AdrianWarren.com: Reviews: Canon EOS 400D
The EOS 400D's performance was excellent for an entry level model, with no real issues. The excellent writing performance of the camera means that it will benefit from using the fastest cards particularly if you're shooting bursts.

Sandisk Ultra II 4GB, RAW images
The continuous shooting test was carried out at fixed settings, and as a result the images are slightly smaller than average. This doesn't impact the performance significantly, but remember that the filesizes below will be at the low end of the scale.
| JPEG large/fine | 1363kB |
| RAW (.CR2) | 7848kB |
| RAW + JPEG large/fine | 9080kB + 1363kB = 10443kB |
Note that the filesize of the RAW file also increases when you select RAW + Large/Fine JPEG. In this situation the camera appears to be embedding the fullsize JPEG within the RAW file in addition to creating another separate JPEG file at the same time; this behaviour is present even in the latest firmware available at time of writing (1.1.1).
