I had talked to the customer support of HTC regarding using class 10 ,16GB sd card. They told me that you cannot use class 10 card on wildfire s(i am confused wether 16 GB class 10 or any size class 10).
They again told me that you can only use class 10 on phone with processor clock more than 700MHz.
Is it right?

I presume they mean that you wouldn't get the full speed of a class 10 card.
A wildfire S at stock clocks seems to tap out at about 8MBps write, as opposed to the 10MBps a class 10 card is supposed to function at.
The SD card standard requires that a higher rated card must function in a lower-rated interface, just at the lower speed.

Simply our phone cant read and write class 10 at their full speed...so you can use it but for value for money you should go for class 6 16gb..i have it.

The CPU appears to be the bottleneck. It'll push class 10+ speeds if you overclock significantly. This guy clocked at 806MHz is pushing 11.2MBps writes.

If you are buying a new SD card only for being able to use data2sd, then may i suggest using app2sd first and then buy if you are not satisfied with the performance. And if it is for something else, then go for class 10. and overclock your phone!

Which 64gb sd?

Hi boys/girls,
I'm searching for a 64gb sd card but im not sure which one to take.. Id like a fast one xD
Any tips u can give to this noob??

I have the Sandisk which is fine for me. Still don't understand that my old Nokia N97 already had 32gb whereas the superduper quadcore hype devices of today are still stuck at 16gb internal memory. These should have been at 64gb stock. Ah well...

I have a sandisk one as well (class 10 sdxc). It's rated at about 30mbps vs the normal 10mbps. Works great so far.

Try to find ones that labeled UHS-1 (or UHS-I). If you want use torrents or others extremely high IO operations buy only ones with >40MB read/write specification (actual speed will be lower), otherwise stick with those with >20MB read/write.
ADATA has UHS-1 series 45MB Read/Write
SanDisk has UHS-1 "Mobile Ultra" 20MB Read/Write and UHS-1 "Extreme" 90MB Read/Write
List of course is incomplete, and all of UHS-1 labeled card also have Class10 label (because there is no higher Class)
Other that SanDisk "Mobile Ultra" will be expensive at 64GB and hard to find..

I've read somewhere Samsung micro SD 64gb is slightly faster than Sandisk one by a few mb/s transfer speed.

Ty for your answers peep.

I recently bought a 'SanDisk microSDXC Ultra Class 10 64 GB' and am very happy with it. I even managed to watch a 1080p movie with lossless DTS sound with it recently without even the slightest problem.

I also went with the Sandisk 64gb one, I formatted it in exfat with windows 7 and its been great for movies.

Great! Do u guys have an idea where i can get 1

Tell me your opinion about swap memory

I have a plan to buy a 16 GB class 10 sd card, and make a swap partition.
What do u think about that, because i have heard a few opinion about that. somebody said that swap is not good for our sd card, the other one said that class 10 sd card is good in writing speed but it doesn't good in random writing which it's mean class 4 is better, and many more
I just ask for your opinion, and probably u can give me an advice
Thx in advance :beer:

Go pull it off..
And then take a look at your sdcard, if there is a number inside a small circle, that's your sdcard class
Ussualy class 10 and 6 are written, but class 2 or 4 not
U could check it via sdtool too..
Class of sdcard means the minimum write speed of that card, if u found ur average writing speed 5 or 4, below 6 it must be class 4 sd card
That's what i know..

There is a huge thread somewhere here about SD cards and I got the idea that a classe 4/6 is better than a class 10 for this kind oh usage. I understood that a class 10 SD card is better for hd and recording videos but for random writing speed, lower classes are better.

Yeah, just like what i though..
And this is what i got from another thread :
" Class 2 and 4 cards have better random access speed and random read/write than class 6 or 10 cards in general. To get higher sequential write speeds, manufacturers sacrifice the random access speeds. That's just how it is.
The best all around card I've ever found is Sandisk class 4.
My 32gb Sandisk class 4 outperforms any other class 10 or 2 32gb card I've tested in the random access and random read/write speeds. That's what's most important when using with WP7 or Android when using it for apps or OS files that need to be accessed quickly. Class 6 and 10 cards are setup to initialize the area of the card that is about to be used to make the sequential write/read quicker, but it takes extra time in the beginning to do the initialization. If your using the card where you need to access small bits of info from various parts of card quickly, you will do best with class 2 or 4.
Most people seem to assume that the higher the class, the better the card is for everything, but that's not how it is. Different purposes need different kinds of speed... cards with higher sequential speeds have lower random speeds."

ty for informations guys
but what about im using it just for storage example: mp3
is there a differec for class 6 or 10 or 4 ?

This sounds cool.
Can anyone tell me how to get a good swap memory without memory expander?

Of course it's different each other..
As long as it doesn't need random access, i think class 10 is good, because it has hi-speed sequential writing speed

First, do u know why RAM called Random Access Memory ?
Because it access the memory randomly
In my opinion, An operating system need random access because the system files is located in different directory, and usually has a small size.
App need fast access to the needed file, and RAM do a random access to fulfil that purpose.
Get it ?
And sequential writing is something like you record a big size video, and it stored in the storage, i think that operation need fast writing speed only in one directory, so doesn't need a random access

SWAP partition is one of the best things introduced in Linux, and so on, on Android. It's so useful for our GIO, because of its low ram capacity.
I suggest to use it, but it will shorten sdcard life (in some cases). If you really need it, what are you waiting for?

Lucky me, received my new SD Sandisk 8GB class 10 and it's specific for mobile UHC-I so it has besides good sequential speed also good random access speed will replace old card later this week and give feedback on results.

I choose samsung because I wasn't sure of compatibility of other brand with my note 2 and it have got 10 years warranty. With other brand you will get only 2 to 5 years warranty. Also I got a good deal from infibeam.com magic box.

My girlfriend has the same issue, I will give her my samsung card and she can try if it is realy lies at the brand only.

Guys it is SANDISK and not SCANDISK.
Next always buy card of class 10. Most of the people do not know about it. Class 10 cards will only give you speed.
I am using Class 10 Sandisk 16GB and never faced issues.
Note Class 10 cards are costly rather than Class 4 cards which is easily available.

Sorry I didn't realise that the model I have is actually the one you have mentioned. I thought I had the extreme. I still don't feel that I get near 30mb so I would say that this is more than enough for this device imo.
