MB/s, the requirements for the Video Speed Class 90 label they've been given (which vastly exceeds the U3 and Class 10 designations the cards also carry). The maximum read speed is 270MB/s, while the maximum write speed is 260MB/s.

In addition to being x-ray proof, shockproof and waterproof, the EXCERIA PRO N502 SD cards can withstand temperatures ranging from -25ºC to 85ºC (-13ºF to 185ºF) without condensation. Each card includes a five-year warranty when purchased through an authorized retailer.

The cards appear to be limited to the UK, Denmark, Finland, Ireland, Italy, Netherlands, Norway, Spain, Sweden, Switzerland and Turkey for the time being, with no listings currently available.
