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:

Some Swap scripts arent good because they decrease sdcard life but i have app named Ram Expander (Swap) which i bought from play store and its great! U can set swap file upto 2GB and increase ram! I have 602MB swap! And my memory total is 880MB

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."
Now i understand why my camera using class 10 sdcard

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.

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.

Samsung, sandisk, pny, lexar and patriot all have class 8 and 10 floating around the interwebs but the evo doesnt need anything higher than a 6 unless u want to transfer alot of data between your phone and pc since the ohone wont read or right faster than class 6 speeds

They make class 2-10 but the evo just doesnt have the hardware capability of going past true class 6 speeds however most of the new phones can handle class 10 so when u upgrade u wont need a new card if you want your class 10 to perform better in the evo u can force it software wise by using a 2mb /2048kb cache size on the sd card sd speed increase on the market by daniel meriman works good for this and can be set at boot there is a chance of damaging the card or slot by doing this but i havent had any issue yet and ive been tweaking my sd speed for a long time now

They again told me that you can only use class 10 on phone with processor clock more than 700MHz.

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!

If your not switching your sdcard with your internal one then I doubt you will notice a difference between the 6 and 10 since all apps are stored on the phone.

There is an extremely noticeable difference if you are copying files from your computer. I am always copying a lot of video to and from my card and a 66% increase in write speed saves me a lot of time.

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.

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.
