Going on a long long trip and only have room for my Dinc.... Will a class 4 card get the job done or do I need to get a class 6?
Thanx!
That really just matters when copying/writing the initial file and on read times.
For video saving or video playback, it might save you and extra few seconds during the save or load times, but it shouldn't matter at all.
I have a 16GB class 2 card, ran the SD card speed test app, and it came out as a class 4 card.
I notice perfectly fine speeds on my card. I never seem to think to myself, "this thing is damn slow." If you do something like sync 500+ songs to the card at one time, sure it may take a little while to initially find them, but after that there's no wait.
Hope that helps.

I just made a post about class and brand in the accessories section. Take a quick look at that. But class shouldn't really save much time unless you are recording really long videos, the most it will save you is maybe 2 seconds TOPS after finishing video recording. My sandisk 16GB class 2 saved videos in 2.5 seconds or less.
ok, thanks for that info. i was under the impression that the write speed of the card was a limiting factor in bitrate/framerate. Therefore I would get better video quality using a faster SD card. I have seen posts where peeps complain about jerky video @ 720p and the class 2 card is most always the culprit.

Well considering it isn't attempting to write the video as it is recording, class does not apply to this. Framerate/bitrate is controlled by the recording software and the camera itself. SD card just stores the finished product.
More for less, or same for more?
Rather than pony up the extra benjamins for a higher class card, why not get the/a bigger 32 Gb class 2 card, like the one from Verizon?
I have it, it too tests @ class 4, I've had no issues whatsoever.

Well it depends if someone needs faster transfer rates or higher capacity, as well as cost difference. 32gb cards are going for 75 to 90 bucks still being that they are still relatively new, while a 16gb class 10 from kingston is about the same price, maybe even cheaper with transfer rates at least 3 times faster than any class 2. All in preference.
So as far as media playback goes, will I notice much of a difference on class 4 vs class 6 on a 32 GB card? The speed difference is really in file location, not playback right?
Basically, yes.

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..

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
Thinking about upgrading to a 16gb sd card. I noticed that a class 2 goes for like 19 bucks while anything with a higher class is 30 bucks or more. Will I really see a perfromance boost if I get a class 4 or 10? If so, what will increase? Will photos load faster? Will the videos I record in 720p have a faster playback? Etc. What takes advantage of the class speeds?
Thanks for any input guys!

If anything, for video playback the faster class sd's will/should eliminate stuttering issues etc.
Here's a good breakdown of the diffs: http://www.sdcard.org/developers/tech/speed_class/
I would say given the lack of a2ext on this phone there really isn't a need for anything higher than a class 2 on this phone. The only things it would help with are:
1. If you use linux swap (stores the cache on the sdcard)
2. If you've moved your dalvik to the sdcard
3. If you use enomthers rom which has a2ext/linux swap
4. Video playback/recording (maybe)
5. File transfers. Large files and sdcard backups will be quicker
That's really all and if you don't use most of that stuff then I'd just stick with a class 2 and suffer the slower transfer rates. You should be fine with video, I've used a class 2 and 6 - video was the same as far as I could tell but certain videos (movies) might shutter a bit with the class 2, I never tested that aspect.
Sent from my T-Mobile G2 using XDA App
Also note, the class is simply indicative of the minimum write speed, not read speed. Things like playback and load times are not affected that much (though things like 720p video recording could theoretically perform better).
Also, because the class is the minimum speed, a lot of the time the higher quality class 2 cards may still achieve class 4 of class 6 write speeds.
Ahh, I see. Thanks for the info guys!
Does anyone know the common write speed of the stock 8gb card?
Sent from my T-Mobile G2 using XDA App
I believe the stock card is class 4 so the minimum it should be able to write is 4 mb/s. Not every card is created equal. If you search on google you can find apps that help you test the read/write speed of the card.
I'm pretty sure my stock card was a class 2. I now have a 16gb class 2 card, and it seems to do everything fine... including video recording.
The stock card in my G2 was a Class 2, though for my wife's MyTouch 4G (bought on the same day) she got a Class 4.
When I had my G1 I switched from a Class 2 to a Class 6, my picture taking got noticeably faster, I used that same Class 6 in my G2 so I can't really compare it to anything there.
My stock card was a SanDisk, and they only make Class 2 cards. I use my Class 6 card in the hopes that more the Android modders sees the sense in having a /system/sd folder leading to an ext partition.

There's pros and cons to getting Class 10 cards.
From what I read, Class 10 offers the best read/write speeds so this is a positive point.
The problem is, the random access performance of higher class cards is not as good as the lower class cards.
Some users have stated that Class 10 cards in their Android devices have created lag, which is attributable to the lower random access performance.
Personally, I'm using a Class 4 32GB Transcend card and so far I've not experienced any problems. I did use a Class 10 16GB Kingston and it my Play did suffer some lag.
I think the main advantage of higher class cards is performing file transfers between sources, as the higher write/read speeds would indicate.
yes that is true some people say that there class 10 cards give them lag in games.
i have a class 10 memento card in mine but i havnt had any lag issues
but i do notice that transfering large amounts of data
and loading games times are faster on a class 10

If you look on the microSDHC card, it will have a circle with a number in it. That is its class.
If there is no number, it is Class 2.
I bought a class 10 Lexar 32gb microsdhc and i was shocked when i put it in my play. It was lagging in all the gameloft games most noticeably in Sacred Odyssey. I returned that and bought a 23gb Kingston class 4 and i have no problems with that .
I think its because the card had problems reading lots of small files, i noticed that when i was copying my data over the speed was coming down to 1mb!

I am personally using a Samsung 32Gb class 2 card. It works very well, no noticeable lag in any of my games, be they Gameloft or Fpse. I have a Sandisk 32GB class 4 card I plan to move to, just to lazy to copy everything over right now.
Im using a class 4 sandisk i got from amazon uk for £49.99 no problems here. One thing i can warn you about though is dont go for a class 2 card because if the xperia play ever gets 720p video recording a class 2 card is not going to cope and you will have a loss in recorded frames.

It's not that bad, and digital zoom (which is the only zoom phone cameras get..'cept for that one japanese one..) is just as effective as zooming into your picture after you've taken it. It's a useless, garbage feature, and everyone who misses it should be ashamed.

well digital zoom is pretty ****ty anyway, it is pretty much zooming into the full size image live and then cropping it and enlarging it. You get better results taking a full frame image and then zooming and cropping on your pc.
I also have read in other places that the play is capable to 720p.
Sony usually likes to keep thing hidden so when they release an update you stop raging for a while because there are pretty new things that the device has always been capable of.
I use my 32gb I got from my Thunderbolt. Which is a class 4 and I have to say it works like a charm and way better than its 8gb class 2.

I don't think I would ever see a difference in the speeds available in "classes" on my phone unless it was a defective card. I picked up this card on amazon and have been very happy.
Sure, I'd love a class 10 card but I don't think the DInc2 can even do anything with that. Nor can my bank account take it
I'm a little surprised the prices haven't come down further.
The only way you will benefit from a class 10 card is if you do photography in raw format with a requirement for rapid snapshots or 1080p video recording in a higher quality. You'd be better off saving the money by getting a good quality class 6, or even a class 4.
I'm using a Kingston Class 4 32gb card without many issues. I did have a weird issue with the 720p recording at one time, but I haven't tested with CM yet to see if it was possibly a software glitch.
Your phone will perform poorly with a class 10. Higher classes have faster sequential access times at the expense of random access lag, and the vast majority of what your phone will be doing is random access.
The only things that benefit from class 10 is things like cameras, that write huge files (sequentially) all day.
The short answer is get a class 4 or 6, Sandisk tends to have good random access stats.
Just for reference, the DINC2 comes with a a SanDisk class 4.
Hey everyone, I've never purchased one of these for a phone as they've always came with one. Anyway I'm looking for a solid recommendation for a fast 32GB SD card. I have a Tiger Direct local to me so I'll probably try to go their today once I have something to reference.

I use a class 4 32gb sandisk and the speed is fine. Lower class cards are more realiable and the average user cant tell the difference unless you're transferring large files or large quantities of files at once. My class 4 acts like a class 6 but is super reliable.
Id highly recommend a class 4 over a class 10. There's a thread around here if you search that will tell you the benefits of a class 4 and lower class against higher class cards.

isn't the only thing the class does is gauge the speed of transferring files to and from the sd card, not the actual performance?

Higher class, like another poster said, will give you higher speeds for large file transfers. However, this comes (from testing) at a sacrifice in everyday use of read speeds on everyday smaller files (think gallery, music player, etc). That's basically a short summary of what other XDA members have found from testing. Personally, I picked up a 32GB card from SanDisk off of Amazon and am completely satisfied. You may have a slightly slower time adding all of your files initially, but you most likely won't notice the difference when accessing all those files later on the phone. Look up the card on Amazon and the corresponding reviews and decide for yourself. Hope this helps.

personally, i find those Class 10 to perform better for me.
the time it takes to write/read small files is negligent compared to the amount of time it takes to write/read large files like MP3, MKV, etc
those word documents/excel spreadsheets, pdf, notepad texts, loads up instantly on my Adata 32GB Class 10. and i got 3 of them
1 for music
1 for videos
1 for apps/games/docs/work
so again, that is yet another one of those where the benchmark says one thing, but real life usage shows otherwise
