Hi all,
Recently, i have changed to Sandisk Mobile Ultra 16gb Class 4. Did a speed test on it with atto benchmark and it is able to read/write with an maximum of 19mb/14mb per second.
However, when app2sd+ is applied, I found that in certain apps or games, there is still an lag with the applications. (This is most obvious in games). If app2sd+ was not apply, such lags are seldom seen.
Thus, I feel that having app2sd+ is a great incentive for large storage but at the price of speed.
Are there any available tweaks out there that is able to improve the speed of app2sd+?
Pardon my poor english.
Thanks.

Yes, I suppose. I use a Kingston Class 10 microSDHC and I've never had such problems. I can move whatever I want to that card and cannot find any difference. Also, navigating across 300 images is very smooth.
But sadly, Class 10 cards are still very expensive, especially if you want 32 GB.
Would a Class 6 be good enough you think?
There must be something wrong somewhere.
I've had a Class 2 16gb Sandisk card since back when I had a G1.
I've used APPS2SD+ all the time on the G1 and used it for a while on the Desire until I moved on to Cyanogenmod.
All my apps run as tho they were installed on the phone, regardless of what people used to say about different classes.
I have some big games installed like Fifa 10 and Zenonia and get no lag at all.

i played caligo chaser on my desire.
this game has some obvious lag when i am using app2sd+. but show no lag when i install them on phone.
not sure is it because, it is writing to both fat32 partition of the SD card and ext 3 partition on the same SD card at the same time when it is running thus causing the lag.
Does anyone know at what speed is the phone capable of read/write to the SD card?

Hi all,
I've read in a few places that if you want to run apps from your SD card that you should have a class 6 SD card. Can anyone explain why this is? I've currently got the one that came with the phone, which is class 2. Just want to understand why I need it before splashing out the cash
Thanks
It's all about speed. Class 6 is faster than Class 4 is faster than Class 2. If you are happy with the performance with your Class 2 card, no need to splash out the cash.
yeah its just about speed, the higher the class the faster the r/w speed, you dont really need a class 6 these days tho, maybe in the old days of the g1/hero but not now
There's quite a bit of discussion on this and I'm honestly quite confused over this as well.
The higher classes just means faster write speeds but same read speeds. Certainly, this shouldn't affect the performance of apps that are installed on the card; unless the card is being used for swap memory.
Anyway, I've heard some users with 32GB microSD card (only available in class 2) using app2sd with no ill-effects. I've recently purchased one myself and will be swapping it out later tonight.
newbie on Android here.....may I ask....Im currently using a 16Gb mem card....If I change it to a 32Gb, what are the files that I need to copy to the new card, so that the apps/games currently installed will still run? I noticed there are so many folders inside my memory card now.....which one should I transfer to my new card? Or should I need to re-install the apps?
thanks..

are you using apps2sd? or just running a stock like rom?
9 out of 10 users on this website would not be able to tell the difference in speed by running apps on a class 4 or class 6 cards.

Before the usual flamers get to write on this topic to say high-class cards are useless, it really comes down I think to the time you have available to wait for USB transfers. On a class 2 it takes AGES. I bought a class10 16gb and it's an absolute life changer (i do have a lot of public transport so I make heavy use of my phone as a video player)

Another reason to have a class 4 or faster card in the phone is to have reliable 720p 25fps video recording. On my Class 2 with a2sd+ recording stutters.
thanks for the responses. from what i read previously, it talked about class 6 cards being less likely to be unmounted and causing problems to running applications. does this mean anything to anyone?!

This is the reason when I eventually get the money I'll be getting a 16GB class 4 or 6 card. At the moment 720p is fairly pointless to me since I can't get smooth recordings with my SD card.
Have no issues with my 16Gb Class-2 sdcard. R/W speed enough to handle 720p recording and rockplayer playing avis perfectly.

Are you running A2SD or a2sd+ on your phone? If not, that may be the reason.
The more apps and widgets and stuff is moved to the sd, the more r/w-access happens to the card, which has serious impact on video recording. I really wish the internal memory of the Desire wasn't so small. What the heck did HTC think by putting only 560 MByte internal storage into their android flagship? The SGS has 5 GiBytes!

Incorrect!
The class of the card doesn't tell you the speed of a card - it tells you the *minimum* sustained write speed on a card which is completely unfragmented
A good quality class 2 card can and often will be faster than a poor quality class 6 card.
The two Sandisk Class 2 card I use both write at around 7.5mb/s, which is faster than the class 6 minimums.

Dave

That's interesting info! Would explain why I have far fewer problems than most people report with 720p recording onto my class2 card.
So the real answer is: Benchmark your write speed before making any big purchasing decisions on SD cards.

so a class 4 good enough for 720p? i have a class 2 right now and the recording is just horrible.. i thought that my phone was broken and have changed many custom roms
Bought a C6 16gb to replace C2 4Gb - definitely faster as USB drive - both Sandisk
I hope you all now the game becouse its epic. My problem is that it is not as smooth as it should be. In build phase it is perfect, high framrate, no lag....
But in combat phase when more than 10 enemys are on the screen than its getting laggy. It is playable but i just dont like it. How to solve it?
I have a 16GB Class 2 SD card. Would a qicker one solve this problem?
The overall performance of my favorite class 4 sd card has been smoother then the class 2 but I'm not sure it will help the lag. How lggy is it? Is it unbearable because when I played it, it only lagged slightly..

I found this for a while too, I found the reason was the battery was overheating and even caused the game and sometimes my phone to crash! I solved it by getting a new (bigger) battery and by rooting and removing bloat - contacted the devs but they won't update the game till its fully released!
Guys, what's the file size of data file? I only have 700mb left on my sd card, and I'm planning to spare atleast 300mb on it..
Are there many players always online?
I've always had some slowdown while playing. They released one update that improved the slowdown a little bit, but it's still noticeable during game play.
I am having an 8GB class 10 Toshiba MicroSDHC with technical reading speed indicated at up to 25mb/s and writing speed up to 20mb/s but I usually can only get slightly more than half of its full speed capability when running a benchmark Is it because I did not perform an initial format for the card or the Play does not support such hi-speed transaction?
It has been proven that the Xperia PLAY and probably other phones as well have problems with Class 10 cards. The problem with Class 10 cards is that, while they have super high speed writing capabilities, there goes a trouble with reading speeds. It has been proven in games in which during gameplay, the games that were tested lagged to the point of unplayability while they are trying to read game data (or SD files, more commonly) from the card.
Users here mostly recommend Class 2 and 4 regardless of the capacity.
PS: I can live with Class 2 microSDHC, so why can't you?
Well, I was attracted by producer's advertisement of their so-called fastest microsdhc in the market and did not know the fact that my PLAY does not handle such speed.
Since I already bought it, do you know if there is any solution now to overcome this problem and utilize the full capability of the card' speed?
honestly, i don't know. first things first when buying new hardware, read and read and read and read and read and read a lot of reviews until you are satisfied. never read company claims because they are just marketing strategies, ALL LIES, rather, read user opinions.
since you bought it already, all i can think of for it to not be wasted is to just buy a card reader for it and use it as a flash memory stick for your laptop or desktop instead. i mean use it like a regular USB flash drive. that's just my opinion though. you really can't stick a Class 10 card on the XPlay. all hell will break loose.
start looking for class 2 or 4 instead.
So sad...I thought I could somehow improve my PLAY performance. Anyway, I think I will use it for my Digital Camera instead and start looking for the class 4 one as your advise.

Class 10 cards are KILLER in a digital Camera. I use one in my Canon Rebel T1i and continuous shooting works so much better and faster with a Class 10 card. Also much smoother video recording if you record in HD.
BTW the best card for this device is the Sandisk 32GB Class 4 card. Buy from a reputable seller as fakes are out there...
I am currently using a Sandisc 32gb Class 4 card and there are slight lags on Modern COmbat 2, my old card was a class 6 16gb card. I saw better performance on the class 6. I am aware of the class 10 issues. My question is I am currently using SD card speed increase software to cahgne the Android cache size from 128kb to 4mb, is this software make a difference? Just curious to get peoples input.

i'd stick to class 2 if i were you, it's slow when writing (but that's already fast for me), but it's fast when reading.. at least no lags when something operates within the card..
and oh, is it true that SanDisk get their cards from random unbranded producers then label them with "SanDisk"? If so, then I won't trust this brand anymore..
what is the best brand then? they say it's only between SanDisk, Kingston, and Transcend. But my sister had problems with Kingston USB Flash drives where they periodically corrupt files and have slow writing/reading speeds and that gives me a negative feedback on the whole company. as for Transcend, i think it's too cheap that the quality might be substandard.
I'm still using the stock card that came with my Play (i don't know but it doesn't have a brand) and it's doing its job pretty well. i'm considering an upgrade soon.

It is a great information indeed. I am more confident for my next choice of card now.
Problem with high class SDHC cards is that they're good at big files, but suck at small files like game data files on phones.
Class 4&6 are the most versatile for all the various things you might do with the phone.
Also, I've always found SanDisk to be the most reliable.

Hi guys, I'm planning on buying my Xperia Play a new MicroSD but im not sure which is better. I've read that 32GB Class 4 are the best one's for gaming but I'm currently stuck between Sony 32GB Class 4 MicroSDHC and Sandisk 32GB Class 4 MicroSDHC. I want to get Sony because, of course it's the same brand as our Xperia Play and i thought that it would be much better. But seeing the posts here, people are pretty much inclined on getting Sandisk. So I wanted to ask this myself, which would you prefer In terms of Quality and Price? Thanks!
Get a class 4 or class 6 sandisk and your good to go for gaming.
Yea I'm with cherry2k but the higher the class the faster the card

This is a huge debate among many people;
"Higher class?" vs "More Space?" vs "Manufacturer?"
The truth is :
The more space you have the longer it takes to read, the higher the class the faster it can read all of the space
The Class Rating is "The highest speed the manufacturer was able to obtain, that was stable"
With the theory in mind, getting a 4gb Class 10 will of course be much faster then a 32gb class 10, will you notice it while gaming? I never have honestly. I am using a Samsung 32gb Class 10, averages 10-13mbs write and 15-20mbs read, I encounter no slow downs during gaming, and have compared this to my Sandisk 8gb Class 10 against gaming (Modern Combat 4 was tested in both cases on both cards, with the App moved to Sd card as well) I move everything to SD that I can.
The 32gb Class 10 should be perfect for everyone, for your photos, videos, and yes even for your gaming! I will debate and back this up all day.
