I have been using San disk memory cards for a long time but it has never lived up to my expectations, its not at all durable and cannot be trusted with all the data, its not at all durable.
San Disk Memory cards really do preferably well in its 8 GB variant but not at all in the 16 GB variant, the card gets corrupted in its 16 GB variant as big chunks of data gets stored in it.
Sadly I bought its 16 GB variant online, as soon as I inserted in my smart phone, the smart phone indicated that the memory card is corrupted, I replaced it with a new 16 GB San Disk Memory card still the same problem persisted.
I wont recommend this memory card at all.
