What is the best MicroSD card to bye Sandisk ultra or Sandisk extreme?

[Skov]

I have looked at: 

SANDISK MICROSDXC ULTRA CLASS 64GB with read/ wirite of 30 MB/s

and SANDISK MICROSDXC EXTREME UHS 64 GB with read 80MB/s wirite 50MB/s

Does this make an differnece, on my experia z1 ? Does z1 support the high speed ?

the Xperia Z1 can support Class 10 memory and in fact does very well with it. So yes you can go ahead and use that card. However there are even higher speed cards that go to higher transfer rates than 30MB/s.. Those however might not be fully harnessed by the Xperia per my understanding.

which class is the best? 10? or the less ones?

[Skov]

10 is the best, but the new good cards (the ons I mention) are faster then the best class Standart.

Yes i know the ultra ones or extreme....but the ultra ones 32gb class 10 30mb are here more cheaper than the regular 32gb class 2..i dont understand why? I'm confused..

what's the difference between just SDHC and microSDHC? Both compatible for xperia z1?

The microSDHC are more expensive i see now...

[Skov]

Never bye a class 2 card. I can se why yoy are confused by the price difference between the ultra one and the regular. But it is just a mater of the ultra one are more popular, så there is more competition in the market. 
Ultra one is a much better card then a regular class 2 card.

As of the SDHC and microSDHC. The only card that can fit in the z1 is microSD. http://upload.wikimedia.org/wikipedia/commons/a/a7/MicroSD_MemoryCard_002.jpg

In the picture you can se the different size of SD cards. SD is the largest, then miniSD, and last MicroSD.

But there is microSDHC and microSDXC cards, z1 can handle both. HC uses the filesystem fat32 and have a maximum capacity of 32GB.
XC uses exFat filesystem and can have af capacity of maximum 2TB.

Ever done a speed transfer test ?

I doubt the Z1 or any mobile device can transfer faster than class 6 speeds. Video cams or DSLRs can do better.

Thing is you cannot get a 64GB card in class 6. It only comes in class 10.

Going for extreme or anything faster is a waste.

The class depends upon your needs.  A class 10 microSD card is great if you're only using it for music, photos, etc... but if you're looking to use your card to store apps or in conjunction with apps that need to randomly access multiple files rapidly the lower class 2 & 4 cards are better because they offer superior random read speeds. 

So in short:

Class 10 for media storage

Class 2 for Apps2SD
