This is an excellent card. Bought for my note 9 to increase storage as I take lots of photos. Very impressed with its speed when transfering from card reader to my PC. Also looks to be made super tough. Highly recommend it if your planning to increase your smart phone capacity. Just please make sure that your phone supports higher capacity memory cards
There's really not a lot to say about a memory card. It's big (and tiny), it works, it's pretty fast, but it had better be for that price. The packaging is terrible, expect to curse at the blister pack with frustrating "open here" instructions where it's clearly been hermetically sealed. But once you've got it out and in your device, it's pretty much something you can forget about. Good, not great - perhaps great it if still works in 5 years, which I hope it will.
Arrived in time as stated. Micro-SD cards are working. But it said 30Mb/s writing speed. I trasferd 4Gb of data to one of the sd cards, using the laptop's sd card slot. I checked the speed during file transfer. It reached about 27Mb/s at a few instances. Most of the time it was writing at speed of about 200Kb/s. So the writing speed was changing from about 50Kb/s to 27Mb/s. I am not sure whether this speed change due to the nature of the file.
