Quote from: moomilk on May 20, 2013, 07:12:34 PMToshiba is the second largest producer of flash cards after SanDisk so it doesn't sound unreasonable. They have also developed the worlds fastest SD cards with write speeds over 250 MB/s (too bad Canon's SD slot is limited to 20MB/s).
Toshiba 1066x claims to have 150Mb\s write speed, Transcend 1000x also might be worth checking as it should be capable of ~120Mb/s
This is one case where the speed of the card is greatly superior to any device capable of supporting it. Lets just hope Canon gets the memo come the release of 5D Mk IV.
