Compressed lossless vs. uncompressed speed
I don't recall seeing this posted so for your curiousity...
I was doing some timing tests for something else, and decided to experiment with uncompressed speeds.
Setup: Two cards, one 45mbs and one 60mbs, in backup mode, shooting a 15 shot burst, and timing from start of burst to green-light-off.
I have seen speculation that the compressed takes processor speed, may slow things down.
Compressed lossless 14 bit: 24 seconds
Uncompressed: 54 seconds
More than double!
It's all about the data size apparently, the compression itself is completely overshadowed by data write time, at least in this configuration.
