[Gigastone] 512GB Micro SD Card, Gaming Plus, MicroSDXC Memory Card for Nintendo-Switch, Wyze, GoPro, Dash Cam, Security Camera, 4K Video Recording, UHS-I A1 U3 V30 C10, up to 100MB/s, with Adapter

br>br>The capacity of this "512GB" version was "500GB": 465 GB of data, 500,259,749,888 bytes It doesn't seem like much, but why can't they just say it's a 500GB card in the description?br>br>I feel like they're taking advantage of naive users who gloss over the big digits and assume it's the standard decimal? The difference in binary conversion.

I bought five cards and spent hours trying to get them to work on different devices. The SD card isn't recognized by Windows or any of the other programs I found on the internet, and it can't be formatted. Please provide information on how to make this disc usable, as well as a reliable method of formatting it so that it does not appear as "write Protected!" all of the time.

I was a little skeptical when I bought the 512GB Gigastone MicroSDXC card, but it's the real thing. With FAKEFLASHTEST v1, I was able to pass all of my tests. H2testw and 1 are two different types of tests. In Crystal Disk Mark v8, the card achieved read speeds of 98MB/s and write speeds of 59MB/s. It has a score of 0 and is considered to be in the middle of the pack. Although it is faster for reading than the manufacturer's claimed speed of 80MB/s, it is slower for writing. YMMV, as this was only a single test with a single card reader on a single card. br>br>This is one of the better options for purchasing a genuine large capacity card with "OK" speed.

2019- This is for the five-person team. UHS-II cards in a pack 1 microSD card is included. I checked each one after receiving them and found them to be fully functional. They're quite quick, as evidenced by other people's test results, which are very similar to mine; all five cards I received performed similarly, if not identically. They're fairly good for the price. However, I am unable to comment on the long-term viability at this time. I'll let you know if one of them fails. Aside from that, they've earned the five-star rating.

We haven't had any problems with our phones getting wet. These micro SD cards were used to save photos that my boyfriend and I had transferred to them. Both of us are missing photos after having them for a month. All photos were taken before inserting and transferring files to the SD card (as recommended by Verizon). All photos taken in the last two years (20-). Up until the day we installed the SD card, we had 40 GB of free space. Every two weeks, we checked to see if the SD card and previous photos were still in our phone. We're not sure why our photos are missing from these micro SD cards. Our cellphones are no longer able to recognize us. With the SD converter, it is no longer recognizable to my laptop. If you want to keep your files, I would avoid using this product. It's only been 6 weeks since we tried these. a huge letdown!.

I ordered these because they seemed like a good deal (5x 64G), but when I tried to copy files to the first one, it kept reporting that it was write protected. I tried a variety of computers/laptops/devices, as well as different adapters, but I couldn't get it to write data. I eventually gave up and moved on to the next one in the pack, where I had the same result. The next one I tried immediately worked, so I tried the last two and only one of them worked, giving me a 3 out of 5 failure rate. I ordered a replacement from Amazon, which arrived the next day, and tested all five cards right away, finding only one that was write protected. Still a 20% initial failure rate, but I'll keep one of the original working cards and send back 4 bad cards along with a single good card to Amazon. br>br>If any of them fail in the next few weeks, I'll spend my money on Samsung or SanDisk, which I've never had a problem with.

I've had my share of bad luck with low-cost options. ish cards on Amazon, which failed testing (typically by spoofing the reported capacity vs. the actual capacity). As a result, when I came across this 5-minute video, I thought it was worth sharing. I was sceptical when I saw a pack of 64 GB micro SD cards. Thankfully, all 5 cards passed F3X testing, which included a 2-hour write test and a 1-hour read test.

So far, our security cameras have worked flawlessly.
