Increase performance?
I've a 32GB class 10 sd card, very curious to know if having another place for apps to load from would increase or decrease performance?
Thank you

Although I tend to try to store my data mostly on my sdcard the internal memory def is faster at reading and writing ..

Hi guys, jus wanna knw if there is any difference in the performance of the phone (other than jus transferring files to n from pc) according to the class of the sd card?
Thanx

Yes there is. The class tells you the transfer speed for witch the card is rated.
For example, my card is class 10. That means that its capable of transfer speeds of up to 10mb/s. Same for others.

So that transfer speed of 10 mbps refers to the speed @ which files are being transferred to n from pc right?
My question is apart from that will it affect the performance of phone when i hv apps in ext (a2sd)

Yes, speed class is guaranteed write-to-card speed in megabytes/second (read speed is usually even higher). Obviously, the bigger class, the better, but high-class also much pricier. And you unlikely too see much speed difference if you just want to put some apps on SD card (well, depends on the app - some games are 300Mb+, and you'd see the difference).
But if you for example want to watch movies on your phone, you may find that slow speed class, like 2, is a pita to wait for while a movie transfers from your pc ;-). Class 10 would be a real hit then (especially if you write files using a cardreader, it may be not as good via USB to a phone).
Hv a class 2 1gb card, planning to get class 6 8gb card. So i should see significant performance improvements while havin ext partition right?

Don't know how much will it cost.
Priority is card speed. Higher class is faster: http://en.wikipedia.org/wiki/Secure_Digital#Speed_Class_Rating
dont know the cost...my advice go for sandisk HC mem card class6 or a class 10...ur phone performance vl increase gradually ..
iam using a class 6 16gb my xpm is pretty faster than before.

Phone performance isn't affected by SDcard.
The only difference you can see is when you read/write files from SD, nothing more.
Web browsing doesn't get faster with higher class SDcard. Calling doesn't get better with higher class SDcard.
And Class 4 is enough for Android, I've never had problems with it and the speed is enough for me.

If you want to copy about 4 GB of data to SD from PC with class4 card and then copy same file/s to class10 card the time is a lot shorter with class10!
This is why many people use higher card class.
And when you want to have system in externel memory* this require minimum class6 card to avoid lags.
* e.g. HTC HD2
my Sdcard is 16GB class 10 (sillicon power) and write speed is 8 - 9 MB/s and read speed is 16 - 17 MB/s , this is very nice SDcard

I agree with u...but music player and video playback performance increases...and also after a reboot when u have apps installed in the sd it loads faster in the app drawer.

I think you should use SD 8GB :laugh:
Hi guys
I'm looking to buy a Micro sd card, samsung 32GB, class 10
So my questions are:
1- If someone already using sd card just like this one, tell me is it working fine with your android device?
2- Do you think that patriot or some other manufacturer cards are better then samsung?
3- Does your phone in some cases really feals faster with an sd card with bigger class number ( does reading speed of your card effect phone's speed? )
4- I heard that class 6 ( 6 MBps ) is more than enough for android devices, and also that some class 10 cards slow down a device, is it true?
5- Will i ever have enough memory on my phone
I know that there are the same threads on forum somewhere, but i need answers quickly and thats why im opening this one..

1. It works fine.
2. It just user preference. Their both great.
3. Reading and writing to the SD card will be faster. It won't affect phone speed unless your device is using certain mods such as swaps, int.ext. sd swaps, etc. or you have apps on your SD card.
4. While class 6 may be quite fast for a device, there is no way a class 10 could be slower.
5. That's up to you .
tnx Theonew
if i understood it well, an app called swapper 2 can allow device to use some memory from partitioned sd card like a ram memory and provide it a slightly better multitasking, and speed.. ?
And i have read that it can also affect an sd card's life..
So, is it worth it?

Yes, swapping can degrade the life of the SD card but it is worth it if your device is a low-end one (and slow). It will assist in stuff like gaming, etc.
No, I really don't think its worth it. It really affects the cards life and does not really add much ram, even for slow phones...

An additional 256mb is quite a lot compared to 192mb (total).
Quick benchmark of Samsung SD card class 10 in the ASUS Transformer TF101.
Code:
[email protected]:/home/kuisma# hdparm -t /dev/block/mmcblk1p2
/dev/block/mmcblk1p2:
Timing buffered disk reads: 60 MB in 3.09 seconds = 19.43 MB/sec
Reference, the internal nand flash (/data partition):
Code:
[email protected]:/home/kuisma# hdparm -t /dev/block/mmcblk0p7
/dev/block/mmcblk0p7:
Timing buffered disk reads: 52 MB in 3.10 seconds = 16.79 MB/sec
If comparing read vs write, large blocks vs small, sequential vs random etc, the SD Cards wins a few times, the internal flash a few. It's more or less a draw. I would say this SD card got "good enough" performance, although far from SSD performance.
good enough for smartphone
are you talking about solid state disk?

hello everyone, im new and i have a question: i want to buy a memory card for my GT-I9300, but i dont which memory card i should buy, because i play a lot of games on my phone, like need for speed so i need a really fast memory card. so what will be the speed i need fo a memory card?
Sent from my GT-I9300 using xda premium
For speed, I recommend you keep games and apps on internal memory, and you can put all the songs videos, pictures on an sd card.
But is 95 mb/ps reading speed enough for large games?
(thanx for the answer by the way )

Look at the top of this thread for SD card info. It's sticky'd
keep games and apps on internal memory...that give you speed to launch them
I'm using a 32 GB Class 10 SanDisk's microSD, and I knew that SD accelerator apps improve SD/Phone performance, but also I read about risks about use that apps. Is it true that are risk on SD card?
The only thing I can imagine is that they increase write access so that it dies faster.

if your experiencing slow sd card write/read speeds then you can try but i have read in other forums it decreases the life of memory card i use a class 6 8gb and my experience is just great :victory:

why would you need a sd-booster for a class10 mem. card?? there is no need, I got class 6 & performance is more than fine & if you use some booster, its goona decrease card's life..
