For my dashcam, there are precious few "compatible" brands of microsd cards. Others behave strangely or cause the auto-overwrite functionality to not work correctly. At first I thought it was just the cam firmware being crap, but I didn't realize there could be such variance in the quality of these cards.

same here - similar issues... bravo to the poster for sharing the findings!

Before my eyes reached the domain name, I thought "is this a bunnie article?" Is anyone else doing [publicly available online articles on] investigative research on electronics like this?

Oona Räisänen writes some remarkable stuff. Not maybe so much about manufacturing and quality of electronics, but building and reverse-engineering stuff. I've been baffled time and again by her talent.

I follow Gough Liu's blog [1]. His investigations on power banks[2] was especially helpful to me. He covers many other gadgets too.

Thanks. I didn't realize this was 5 years old when I posted it, I just saw it on Twitter today.

Like with Fabrice Bellard, the amount of knowledge that bunnie has is absolutely mind-blowing and amazing.

At some point, if Fabrice and Bunny go into a startup together I will give them any amount of capital they need up front to get going :-)

Seriously someone close to them needs to convince them to set up a patron account at patreon: https://www.patreon.com/ Then post the news here. Patreon is a simple way to auto send money to someone that creates work you admire ($1-5 typical once a month) so they can keep on creating.

One notable change in today's market: Samsung flash memory cards are available at retail now under their own name.

For the life of me, I have not come up with a sane solution for this issue. On my 2013 MacBook Air, It keeps hitting the lock switch when I insert an SD card. MicroSD cards are often used by myself and my team, and put into card bigger card readers for consumption. I don't care too much for regular sd cards, but I acquire media in the field ALOT, and need to get quick access to pics and vids for editing on the go. I don't want to purchase a USB SD Card reader. Does anyone have a sane solution or experience addressing the issue?

It sounds stupid, but scotch tape on the lock switch really helps.

It was my 'fix' when one of my readers had a broken lock detector arm, and read all cards as locked even if they weren't. The scotch tape on the card fixed it :)

It does not sound stupid. It's the standard thing to do.

Here you really need to have a thin tape, Scotch cellotape is fine. In other places, the good old duct tape saves you. (We actually call it "Jesus tape" here, because it saves people.)

I also got a fake Kingston USB Data Traveler G3 from a local shop. I had an old one (still G3 though) but the material are different. Some parts a rubberized, and there's an activity LED, while the recent one is all glossy plastic, and no LED.

@dang - can we get [2010] in the title

I updated it
