SD card speed

[Phan__]

I just bought this SanDisk Ultra MicroSDHC card said speed upto 80Mb/s but when i test it on my phone it reported with read 49Mb/s and write at 13.65Mb/s. I cant read it with adapter on my laptop either just through phone. Any idea ? Did i buy a fake one ?

Sounds about right on a phone, most can't break 30mb/s so your speeds sound just fine.

For laptop, are you sure that:
1) The card is SDHC and not SDXC
2) Your laptop handles SDHC (or SDXC )
