Greetings,

A little while ago, TerraMatrix inquired about converting a DSLR into a video
camera.  

In that message thread, I suggested that flash memory speed was one of
the problems that would need to be solved. 

I decided to test my assertion by doing some timing tests. 

I used as a source, 30 jpeg files on my HDD that aggregated about 34MBy
and used Windoze Explorer to copy those files into a new test folder that I
created on each of 3 of my flash memory cards.  The copies were done one
at a time; each test was run twice, and I got the timings by manually counting
off the seconds (thousand one, thousand two, ...).  If that's not sufficiently
scientific, you have my permission to repeat the expirement.  grin

I chose to use 30 files as the source because that would be 1 second worth
of video at 30 frames per second (30 fps). 

These are the (shocking) results ...

Lexar 80x 1 GBy CF Platinum II ... 27 seconds

SanDisk 256MBy CF ... 36 seconds

Transcend 1GBy SD ... 13 seconds

As you can see, the flash memory I own isn't anywhere near fast enough to
record video at 30fps. 

If anyone has (or knows of) faster flash memory, I would like to know about it.
