are these SD card results bad?

I recently purchased a new Samsung 128 GB Micro SD memory card EVO SDXC SDHC Class10 128GB SD

I completely wiped it (and my device) then installed it in my Shield K1 tablet and ran a SD card tester and got these results

read: 9.6mb/s
write: 4.1mb/s


seems really bad to me but maybe im wrong?
the package says 48mb/s (i would have been happy with anything close to it)


I also ran H2testw from my pc and got this
