How fast must a CF be to save 2560x1920 TIFF?

Question

I have an Olympus E-20P which is 10 years old with a 256MB CompactFlash card.

It won't let me choose 2560x1920 TIFF, so I assume that my CompactFlash isn't fast enough.

Are there any rule of thumbs for what speed is needed to save 2560x1920?

Update

According to the manual:

  • RAW, 2560x1920, ~10MB
  • TIFF, 2560x1920, ~15MB
  • SHQ, 2560x1920, ~3.9MB
  • HQ, 2560x1920, ~1.5MB

When the camera is powered on it selects HQ, and even if I choose TIFF, it won't change.

So I suspect that it is my "Sandisk CF SDCFB-256" with 3.6MB/s that is the problem.

Answer

I happened to notice this from the FAQ I referenced in the answer to your last question:

Question: If I purchase a high performance CompactFlash card for my E-10/20N, will it reduce the time writing to the media.

Answer: No, the writing time is controlled by the camera, not by the Media.

In other words, it won't help.

(This mentions the "N" version, but as I understand it the only difference is video out format, NTSC vs. PAL.)

And this review say that this camera can only save TIFF in 2560 × 1920 — so something else is going on.
