this would mean that there are two different lexar 1000x cards, both at 150 read, but with 95 and 145 write.
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.
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
mack...by the way, i've heard "he who dares wins" about a million times in the past few years...do you know what I mean by that or did you just like that quote?
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.
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 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
-High Speed DriveTest
-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 fullResults
-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
