Lars thank you for taking the time to run these benchmarks.

Consider getting these cards in the future.

For me the Transcend 800x is very interesting. I have seen them on Amazon.uk for a low price

WHICH VERSION OF THE SANDISK EXTREME PRO WAS USED FOR THESE TESTS. THE CURRENT VERSION IS RATED AT 160MBS


Just look at the date of my post. It's from May last year. A long time before the latest Sandisk 160mbs cards existed

I find all these 800x cards from Lexar, Transcend & Sandisk annoying. They're 800x in read but not 800x in write. I much prefer the 600x cards that are both 600x read & write.

The writes of the Transcend are equal to the 64GB 400x cards.

Lexar, Sandisk and Transcend commit to a 120MB/s read but differ in write speeds.

$120 60MB/s = Transend
$135 45MB/s = Lexar
$150 60MB/s = Sandisk

Actual speeds would differ on what device is reading/writing naturally.

I look forward to getting a 512GB 800x card when it is 1/10th the cost at $150 in 5 years time.

That is of course depends whether Canon decides to abandon CF cards for CFast ones.

@ Paolo,

The good thing with the 800x cards is that they usually have a lower price than than both the 400x and 600x cards I buy my cards at Amazon.uk and Amazon.de. Both the Transcend 800x and Lexar 800x are lower priced than their 400x cards. So even if you don't gain much in speed, you get it for free or even at a lower price

Great for you. My only options are US-based shops. The 800x 1/3rd more than 400x.

Sure wish they still sold 600x cards.

Hi guys,
This thread intrigued me, so I decided to do the same test that Lars did. I used my 1Dx, with only one card in the camera (to avoid any possible slowdown by writing to a second card) and these two Sandisk cards....

Shooting parameters:
ISO 100
f2.8
1/60s
Raw capture
Tripod mounted
Basic scene

Card 1:
Sandisk Extreme Pro
32GB 90MB/s
UDMA7
125 frames in 30s

Card 2:
Sandisk Extreme Pro
32GB 160MB/s
UDMA7
148 frames in 30s



Looks like it drops in as #4 in the lineup for speed.

Lars, if you care to add it to the list, that would be great!

I just looked at it. To make your test/result more similar to mine: You should use the same settings. Or at least go as close to my settings as you can.

(my settings)
ISO 100
1/4000 sec
f/5,6
lens EF 24L

It's a rather big difference to shoot at 1/60 sec and 1/4000 sec.

Hey Lar,

thanks for the test. I'm trying to move up from SanDisk extreme pro 90MB/s to something faster.

from your original post, I see some weird things happening or I just don't understand the logic.
Transcend 64 GB UDMA 7 1000x---------156
Transcend 128 GB UDMA 7 1000x ------142

How is 128GB slower than 64GB if it's the same card with just different size? if so why doesn't it work same way with 400x cards? shouldn't 64GB be slower than 32GB?

Transcend 64 GB UDMA 7 400x -----------123
Transcend 32 GB UDMA 7 400x ----------89

I ask because Transcend cards seem to be more affordable now days.

Andy

Hi Andy,

There is no logic When I test cards I will get different numbers even if using five different copies of exactly the same card. There are copy to copy variation when it comes to the speed. And it's like that whatever brand I use. The large difference between the Transcend 64 GB UDMA 7 1000x and the 128GB version also surprised me. Normally the difference isn't that large. But I only had one copy of each card to test.
The Transcend 32 GB UDMA 7 400x is slower than the 64GB version. Every other test that I have seen also show that. The 32GB card is a much older card also. Which I belive is the reason it's a lot slower. I have many copies of both those cards and all copies show this large difference in speed.
The Transcend 64GB 400x card is great value for it's price.

When I did the test I did it 3 times with each card. And then showed the average numbers of those 3 tests. And when I owned many copies of a card, I tested different copies also.

Why did you decide on 800x cards for your 1Dx? Amazon has a good sale on 1000x cards at this moment: 2x 32GB CF cards for $189 - http://www.amazon.com/gp/product/B007DBJ2YE/

The 800x cards have a rather good speed also. Not the fastest but ok for most people. And if you don't shoot any bursts of more than 25 pics the speed will be the same for both those cards

That's true but you never know when you will need that extra write speed, especially when photographing sports or/and nature… and it takes only 2 seconds for 1Dx to create 24 RAWs files

I just found this Lexar 1066x CF card on Amazon: http://www.amazon.com/gp/product/B00IAYFD0K/

Didn't know that they existed Talked with a Lexar representative, and here is his response as for the write speed of these cards:
"Write speed isn't listed, but it will be less than the read speed. Generally about 1/2 of the read speed, but there is no hard and fast rule, as things down to file type can determine write speed." - no comments

Quick google search, and I got this, from Lexar website: "Provides read transfer speeds up to 160MB per second and write speeds up to 155MB per second - Supports VPG-65 for professional video capture" - http://www.lexar.com/about/newsroom/press-releases/lexar-enhances-its-professional-compactflash-line-higher-capacities

Any plans on getting this card for the test?

Go back one page in this thread and you will find pics of the latest cards from Sandisk, Lexar and Transcend. Including this Lexar card

Twenty-eight files, if you're really serious. Fifty-six files if you shoot RAW + jpeg.

I just reproduced this test as close as I could to Lars' set up.



1DX
17-40L @ 24mm
F/5.6
1/4000th
ISO100
fresh battery
manual focus
12FPS (did you use 12FPS or the mirror lock 14FPS?) ..... answered my own question 14FPS is jpeg only.

Lexar 32 GB UDMA 7 1066x ------------156 shots in a 30 sec burst

I did it 2x, got 155 once, 156 once

Another metric I thought might be useful in this thread was total size of the files produced as there was some discussion about if you shot with the cap on making a dark black photo or what your target was, and also to account for the difference in file size made by different cameras. The 1Dx vs the 1D4 for instance.

Anyway in both cases, my combined total file size was about 3.19GB Do the math and that works out to about 106MB/second. File sizes are about 21MB per image.

I have 2 cards. I'm gonna run the test 2 more times with the other card.
