I'm looking to replace some of my smaller cards with larger ones, preferably with at least a consistent, minimum 30MB/s write speed. So, realistically, I'm looking for 400x cards or so, or 266x at the minimum.
A few fast (400x+) 32/64GB cards are optimal (for video), but I'll definitely consider slower cards for photography. However, I'm not looking to spend too much since this isn't urgent and the CAD isn't doing too well at the moment. A bundle with a bundle price is likely ideal.
