Review on 📸 Amplim 64GB Micro SD Card, 2 Pack MicroSD Memory Plus Adapter - Ultimate High-Speed Storage Solution for Nintendo-Switch, Go Pro, Surface, Galaxy, Camera, Tablet, PC, and More by Randy Butler

I bought the 2 x 64GB pack that I received but apart from the read/write test I haven't used it. The first picture shows what I used to make the text. The card reader on the top right is USB 3 and pretty fast. I've been using a windows 10 pc with an i9 9900k with a 2080ti etc so the computer is pretty fast too. In the second picture I noticed that I have them in reverse order, so the first test is one on the right. Most on the right took one of the micro SD cards and stuck it straight into the Kingston card reader. if the adapter has a BIG impact on the results (it had NO impact). On the far left is another micro SD card that goes straight back into the Kingston card reader. Now a few thoughts that many SD and Micro SD cards have used (along with an SSD in a computer) over the years. If you're looking for a micro SD card for things like a DVR or home security cameras, I think it's a good idea to look for the V30 on the card.2. I've seen (and it could happen with this card, only time will tell) that "lesser known" brands can experience a SIGNIFICANT "drop" in performance over time. So out of the box they work great, but after a few months they can be almost dead in the water. So to sum up, these cards look great out of the box, but only time will tell if they continue to perform well. I think I'll put one in my dashcam and if I have a drop in performance I'll be sure to let you know.
