The 128GB x1066 are rather cheap but I seem to remember that they were less stable than the x1000?

Maybe quite the opposite and this issue has been solved. http://www.magiclantern.fm/forum/index.php?topic=7264.msg61467#msg61467

Yes, there are problems using devices > 127.5 GiByte (1 GiByte = 2^30 Byte) with Windows 95.

Hi guys - new here - been shooting panosheres for a few years now - shifting over to video -

About SD cards - how can I test them?

Ideally I would like to shoot some Video on my trusty EOS 650d - and I have seen this
Lexar Professional 64GB microSDXC 1000X 150MB/s Class 10 UHS-I U3 Memory Card

Can I test the write speed - 150 MB/s is the fastest out there I think...

TIA

UHS-I with 150 MByte/s? Link please ...

Kind of off topic, but for anyone interested, there seems to have been a minor price drop on the 128GB 1066X KB cards on amazon.de
Amazon.de =79 Euro (85USD)
Amazon.co.uk = 75 Pound (107USD
Amazon.com= 93 USD
Apart from being way cheaper than eBay, 85USD is by far the cheapest I've ever seen these

5D3 1.2.3 on SanDisk Extreme PRO 64GB (1067X, 160MB/S)

David IV · « **Reply #133 on:** February 01, 2016, 05:33:53 PM »

Hello this is my benchmark with 128gb Komputerbay 1066x on Canon 5d2

And this is not enough to rec 1856x1044 RAW
What I should do? Ask for a refund? It is not too slow?

Walter Schulz · « **Reply #134 on:** February 01, 2016, 05:49:53 PM »

The best USB 3.0 cardreaders will give you about 150 MByte/s in write mode for this card. Cam's card interface is the bottleneck in real life.
You may see slightly higher numbers by pressing PLAY button after starting benchmark. It will show you what the cam is able to do but not what you can expect during recording. Overhead ...

David IV · « **Reply #135 on:** February 01, 2016, 07:06:43 PM »

Ok I understand this point but I thought at least be able to rec with this card 1856x1044 continuous. So the problem is the camera can't afford this amount of data or I could get this video resolution with other faster card?

Walter Schulz · « **Reply #136 on:** February 01, 2016, 07:15:44 PM »

This one is among the fastest cards you can get. I repeat: The cam's card interface is your bottleneck.
Shooting continuous with 24 fps in this resolution requires about 77.6 MByte/s and you won't be able to match the numbers.

reddeercity · « **Reply #137 on:** February 01, 2016, 07:43:43 PM »

75MB/s is the limit the 5D2 can sustain , but can record in busts to 79MB/s for about 20-30 second
the only way is to use .raw (legacy raw no audio & metadata) should be able to maintain 1856x1004 @ 23.976p A.R, 1.85:1
At Least from My 5D2 on Lexar 1000x & 1066x tests show

If you what audio then you need to choose a smaller frame resolution
I use 1856x928 for long recording & scale it to full HD if needed

David IV · « **Reply #138 on:** February 02, 2016, 03:27:15 PM »

I can go with the same resolution sizes. Thanks Walter Schulz and reddeercity! Seems work perfectly!

HappyBlack · « **Reply #139 on:** February 03, 2016, 08:23:05 AM »

If so, is there any sense in buying Lexar 1066x over Lexar 1000x for my 7D?
I understand 1066x has slightly better write and read speeds, but almost all benchmarks are made using 5D3, which also has higher write limits.

My point is: will 7D benefit from choosing 1066x at all?

I'm aware 1000x is no longer produced, though sometimes still available at the market.
I can get 32GB 1000x in the price of 16GB 1066x.

Thanks.

HappyBlack · « **Reply #141 on:** February 04, 2016, 08:03:46 AM »

Wow!
So the oldie 7D can go a little faster than the suggested 80MB/s in the ML RAW Capacities charts.
No point in saving money on CF card, then.

Thank you very, very much.

Just for reference, I completed this benchmark on a 650D some time ago...

SanDisk Extreme Pro 256GB 160MB/s 1067x. Canon 5Dmark3 1.1.3. Card reader Transcend TS-RDF8K USB 3.1/3.0 and TS-RDF9K USB 3.0
1920x1080 continue writing MLV with sound - on and GlobalDraw - on. 46,8 min recording.
VERY interesting: "Busy" is flashing on small upper display from 0 until 9min.45sec. and impossible to change Av or Tv. After this time (9min.45sec) "Busy" disappear and it is possible to change Av and Tv. But if you press autofocus button - "Busy" is flashing again.

I've read a lot here and through the web and I'm far away from being through. I know that many aspects influence the actual write speed during shooting. However, to boil it down to one question:

would you recommend 64GB Sandisk Extreme Pro 160mb/s or 128GB Sandisk Extreme Pro 160mb/s? Is it worth to get any of these if the camera can't keep up with the cards writing speeds?

The benchmarks in this thread show similar speeds:

http://www.magiclantern.fm/forum/index.php?topic=12630.msg144584#msg144584 vs http://www.magiclantern.fm/forum/index.php?topic=12630.msg164489#msg164489

No card really topped the 100mb/s in writing speed since it seems that the bottleneck is the camera itself?
Then I read that the 128GB is »the best« in terms of writing speed with the right settings of course.

Anyway, ML tells me that I need at least 104mb/s for the resolution I want. I've tested with my KB 64GB cards and they stop after 5-10sec. Writing speed in benchmark are about 90-92mb/s.

Did anybody had the full writing speeds or at least over 100mb/s with the fastest Sandisks or Lexars?

Thank you!

jimmyD30 · « **Reply #145 on:** July 19, 2016, 09:08:41 PM »

The bottleneck is the camera, limit is around 90MBps, so a fast card is needed. But you won't get 104MBps needed for continuous recording of the resolution you desire, yet you can get small amounts of recordings like you are experiencing, this is normal behavior.

dutchfilms · « **Reply #146 on:** March 26, 2017, 10:35:41 PM »

Hello, please pardon my ignorance or lack of technical knowhow but I've just installed ML on my 700d. I have a Sandisk Ultra 80mb/s card but could only get lowest quality constant raw video to record. Anything decent would record abbot 5 seconds before fail.

I then bought a Sandisk Extreme 90mb/s class 10 v30 64gb thinking this would work but it still only gives me a few seconds.

I don't understand all these black screenshots of benchmark tests, which card speed will work for me?

Thanks

Walter Schulz · « **Reply #147 on:** April 05, 2017, 07:00:36 PM »

Interface limit for 700D is about 40 MByte/s. Card needs to be formated with ExFAT option. Cam should do that on its own for cards > 32 GByte but you should check that using your cardreader.

And without running benchmarks you are not able to tell if the label tells the truth. Flash fraud is widely spread.

spe42 · « **Reply #148 on:** June 11, 2017, 09:56:36 AM »

I understand that the "bottleneck" is the camera as far as write speed, but I wonder, can someone explain to me if this is solely a hardware limitation, or if there is potential room for improvement via ML? Thanks.

Walter Schulz · « **Reply #149 on:** June 11, 2017, 02:23:49 PM »

Theoretical bandwidth limits for SD-card interfaces (UHS-II excluded):
http://www.hjreggel.net/cardspeed/cs_sdxc.html
For 700D it is 47.68 MeByte.
5D3 is using UDMA-7 CF-card interface and that will do (theoretically) transfers up to about 159 MeBytes.
