Sounds fine, check the capacity though as many fakes are small ones with firmware to make it say its larger (IE: a 2GB card that firmware says is a 32GB and will error on anything over 2GB)...

The speeds on the packaging are usually peak speeds meaning that it can go as high as that.
Sustained speeds are always lower

You should do a 'Write+Verify' test in H2testw on 'all available space'.
Get the newest version as well, 1.4

You not going to believe but so weird.
I run again. Same program same setting. No update.
Warning: Only 488090 of 488092 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 72.6 MByte/s
Reading speed: 76.6 MByte/s
H2testw v1.4
Not sure why this time say 1.4. Maybe I go crazy.

I would put the memory card in the device you want to use it in and format it with the device and see if run into issues. If no, pull the disk out and run the memtest again. If you still run into errors, return it/exchange it.
SanDisk does have their own tools on their site you can use for formatting and testing, might be worth looking into it. I think they can even identify if the disk is theirs.
