Review on 💾 Premium Kingston 4 GB microSDHC Class 4 Flash Memory Card - Reliable Storage Solution by Ada Jankowska ᠌

I have 2 such cards, one was bought 2 years ago, and the other a month ago. the latter is better at writing small files, while the speed of linear writing / reading is almost the same. Write speed 10.8Mb / s, read 18Mb / s (this may be a limitation of the card reader) I checked it on a non-name card reader and on a transcend, the indicators are the same. Added on 02/23/2022: Recently I bought another one of the same, its speed is no longer 10Mb per second, but 4.5Mb per second ((( : I am describing an 8GB card, others have different speeds.
