Being UHS Speed Class 3 (U3) enabled, these new Toshiba microSD memory cards will enable high-quality 4K video capture at constant minimum write speeds of 30MB/s. This translates to the ability to record 4K2K video, live broadcast and content on high-performance cameras without missing a beat or suffering from a drop in quality.
The 64GB cards do come with a maximum read speed of 260MB/s and a maximum write speed of 240MB/s. As for the smaller capacity 32GB cards, these have a maximum read speed of 145MB/s and maximum write speed of 130MB/s, which would represent an 8x write speed improvement and 2.7x read speed improvement if you were to take Toshiba’s existing 32GB microSD UHS-I cards and place them in a side-by-side performance comparison. There is no word on pricing details for either capacity just yet though. [Press Release]
