32gb class2 or 16gb class6+ SDCARD

I'm trying to decide if i should go for space, or speed.
For those of you that bought 32gb cards, are they class2? and if so do apps and such run off it fine, playing movies?
Class 6 is much more fast, and a class6 16gb card is still half the price as a class 2 32gb card.
Just looking for guidance here, do we need more then class2 for our phones.
Plan on putting movies and apps and stuff on the card.

I have a 16GB class 2 card in my Cappy, and I can play 720p video off it without a single stutter, and I never did install the lagfix, so class 2 SHOULD be fast enough, depending on what you want to do with it.
But right now, the cost of the 32GB cards is, I think, prohibitive. It costs > 3x what I can get a 16GB card for, and thus far, I have not filled my card yet.

I would go with a faster speed for the bigger size card, class 2 would be too slow if you are read/write onto it constantly; For the best bang of your buck, the Polaroid 16GB microSD (made in Japan by PNY) from Frys is going for under $20 (after rebate); Even though it is labeled as a Class 2 card, but under most SD benchmark app, it is detected as a Class 4 card (4.5 MB/s Write/15 MB/s Read under the 300MB file R/W test in SD Card Speed Test)

I would rather take a 2GB class 6 over a 32gb class 2. Class 2 is so unbelievably slow its unbearable. I use my phone as a usb drive very often. In my previous phone I had an 8gb class 2. It was so slow I thought the card was broken. So I RMAed it and the new one was the same. I realized that it just takes like 8min/gb to transfer to it. (and no its not faster in this phone)
Class 4 is standard, anything less is a waste of silicon and plastic.
Class 6 is about as fast as your average-quick USB thumb drive.
Yes class 2 is fast enough to run programs and play back video, but you'll spend a lifetime transferring those things.
Not worth it IMO. Get an 8gb class6 if cost is an issue. Also, don't go with any crappy random manufacturers. I find that a class 6 from 'craptasticMEM' is nowhere near the speeds it should be, and in fact usually slower than a clas 4 I have from kingston.

The class rating has nothing to do with playback speed, only write speed. Copying files is faster, but how often are you loading up your SD card from your computer?
I am using class 2 and it is recording video just fine. I am not sure why above poster claims "class 4 is standard" - that would imply that class 2 is sub-standard. It is not, it just has slower write speed.
Keep in mind that if you lay out the big bucks for a class 6 32GB card today, it will half the price in a few months.
Now in my HD Camcorder it requires Class 6 to record 1080P - our phones have no such requirement, so anything above class 2 will help in initial data transfer from PC - after that you may never, ever see any benefit.

Yes, sorry you're correct. Class 4 is standard in my gauge of memory cards/usb drives. All the classes "should" perform fine. The higher classes are obviously faster (with significant brand to brand variation). I find that they are faster at everything though. Not just write, but read as well. A class 6 card is as smooth as the internal memory in the captivate. A class 2 card is abysmal at everything (in my experience). I say class 4 is standard because class 2 is really bad...

It could be my blindness - not physically, but the ignorance of not having a class 4 or 6 to compare to my class 2. My class 2 works fine for me, but if the class 6 stuff gets cheap I will head on over to it.

its not healthy to lie

you guys are missing the fact that the class ratings are a MINIMUM rating. a lot of brands will perform MUCH faster than what they have printed on them. just saying something is class X is pretty much pointless. it's just a guideline that is being loosely followed. benchmark and move on

If your running apps off of your card than believe me there is noticable difference between a class 2 and a class 6, and yes dont go for a no name.

I don't believe you. It 100% fully depends on the card. Some class 2's are faster than class 6's. Ratings are lies.... benchmark ftw!

True that. Ive found significant differences by brand. However, there is definitely a noticeable difference between a class 2 and a class 6 card.
What you get depends on personal requirements more than anything else. Faster or more storage?

[Q] Why class 6 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

[Q] 16GB class 2 vs. 32 GB class 4

I currently have 16 GB class 2, and i am about to but 32GB class 4.
what is the diffrences beetween them ?
The games will work smother with class 4?

I have a 32 GB class 10 micro sd card, bit I didn't really notice any difference in speed compared to the 8 GB class 2 micro sd that came with the phone...
Sent from my R800i using XDA

The class rating of an Sd card is based of off its Write speed. So a 16gb class 2 would write at 2mb per second, the 32 gb class 4 will be able to write at 4mb per second, There is a slight "catch" however when using larger storage Sd cards, its been explained to me in the past that when you go up in storage it takes the device (phone, pc, camera ect.) longer periods of time to initially read the card itself because its now reading through more storage space then before (even if that space is empty in places).
With that in mind, the 32gb class 4 will Write files to it self at a faster speed then the 16gb class 2, but it will take your phone longer periods of time to access the information on the larger Gb card, so will games play smoother off your Sd card, technically no, they wont. But what you will achieve are faster data transfer rates when moving files to and from.
Also take into account that the class rating system isnt exactly perfect. For instance my 32gb class 4 is rated to write at 4mb per second, but its achieved 6mb per second depending on the files, and Im currently using a 32gb class 10 which most of the time writes data at 12mb per second.
I hope this helps

I think the best would be those samsung or sandisk ultra class6 cards.

There was some other thread around where people found that class10 cards had higher latency and slower access times than the class4 ones. So they're not really suited for mobile phones where quick data access is more important than high transfer rates.

I still believe storage size has a greater effect on access time then the class rating, classes are read/write speeds but more space takes longer time to read. The class itself being suitable, depends more upon the manufacturer of the sd card, and the manufacturer of the device and the device its being used in. A 4gb class10 is going to give you great performance in your device where as a 32gb class10 will indeed function a little slower but depends if you need all that space or not. I'm no expert but that has been my experience.

It will decrease its "lifespan" but probably won't kill it, I think the apps2sd script bumps things up drastically and I didn't have any troubles for the while I was using it, but the SD card manufacturer and its class might have some effects on the bumped up lifespan .. probably good to at least make sure you have a spare!

I indeed have a spare one that I am using in my OG droid. Lol. I use that phone as an ipod touch like device. Too bad I don't have a sim card because I'm on cdma. If I were, then I could use my OG droid when I want to use a slimmer phone that has a physical keyboard. However, SwiftKey has me not missing my physical keyboard.

What Class SD Card is best for SPEED/SMOOTHNESS for DATA 2 SD CARD SETUP ROMS

Also, whats an easy way to find out what Class your SD card is?

It is written in on the card itself.
Why two threads? This is not a news group.
Sent from my HTC Desire using Tapatalk 2

The higher the class, the faster the card, max = class 10.

Class 6 card should be fine for speed and will cost less than a class 10 card which is only needed for speed freaks.

Just look on your card! On my Sandisk 16GB microSD there is an open circle with a number (4), this number is the speed-class!
Recommended for the Desire is Class 4 or 6, Class 10 seems to be incompatible with Desires Hardware and produces lags!

I use a 16 GB Trancend class 6 and it works perfectly. My 6 GB class 6 card was way faster though.
By the way, the method of A2SD used is also very important. SenseEvolution was a lot slower on my HTC desire than Mildwild and both use A2SD, though in a different manner.

I'd recommend a Transcend Class 6 for Data2SD

Im currently using Marange's MIUI V4 rom latest version 2.5.18

the rom is really fast and pretty darn stable but every time i open an app that downloads alot of data or is larger i have to wait from 5-15seconds for the menus to pop up, its basically just waiting at black or white screen, i believe this to be because of my sd card but im not sure... alot of apps are normal but some like facebook is the worst and whats app takes about 5-8seconds to open up fully aswel...
is there anything i can do ? i have a 16gb sd card

I have testet with benchmark and found, that the class 10 card has no more speed as the class 4 card. So what, i use the low budget but high capacity class 4 card 32 gb.

Thanks for your observations which are probably useful to someone interested in those kind of roms, but when you say something is...

Because sdcard and it's class is only one part of the coin. You have random i/o and phones memory controller. Any of the links in chain not working as expected (to be taken relatively as Desire was not intended to use >class6) and you'll get crappy speeds.

Even class2 runs fine for me and it is faster than the specification since it does anywhere betweeen 3-5mg/sec instead of only two.

[Q] fastest 64gb card for note 2

hi everyone.
im looking to get the new note 2 and would like some suggestions for a the sd card preferbly 64gb one.
i have looked on some sites like memoryc for ideas but would like suggestions..
the prices ive seen listed are all within my budget so need a compatible fastest if possible 64gb card and which brands are the best? is sandisk still a good choice as i have seen samsung bringing out a new range and they are usually cutting edge last time i remembered.
for example is the new format compatable microSDXC??
"64GB Sandisk microSDXC CL6 Mobile Ultra memory card"
thankyou.

fastest card is sandisk extreme pro, but ur phone wont be able to use those speeds, plus its expensive. My suggestion is the sandisk mobile ultra, best bang for the buck.

I'm sure it's a similiar issue as it is with cameras.
Someone needs to do a sd card speed test to see what the read/write speed limit of the note 2's hardware is.
It's probably way under the speed of that SD card.
However, getting a faster card means you can transfer stuff on/off of the card a lot faster through your PC.
This is useful for copying movies on (or for cameras, copying off tons of pictures).

ill be using it for HD 720p movies + HD Video rec and photos too thats why i wanted speed for writing and copy from pc and for good rec/playback.
so ill stick to this then 64GB Sandisk microSDXC CL6 Mobile Ultra its a good price and should be good for what i need at 30MB/sec
thanks again

No!!!! CL = class, and higher should mean better.
CLX means the card is guaranted to read/write at X meg/second.
However, people have found that higher quality memory cards exceed their class numbers,so YMMV.

fixed.
Class 2 means minimum write speed of 2MB/s.
Class 10 means minimum write speed of 10MB/s
read speed can still be varied. It's also possible also to get class 6 card that write at 8MB/s, it just happen to guarantee at 6MB/s. Also I have seen like Class 10 SDXC(not micro) that can read at 40+ MB/s. I would read review at amazon and newegg to get the general idea b4 buying on.
