I like the added space and speed of these cards.

Provides great transfer speeds and has plenty of room for video.

However the write speed is quite a bit slower

Speed seems very good and has not been an issue.

Slow write speeds

Fast speeds, low price and very reliable

This card is compatible with my IP security camera, the write speed is good and I am able to watch playback on it without any issues

Speed was also much slower than advertised.

This is supposed to be a UHS-1 card, but my phone requires UHS-1, and on installation I got a message saying its speed (80) is too slow

Good transfer speeds and nice price.

Good writing/reading speeds.

It meets &/or exceeds its advertised speeds.

Speed of this microSD doesn't matter much for normal applications, like taking photos or recording standard HD footage

I don't test read write speeds like some do

Fast transfer speeds, Sony brand

Works well and has excellent transferel speeds

Great quality and speed.

good timing ,good speed good product ,highly recommended

Good transfer speeds.

79MB/s is respectable and slightly above manufacturer's spec of 70MB/s
