Quality, name brand memory chip for my phone. Works great and is a reliable brand.
Needed a new memory card for my Moto G phone. This works great, was easy to install, and allows me to take all the videos I want of my dog. Lots of memory for the price from a reliable brand, exactly what I was looking for.

CONTINUOUS WRITES AND READS TESTED
I bought this SanDisk 256GB microSD card to use in my Raspberry Pi, and I’ll be honest—I fully expected it to die within a few months. Why? Because I’m using it to constantly record Tesla Sentry Mode footage, meaning it gets written to every single day, nonstop. But here we are, six months later, and this little card is still holding up like a champ. No corrupted files, no slowdowns—just reliable performance. What It Does Well: Even with continuous write cycles, this thing hasn’t slowed down or failed. Perfect for dashcams, security cameras, or Raspberry Pi projects. Holds a ton of footage before it starts overwriting. I can go back days to review recordings if needed. Heat, cold, constant writing—no issues so far. This isn’t my first SanDisk card, and they’ve always been solid for me. One Small Thing to Keep in Mind: Like all microSD cards, it’s best to format it properly before use, especially for high-write applications. Some devices (like my Tesla) work better when you use the exFAT format instead of FAT32. Just something to check before you get rolling. Final Thoughts: If you need a reliable microSD card for constant use, this one is a great bet. I wouldn’t hesitate to buy another for my other gadgets. Just make sure to pair it with a good reader or adapter if you’re moving large files—it’s fast

I have had really good luck with SanDisk products
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 the micro SD cards for my phones (those that still accept them), my security cameras, and my dash cams. I use this specific "style/series" for the phones and security cameras. I use the SanDisk "Extreme" micro SD for the dash cams. 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 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. I do know that I have never had any issues with formatting a card. Most I order come with a card reader. That is nice even though I now have several. Recommend: YES Questions: Just wondering if there is really that much difference between the various "series" that SanDisk has for their micro SD cards.

No more storage worries
With 256GB, my smartphone now holds tons of photos and video without that dreaded “storage full” alert. The up-to 150MB/s read speed shows—after switching some apps onto this card the load-times improved noticeably. I also used it in my Nintendo Switch (older version) and the “Preparing data” screen during game load-up was significantly shorter. The included SD adapter makes transferring files via PC a breeze. If there’s any minor gripe, it’s that the initial format took a bit of time, and the tiny card means you need to handle it carefully when inserting/removing. Overall, very reliable and versatile.

Meets and exceeds the sequential read speed advertised. Works.
Slightly exceeds the advertised sequential reads. Benchmarks are showing ~200 MB/s. Fits and works well, passed validisk and sector scans.
