Amplim Extreme High Speed 512GB Micro SD Card - MicroSDXC U3 Class 10 V30 📸 UHS-I TF with Adapter: Ideal for Nintendo Switch, GoPro Hero, Surface, Galaxy Phone, Camera Security, Tablet Review

Not as good as expected but still very good, all that matters is the write speed of 58MB, which is 464MB/s. Enough for Gopro 7 black 4k 60p or OSMO Action 46 60p. I prefer the Samsung EVO with the same specs.

As you can see from these photos, uninvited guests visited my farm for several nights. I couldn't find out where that cow came from until I got you my infrared wildlife camera. Several neighbors have lost their cats; including one of mine. Now I know that we, the coyotes, come into our gardens after midnight and eat our pets. This SD card took clear photos of the beasts.

Previously bought a few other SD cards from other manufacturers before stumbling across this gem. Others succumbed, became corrupted, or had trouble communicating with them. However, this little gem doesn't have that problem and is all I buy now. The price is quite high and it takes forever to fill the vault. Right now I have three: one for my tablet, one for my phone, and one for various things when I need to transfer crap from one laptop to another (when my passport isn't available).

Something didn't work right from the start. Read/write speeds weren't as good as the specs said, but they were close. I noticed that the more I used the card, the slower it got on both reading and writing. Finally after 2 months it just stopped working and I lost data on it. I reformatted it and it stopped working after 12 minutes of video recording. I'm afraid to use it in anything critical. I'll update this review if anything changes for the better, including a warranty replacement if there's

I know you'll never get the full 512GB but I have about 480GB so where did that 32GB actually go? I've had others from different brands that never used 32GB. I had a problem when trying to use it for the second or third time. I use it in my surface GO the first 1 or 2 times when it is recognized normally and I can write and read on it. Either the 2nd or 3rd time it wasn't seen by Surface GO. Reboot and everything is fine again. It hasn't happened since, but I hope it doesn't indicate an error…

This card is perfect. I opened the package, installed it on my Windows 8 laptop and reformatted it without the "Quick Window Format" checkbox. The format processes byte by byte and took 8 hours to complete. but it was passed with honor. Excellent work. I've bought a lot of cards in the past and the first clue is when Windows says there's 256GB available on a 256GB card. YOU fail every time. But the Amplim Card reported 240GB and I was relieved. I really found a WINNER. I will enjoy this map…

I gave this device one star for its rating and value. The reason is that it was an expensive card. He was super fast too. I bought it for my Go-Pro 8 and a trip to Alaska. I recorded about 2 hours of video, photos, 4k videos, flashes, etc. Everything looked fine. The last video I shot was at the airport leaving Alaska. No problem, right. I come home, turn on the camera and it shows a map error. You have to format the card to recover it, but you will lose all your data. There really are no words
