Canon EOS 5D Mark II write speed (firmware version 2.1.2)
This page was last updated on May 23, 2012


The data in the table below was derived by timing how long it took the Canon EOS 5D Mark II to write 20 Large Fine JPEG and then 10 RAW CR2 photos to the memory card. Timing commenced when the camera's card status light illuminated, and stopped when the light went out. Each test cycle was performed three times (if the card's capacity allowed for that) to ensure accurate results. The data has been converted to megabytes-per-second (MB/s). Higher numbers are better.

The figure in the Burst column represents how many CR2 + JPEG pictures the camera was able to take in 30 seconds. Higher numbers are better, and a relatively small difference in the number of frames captured translates to a noticeable difference in how much faster one card feels than another, when shooting frequent extended bursts.

Prior to both JPEG and RAW CR2 testing, all CompactFlash cards were first secure erased on a computer, then formatted in the camera. This camera has also been tested with a handful of SD/SDHC cards inside an adapter. These cards were cleared for testing using the low level format option of an EOS Rebel T3i/600D. The same scene was photographed, under the same illumination, for all tests. The identical camera settings and lens were also used throughout.
The EOS 5D Mark II has one CompactFlash Type I/II card slot.

Interpreting the results The data can be sorted by manufacturer, card type, rated capacity, file format and 30-second burst, in both ascending and descending order, by clicking on the appropriate column header. When sorting by JPEG or RAW, the fastest 10% for that format are highlighted in blue. You can view extra information for a card by clicking the icon to the left of the card's name, or for all cards at once by clicking Show Extra Info in the Memory Card header field. All calculations are based on 1 megabyte = 1,048,576 bytes. The word Error in a results field means the card was not able to complete the test and is most likely incompatible with the camera.
