Default CF Card/S400: If 32x not beneficial, is 1x detrimental?

Hi all: I just ordered a Canon s400 so I'll actually have a camera with me (the Coolpix is too bulky for most of the time). I noted Steve's reply to kaps in "Is High End Compact Flash Worth Price for Powershot S400?" was that the 32x write speed was not worth it. I see that many manufacturers offer reasonably priced 1x cards. Will this camera demonstrate noticeable write time lags with this speed? In other words, does this camera have the "internal code" to take advantage of anything over 1x? Thanks. gary tuthill

realize that when you refer to 1x that is a xfr rate of 150KB/sec. now even the slowest card today is approx 4x (600KB/s).

what you have to do is test the various cards in your camera to see when the xfr bus hits the wall or saturates. do a little math (size of file transferred / time(xfr light on to light off in seconds) =approx xxxxKB/sec. there is where you shop if you want the perfomance.

caveat: not all cards react the same way in all cameras. if you know that your going to move "up" in the digital world that cards xfr rate may change on your next camera.

this issue may work itself out in a few generations of camera and cards. sticking with better known cards generally gets more consistant results.

this is fun isn't it ?

Default Memory Performance in the S400

So I guess it begs the question-

Who's going to check out what card is the fastest in this camera?

I guess this question has been asked a lot of time...

Look at it this way as an analogy: Which grade of octane will make my car go faster?
... we have the Yugo and then the Ferrari. One can put the highest octane in a Yugo and it wouldn't go any faster or one can choke a high performance turbo-charged piece of machinery with low-octane fuel... :twisted: :twisted: :twisted:

In most driving conditions no one will notice... ditto with flash cards when used in the jpeg modes !!! :lol: :lol: :lol:

Are there any user databases around somewhere? Other than this site.

Would be nice to have a database site. You input the camera and CF used, then enter the data.

I've seen this done before with overclocked CPUs.

Other than specific camera/users they are hard to come by:
http://webpages.charter.net/bbiggers...rd_speeds.html

Also over here (for cameras that really need the speed):
http://www.robgalbraith.com/bins/mul...e.asp?cid=6007

Most consumer cameras are several magnitude slower, especially when there's no raw(or tiff) mode!!! ie. in jpeg no one will ever see any difference (the camera's internal buffer will take care of it) :lol: :lol: :lol:
