Is 1066x CF card a waste in a D800?
Mar 15, 2014

Does anyone know the maximum read/write speed of the D800?

I have a D800 and shoot 14-bit RAW bursts of sports and also video.
I want the newest/fastest memory card available, but don't want to waste money on a card that is faster than the camera.

Lexar's recently introduced their 1066x CF card with:

  • 1066x Speed Rating
  • Max. Read Speed 160 MB/s
  • Max. Write Speed 155 MB/s
  • UDMA 7 Compliant

Lexar's next step down is 1000x:

  • 1000x Speed Rating
  • Max. Read Speed: 150MB/s
  • Max. Write Speed: 95MB/s
  • UDMA 7 Compliant

My question is, would a 1066x card be wasting money in a D800?
Is the D800's processor fast enough to justify the higher cost of this new 1066x card?

IOW if the D800 can only read/write around 95 MB/s then a cheaper 1000x CF cards will work identically in a D800.

I realize Lexar now has a 3333x CF card but I'm not even considering that card. $$$$$$

Also this is not about 'compatibility' as in, "Does a 1066x card work in a D800?"
I'm virtually certain it will work since Lexar's website says the 1066x CF is compatible with the D800.
FWIW, Nikon has tested only up to 1000x and I think they only test new cards about once a year.

But "compatible" is not the question.
The question is similar to, "What is the speed limit where I drive and should I pay a fortune for a car that can go much faster?"
Sure, you can pay $300,000 for a Ferrari and only drive it 55 MPH.
The Ferrari works fine at 55 MPG.

Does anyone know the maximum read/write speed of the D800?
