I've been using this 128GB SanDisk Extreme in both my drone and several Eufy security cameras around the house, and it's been rock solid. The speed ratings aren't just numbers on the package - you can actually feel the difference when transferring 4K footage off the drone.For drone work, the write speeds keep up with high bitrate recording without any dropped frames or stuttering. I've shot extended flight sessions in 4K and never had issues with the card choking up or corrupting files. The 190MB/s read speed makes pulling footage onto my computer way faster than the cheaper cards I used to buy.The Eufy cameras have been equally happy with it. No lag in recording, and when I need to pull clips for review, everything loads quickly through the app. The A2 app performance rating really shows - the cameras boot up faster and navigate through recorded footage smoothly.Build quality feels legit too. It's been through temperature swings from indoor cameras to outdoor drone flights and keeps working without complaints. The included adapter is handy for quickly swapping between devices or transferring files.At this capacity and speed class, it's definitely an investment compared to basic microSD cards, but if you're recording 4K content regularly, the performance difference is worth every penny. No more worrying about whether your memory card can keep up with your equipment.

I have relied on SanDisk products for over two decades, I can confidently say the SanDisk 32GB Extreme microSDHC UHS-I Memory Card with Adapter continues the brand’s legacy of dependable performance and thoughtful engineering.The card delivers speeds up to 100MB/s, which is what I was what I was primarily looking for when deciding to purchase. The U3 and V30 ratings help ensure smooth video capture without dropped frames, if I ever wanted to use it for photography.What I’ve always appreciated about SanDisk is their overall quality, and this card is no exception. I've never had an issue with SanDisk products which is why I keep coming back to them.32GB isn’t large by any means, especially with today’s standards, but for the project I'm working on (which requires 32GB max), it's nice to find a company with whom I already am familiar with and trust their products, and most of all that they still make the SD cards in this capacity.

Using them in a security camera indoors, for local storage. No issues. Playback is great. Good capacity. Price is right also for the quality I have been getting

Nice little micro SD Card. I bought this to go with Fiio M21 digital music player. Works well so far, have loaded about 200GB of music on it. 512GB capacity approx. no issue so far with short term use.

Excellent card. My 2TB card works great in my Samsung S10 Ultra, even though Samsung says the max is 1.5TB. Samsung says some users find that some 2TB cards work. I can confirm that this 2TB card does indeed work great. Doesn't even need to be formatted after adding to my SD card slot tray. Add to tray with notch on right side and pins facing you. 😎

I am a big fan of SanDisk. They are my "go to" brand when purchasing flash memory devices. When I first started purchasing flash memory devices I tried a variety of brands. I learned the hard way that some less expensive devices just didn't last, lost data, or did not always read like they should. Once I purchased SanDisk products I just didn't have problems with them. I have purchased SanDisk SD cards, micro SD cards, and thumb drives. My experiences have all been positive. I still have some from several years back that continue to function well. Most important to me is that I find that they are at a nice price point and, as mentioned, work well over time. I use their micro SD cards for my phones (those that still accept them), my security cameras, and my dash cams. I use this specific series, "Extreme" for dash cams. I use the "Ultra" series for my phones and security cameras. My apologies but I am not an expert at doing bench tests on these products. My only experience is actual use. So my gauge of quality is, "Do they work when I need them to?" Unfortunately, the only measure of this is when they go bad, which does not seem to happen with how I use them. As mentioned, I just don't have the issues I had when I purchased lower priced (quality?) devices. I am sure there are some much more knowledgeable reviewers who can report on transfer speed. It would be great to see some of these reports because I have been wondering lately if some of the "higher end" series of micro SD cards are worth the extra price.When I was looking for dash cam micro SD cards, I did a little research and found several reviews that included the SanDisk "Extreme" so I did step up and paid the extra for the "Extreme" series.I also know that I have never had any issues with formatting a SanDisk card.Most of the micro SD cards I order come with an SD card reader. That is nice even though I now have several. That said, I saw that SanDisk also makes a "USB-A" micro SD card reader. The micro SD card loads from the end rather than the side like many of the card readers. I may end up trying one of those at some point. Or, wait to see if they come out with a "USB-C" version.Recommend: YESQuestions: Just wondering if there is really that much difference between the various "series" that SanDisk has for their micro SD cards.
