2. Lexar 32GB 1000x (LCF32GCTBNA1) UDMA7 - 150MB/s read / 95MB/s write rated
23 frames until buffer full

Strange, both of the 32GB 1000x Lexar cards I have will do 32 - 33 frames before slowing down on my 5DIII.

(I'm assuming by 'buffer full' you mean when the continuous frame rate drops from 6fps.)

Same for me.

Lexar 1000x will go to about 30 before slowing  down on my 5d3.

Hmmm, will have to try the test again making sure noise reduction, ALO, and such are off when I do it, but yes, I hold down the shutter on high speed until it slows and count all but the frame.  I also noticed that the 1067x card keeps shooting at a higher speed (maybe 3fps vs 1fps) once the buffer is full.  Will play a little more and post results.

I just ran it again three times with all settings turned off and just the body cap on the camera shooting RAW - 23 frames on the 1000x Lexar, 35 frames on the 1067x Sandisk.  This is the number of frames on the 5DIII before it begins slowing from the max frame rate.  Yes, you can keep shooting at a reduced frame rate and eventually it will slow even further, but I'm measuring (and interested in) the number of shots at full frame rate. 

Also, given these results, I can confirm that aberration correction, vignetting removal, and standard levels of high ISO noise reduction don't impact frame rate.

I did a more controlled test this morning.
Settings were, camera in M mode, 1/8000 sec, ISO 100, f/2.8, AF turned off on lens, RAW capture only.
I held the shutter down to capture 78 frame in high speed continuous AF drive mode.

I then extracted the capture time, including the sub second time value, from the EXIF into a spreadsheet.
(Note the camera only captures sub second time accurate to 10ms intervals.)

For frames 2 - 78 I subtracted the capture time of previous frame to measure the shooting speed.

Results:
- frames   2-30 = average capture time 165ms, min time 140ms, max time 170ms - FPS 6.05
- frames 31-78 = average capture time 287ms, min time 200ms, max time 410ms - FPS 4.02

I'm not sure why your Lexar card is slowing down after 23 frames - perhaps a low level format might help.

mack..I didn't leave the body cap on, I shot at a a fixed subject - large RAW - I'll also try it again and check back.   do you have image quality set at "10"


interesting...

edit...I wonder if this is the reason for the diff....from Adorama website:

Lexar Pro 1000x 16GB UDMA 7 CF Specifications
Capacity   16GB
Read Speed   1000x (150MB/s)
Write Speed   Max 966x (145MB/s)
Compatibility   UDMA CF and CF devices

this would mean that there are two different lexar 1000x cards, both at 150 read, but with 95 and 145 write.

Yes, that would certainly explain it!  I bought my 1000x card in November 2012, and it's the old 95MB/s one.

AFAIK the 16GB card was rated at 95MB/s max write speed; but the 32GB and above were rated at 145MB/s max write speed.

Perhaps there were some slower 32GB cards released.

yes...but the link i posted is for a 16gb lexar 1000x with 150/145?   

to add to the confusion, I'm pretty sure my lexar 1000x 16gb is 150/95 (from BH photo)

with that said, i'm still pretty sure it shoots at 30ish fps before slowing. 

(after rereading what i wrote earlier i realize that the question about RAW image quality setting was N/A)

Another factor that may affect the result is average RAW file size.
For the test I ran this morning the RAW files were all roughly 21.8MB (the lens cap was only so they are all just dark images).

If you're files are significantly larger then you would probably fill the buffer sooner.
I've seen RAW files up to 36MB, so the number of frames before the buffer fills could vary quite a lot.

mack...i think something is wrong with your card or 5d3 settings if you're only getting 23 shots before slowing.  i did this simple test a couple weeks ago and posted results comparing the lexar 1000x and sandisk 90mbs with 45 write speed....both went to about 30 shots before slowing on my 5d3.

i wanted to point out to people with a 5d3 that my upgrade didn't make any speed difference in write times....or read if using USB 2.

check it out.

I checked my order and here's the Lexar 32GB 1000x card I purchased from B&H and it says 95MB/s write speed - so I guess they made 2 different ones: http://www.bhphotovideo.com/c/product/841566-REG/Lexar_LCF32GCTBNA1000_32GB_CompactFlash_Memory_Card.html

This is the motto of the British Special Air Services (SAS), their special forces / Navy Seals, and when I was a kid, I spent a few years in England and learned about the phrase.  I always thought it was really cool, so I've made it my personal motto as well.

I read your thread and the interesting thing is that my Sandisk 32gb card (which looks just like your 16GB card is rated for 90MB/s read AND write speed, not 60MB/s.

Also, so we're all on the same page, my test was done like this:

Camera settings
-5DIII with battery grip - 2 fully charged batteries (grip doesn't matter)
-Freshly in-camera formatted CF cards
-ISO 100, 1/8000s, body cap (so f/0, manual focus)
-ALO, High ISO NR, vignette removal, CA correction OFF
-RAW
-High Speed Drive

Test
-Depress shutter fully until the camera slows
-Wait for buffer write to finish
-Press image review - look at # of images, subtracting the extra frame that indicated the buffer was full

Results
-Sandisk 60MB/s write: 19 frames
-Lexar 95BM/s write: 23 frames
-Sandisk 90MB/s write: 25 frames
-Sandisk 150MB/s write: 35 frames

I realize that the body cap photos are all black and real photos will be larger and slow the camera more, but I think that this is the only way to have a 100% reproducible test.

Unfortunately, I think all we've really accomplished is confuse everyone  :)

Are people testing write speeds with single or dual cards in place.

It’s always been my understanding that when writing to dual cards using a 5D111 the speed was governed by the SD card. Putting in faster SD cards made no improvement. But this limitation does not apply to the 1Dx.

Can anybody confirm this?

The way I read it... they are only putting one card into the body... a cf card.
