Review on πΎ Kingston 8GB Class 4 MicroSDHC Card Flash Memory - SDC4/8GB (Includes SD Adapter) by Linda Diaz
Slow, does not run at Class 4 speed
Disappointed as I have usually liked Kingston products. But this SD card is out of specification. It's class 4, which means it must write at least 4MB/s. However, the best this card can do is around 2.5-3.4 MB/s. It only touches 3.4 after a long climb. I have a non-class Sandisk that blows it out of the water at around 5.5MB/s. Testing uses the same file, same adapter. The numbers show this when transferring files via Windows 7 AND when testing with the H2testw program. After searching, it turned out to be an issue with some other Kingston Class 4 cards. Speed is important to me as I'm running it on a tablet and it lags when the card isn't good.
