Initially I get a write speed up to 9Mb/sec for large files and on average 7Mb/sec for any kind of multiple files whereas SDHC class 4 card can only give u a max of 5Mb/sec. You will surely notice a significant performance boost up for media contents and opening up large files We get around 14.8 GB, but after use of 6 month’s I dont know why the performance of it detoriates which really dishearted me
cons
1) Not that fast speed
2) The free micro to SD card adapter is quite ordinary.
3) The card get slow after 6 months of usage
4) Not easily detected with my pc
Conclusion: If you are one who are regularly using your smart phone as mass storage and you want an good storage solution for your phone than go for other’s brand, So I would never ever recommend you to buy this product
