A week or two ago, I was trying to record some 1280 x 720 video on my (mid-spec pocket type) camera, and it got badly broken up.
When I got home, I grabbed the SDHC/SDXC cards I could find, all marked C10 and benchmarked them as follows:
(MB/s) Read avg Write avg Write min
Noname 16GB 35.3 10.2 6.6
House brand 32GB 20.6 7.4 3.0
Big name brand 32GB 35.6 22.3 21.9
2nd tier brand 32GB 35.4 16.8 6.2
House brand 64GB 35.7 6.2 4.0
No prizes for guessing
(a) which one was in the camera
(b) which one is now in the camera
So, as I had suspected, not all "Class 10" SD cards have real class.
Now to find something worth videoing...
Cheers,
Peter

Very interesting, did you use some kind of benchmarking program ?

Gnome-disks, just because it's there on my primary laptop (Ubuntu 16.04LTS). It's a bit of a swiss army knife for disks.

Been thinking about that, but I never seem to be able to assemble the courage to actually do it, can't be a jack of all trades n'est ce pas

As an alternative, you can run Ubuntu (and I'm sure many other distros) from a USB stick. Leaves no trace when you're done. (Just don't select "Install"  )

I use Lan_SpeedTest for such testing. Rudimentary, but works on windows.
Helps me to validate my USB3 is working or not (sad to say major driver/chipset issues after swapping hard-drives into a cold spare that was NOT identical).

Thanks, I will add it to the list on Slant !

Wow, the other manufactures are marketing the 'Big name brand 32GB' as V90. 
|

Do you think the benchmarks on your computer apply to using the cards in the camera? Wouldn’t put it past some camera manufacturers to optimize their camera for their own SD cards.
|

AFAIK the camera manufacturer does not supply branded SD cards. Although I wouldn't expect the numbers to be exactly the same, I am pretty sure the general ranking would be similar in different devices.

Well, I have never seen Canon / Nikon / Sony made SD Card.
|
|
|
|
|
Now you have done all this work but we cannot benefit from it as we don't know the makes
Noname is easy though 
|

Obfuscating the brand names is deliberate. My original message was intended as a general comment on the SD card scene, and I don't want to get drawn into potentially nasty and pointless legalistic or marketing debate. In retrospect, I should probably have added "YMMV", although I would expect most CP members to understand that implicitly.

Something went wrong and the new SDK 2.1.401 references a version of the Microsoft.NETCore.App that is on a MyGet feed and should not be in a release. This results in programs that compiled before the upgrade to fail.
You can 'fix' this with a global.json file which pins the SDK to 2.1.400 (the previous SDK version) or by uninstalling the new SDK.
I've made MS aware of the issue, and they are scrambling to rectify the problem, which should not have happened and they admit they screwed up somewhere in the release process.

but they did.

It appears Visual Studio bundled the wrong build of the CLI. @livarcocc's team is working with the VS team to investigate fixes. I'm going to close this as a duplicate of dotnet/cli#9897.
The recommended workaround is to uninstall 2.1.401, download the correct 2.1.401 installers from https://www.microsoft.com/net/download/dotnet-core/2.1, and install those instead.
This appears to fix it, but you may have to do a
dotnet restore -f at the root dir of the solution.

Nope... A MS worker did it. It is nto the same

But that only if you have previously installed the buggy version, or always?

That's exactly why I said that... strange enough... the dev did it.

I had a bug with 15.8.1 and they rushed out a fix that repaired the problem there.
With that one, the resource file plug-in wouldn't load so I couldn't edit resource files.

In 15.8.1 they also broke support for the Italian keyboard layout (fixed in 15.8.2): you couldn't type closing curly braces for the entire month of August I guess it's a good thing it happened in the month during which most of Italy is on vacation!
