Lexar 1000x Read/Write speeds Issue

[renteriafilms]

Hey guys, so I decided to jump on the 5D RAW train. I've got a 5D Mark II. I bought a Lexar 1000x 32GB CF, and decided to do a few benchmark tests, to see if it showed speeds at around the "guaranteed" transfer speeds at 150mb/s. After multiple tests, I am averaging between 55-65 write speeds, and between 70-80 read speed. Is it just me, or is this really low for this card? I was expecting something at least over 100mb/s. I've turned live view off, turned off the raw photo, and the global draw is off. Is their something that I am missing? Or does it sound like a defective card? I can record in the highest resolution for about a minute, until it automatically stops. If anyone could help me out, that would be great. I'm new to this stuff so any tips would be awesome. Thanks in advance!

and what is "the highest resolution" that you said you recorded only for a minute?

1880x1058

that resolution is not sustainable on the mkII. Try 1856x928 or 1728x972 16:9 . They should be good.

How far of a upscale have you taking those resolution up to? Your experience how long is your average take or shot, I'm thinking the average is about 5 to 10 sec? 1856x928 or 1728x972 16:9 is continuous right?

Pish posh, I have been doing 1856 x 1044 continuous (raw_rec) since last year.

Your mileage may vary though.

To the OP, remember that the advertised speed is always READ speed and not write speed, unfortunately.

Both are continuous. That is, around 15 min on a 64 gig CF. Average would vary depending on subject matter. I took it to my son's concert and shot the song performances with raw. It held up ok.

I'm talking about MLV + sound. For raw rec, its higher.

This information doesn't really help. I'm trying to figure out if my card is defective, not trying to figure out which resolutions work with my 5D2.

No that sounds a little low for a Lexar, I have 2 Lexar 1000x cards
32 & 64 GB . I see write speeds around 72-78MB/s in Crop mode.
And around 63-69MB/s in non crop mode, for comparison 
With mlv format with audio I can capture about 1000-1200 frame
At 1856x1004 23.976p & 1872x936 is continous , without HDMI device.
If run the old raw format , from Oct24th  from a.d.'s 5d2 builds
I was able to get @ 1872x1250 23.976p for about 1000-1200 frames
I don't judge my cards by the benchmark, but buy the largest frames size
I can do for the longest time .
The bottleneck here Is the CF Card controller , I never seen or heard anyone
Getting better then 78MB/s on the 5D2.

Thanks for the information!

As said before your mileage may vary but I have seen several people post speeds over 79MB/s with raw_rec, including myself.

What is your average speed of your card? Also, if I were to put my card into a 5D3 with ML, and then do a benchmark test, would the speeds be faster than benchmark tests on a 5D2?
