[QUOTE="aroy, post: 349618, member: 16090"] Today I tried the class 4 4GB card that came with the camera. A small green light; which used to come on when ever I took/put the battery; was lighting up. Must be indication writing. Never noticed the light with my 45Mbps 32GB card. So definitely the faster card helps. Just to figure out what speed is required for continuous 6fps . 14bit RAW 24MP file will be approximately 42MB before compression. If it is compressed to 24MB, you will need about 150Mbps write speed. . 12bit RAW 24MP file will be approximately 36MB before compression. If it is compressed to 20MB, you will need about 120Mbps write speed. . 14bit RAW 16MP file will be approximately 28MB before compression. If it is compressed to 16MB, you will need about 96Mbps write speed, well within the available card speeds. Have to find out if D4S can shoot continuously at 6fps. That means we have to wait for Nikon to speed up its I/O to cater to 150 Mbps+ cards. Once it does that, we can expect continuous shooting at 6fps at least with 24MP sensor. [/QUOTE]
