I have a Magic 32A, i purchased a Class2 8GB a while back, is it necessary to change it to class 6?
No, the class 2 card should be working fine, it's just gonna be slower.

Try the general category/section next time you have a non games/application related question!
Actually the class rating is for write speeds more than read. If your just using it to store music, video etc and not apps2sd or swap (why would you with a 32A?) than there should be very little difference.

their speed is directly related to the class.
class 6 goes 6 times faster than a class 1 and so on.
whatever you read/write on the SD will suffer from a class2.
FYI, gallery etc they all create thumbnails etc on the SD card (no matter is your using app2sd or not).
I would DEFINITELY not get a class 2.
Maybe a class4, but with the difference in price I dont understand why not a class6.
I found very little difference between class 2, class 4 and class 6 when using for storage. (music, photo etc) These where all of the same size for testing (4GB cheap) and there was no noticeable difference in any of them as far as opening music form the player or browsing the gallery.
I know here in Canada if you can find them class6 16gb cards are twicw as much as the class2 cards. I paid $52 for my 16gb class2 and the cheapest I can locate on in Canada is $111 plus shipping, so not that cheap.

A thing to remember, is that the class is the minimum guaranteed speed – not the maximum. So a class 2 guarantee you a speed of mimimum 2MB/s, a class 4 - 4MB/s etc. But the maximum speed is actually the interesting thing – and that depends wary much on the quality of the card.
So when you buy a new card – have the quality in mind. I’ll rather buy a quality brand class 2 or 4 card then a “no-name ebay” class 6, as the maximum speed of the quality cards is properly better than that of the no name one… ;-)
I have gone through a dozen or more cards and I can tell you class 6 versus a class 2/4 makes a difference. The size of the SD card also makes a difference, the less space to look in the shorter it takes. If you bought a $300 phone like me $35 isnt so bad to make the most of it. My perfect balance is the 16GB class 6 I use in my daily phone, plenty of space and fast for apps2sd.
stock class 2(?) 1GB upgraded to 8GB class 6 on cyan 4.0.4.
I noticed it has sped up a LOT, mostly noticeable when typing, I have turned on vibrate and its still faster.

Evening XDA!
So... It's time I upgraded my HD2's capacity. 16GB MicroSD's are now reasonably (ish! @ under £30) priced so that's what I want to go for. Most are Class 2 but I've seen a few Class 6s knocking about too.
Is the speed difference, in reality, a massive issue? Stuff I do that perhaps might require speed:
Watching XviDs in TCPMP
Taking photos
TomTom/iGO
Music
Will I notice much of a difference between the two classes of cards?
Any feedback is much appreciated! Thanks!
u just can compare my
kingston sdhc 8gb class 6
to
sandisk sdhc 16gb class 2
i could figure out a speed advantage of the class 6 about 0.8 mb per sec
my 16gb class 2 got 3.8Mb/sec
my 8 gb class 6 got 4.5Mb/sec
copiing the same file....
if somebody got different rates pls post them there.
i never had any problem with the lower data transfer rate of my 16gb sdhc, smooth vids, instant starting apps, nearly same "short" install time for apps
Ps.: i was copiing a 7xx Mb video file to my HD2 in HDD mode
I have a class 2 16gb in my HD2 - I've had no problems with the speed.
watching AVI files with coreplayer is always smooth, tomtom loads up in about 3-4 seconds.
Remember the read speed is a lot higher than the write speed.
Generally you are going to be OK with a lower class. There are however certain things that a lower class memory card will limit, like HD video playback or a high speed game installed on the card (I think Asphalt is a good example of this).
You have to decide what your going to be using the card for and adjust how much you are expecting to spend accordingly.
Be aware that if you are going for a reputable brand then buy from a reputable site. Buying a Kingston or Sandisk from Ebay for a knock down price may mean you getting a cheap knock off. Tread carefully, and give this article a good read, give you a better idea of how easy it is to buy a knock-off card.

Hope this helps
I have been wondering the same because I have been debating on buying the new Kingston Class 10 16GB MicroSDHC card but if the HD2 can't fully utilize the speed, I will probably splurge for the SanDisk 32GB MicroSDHC card and get rid of a few of my 16GB MicroSDHC cards. It is kinda a hassle to carry around a card full of movies, card full of music, and a card full of pictures so I would love to get a 32GB when the price comes down a little more.
Anyone know any reputable sites??? I'm in Australia... So hard to find one to ship Australia and cheap!
I'm after the Kingston 16GB Class 10 card!!!
Thanks a lot for the tip guys. I'll definitely have to have a think about whether I'll need the extra speed, of the top off my head I don't think so but there's a good chance I'll be slapping a few PSX ISO's on the SD card in the future which I guess might be a factor!
@above - unsure of Aus sites, but stay away from ebay as another poster said. 99% of stuff from China (and a lot of the stuff local too) is cheap, low capacity memory hacked to appear to be 16GB and often enough they even include viruses on the damn things too!
UK buyers - Play.com are doing Class2 16GB's for £28 delivered (+Quidco cashback, www.quidco.com)

the only place in oz i could find a 16gb card for my hd2 was vodafone. it wasn't cheap ($89aud) but i've not had any issues with it. it says it's a class 2. i'm sure i read here on the forum that the class really isn't an issue with the hd2 anyway.

Umart sell the Kingston 16GB Class 2 Micro SD for $55. Unfortunately it's the only one they sell (no class 6 available on the website). Have purchased several times from them with no issues.
I did not even know there was a difference in classes. Glad I read this thread.
Class 10 SD cards
Anything over class 2 (which means it can read at a minimum or 2Mb sec) will be a waste of money on a mobile phone. Class 4 and up to the latest class 10, are designed for the speed needed on high end digital cameras that shoot HD videos.
Save your money, buy a good quality, genuine class 2 card, you will not see any difference on an HD2 with a class 10 card in it.
Some users reported that after changing their bundled class 2 card with class 6, music, album etc are up to 3 times faster in loading.
I just ordered a class 6 card to change it with mine class 2, will report about it.
Class
Im using the 16 gb kingston class 2 and it works like a sharm... if you are really picky you can go with a higher class card but be prepared to add some extra cash for a tiny bit of quicker preformance
Just so you will understand how the cards are built there is not much diference amongst the classes. This cards all have 16 Gb space whitch cover the tiny sd card. the diference is that on the higher class cards, the bytes will be shared out in a much more constructive way so it makes it easyer for the phone to read the data. we talk up to 2 seconds faster from the lowest class card to the highest class card. I belive thats from class 2 to class 6.
Good luck with your choice
So where are the good deals on MicroSD cards? I'm interested in at least Class4. What are you using with your GTabs?
I was wanting to hold out for a class 4 or better 32gb, but I don't think the included 16gb is going to last me much longer on it's own.
I have a class 6 8gb transcend card for backup that seems to read and write very well on the tab.
I usually just use google search and click on shopping to find good prices since they change constantly.
Thanks for the advice, I did see that shopping.google.com was probably the best way to find good deals.
Does anyone have any experience using a class 10 microSD in their GTab?
What are the differences between 4,6,8,10 sd class cards

Speed Class Rating
The Speed Class Rating is the official unit of speed measurement for SD Cards, defined by the SD Association. The Class number represents a multiple of 8 Mbit/s (1 MB/s), and it measures the minimum sustained write speeds for a card in a fragmented state.[11]
The following are the ratings of some currently available cards:[11]
Class 0 - These cards do not specify performance, which includes all legacy cards prior to class specifications.
Class 2 - Minimum of 2 MB/s performance. Lowest speed for SDHC cards.
Class 4 - Minimum of 4 MB/s performance.
Class 6 - Minimum of 6 MB/s performance.
Class 10 - Minimum of 10 MB/s performance.
Keep in mind that the class is based off WRITE speeds. I have a class 10 in my Vibrant, but only a class 2 in my Tab. That is because I tend to change what I carry on my phone more often than my tablet and thus it is noticeable. But if you are just going to load up 4 gigs of music and 8 gigs of movies and never change it, go with a cheap card.

I just ordered a 16GB class 6 for my Tablet. I'll probably be swapping out movies on a semi-regular basis, so didn't want to get just a class2.
Got a class 4 32GB from NewEgg. Works quite well and exceeds the rated transfer speed most of the time.
I'm using the Sandisk Class 2 32GB card and it's great. Sandisk cards always perform better at read & write speeds than the stated.
You're not going to notice any difference in speed..... not until you connect to a PC that is the only time when you will find a Class 2 is slower than a Class 6.
Using a class 2 16gb and seems to working fine
Sent from my GT-P1000 using Tapatalk
if i buy a class 10 card will the HD2 actually be able to read/write at those speeds as opposed to a class 6 or is there some internal limitation. i will buy a good quality card and test the speed when i have it.
i know that on a pc it will be faster but thats not what i want to know.
i intend to run android on sd and want the quickest card the hd2 will actually make use of.
I understand any above x 6 is wasted, use the search function suprisingly it works
Depending on what you're using the card for, you might be better getting class 2 or 4... especially if you go with Sandisk, which I recommend. Higher class cards have higher sequential write speeds, which is good for digital cameras or transferring large files, but they usually sacrifice their access times and random read, write and access speed. That's why more class 2 and 4 cards are compatible with WP7 devices than class 6 and 10, and also many have had issues with freeze-ups and performance issues when running android off a class 6 or 10 card when a class 2 or 4 performed better.
Higher class cards does not mean better in all situations, which a lot of people don't seem to know. Generally for phone use, class 2 and 4 are better. Class 6 and 10 are designed more for digital cameras or file storage. If you're going to be running apps or OS's off the card, or anything that needs to access many small bits of info quickly, Go with a high quality class 2 or 4 Sandisk.
Class ratings on cards are very misleading to people and people put too much importance in them... they only rate sequential write speed. It doesn't tell you anything else about the card, even though the other things are more important accept if you're using it for digital cameras. A new rating system needs to be made, especially since smartphones are so popular now and microSD cards are used more for cell phones than digital cameras now.
@zarathustrax: ok, thanks for the insight.
i will just get a good name card.

Someone managed to LEO T8585 WinMo show 32GB on microSD card?
i bought one but LEO displays cotinuosly 16GB without reset, then soft reset, then i make hard reset. I just wanna say WTF?
and custom rom is: HD2O v.19, rom is stable and wery good and i think its not rom issue.
thanks in advance.
I'm using a class 10 32gb card.
Not noticing any speed advantage over my class 4 16gb card, except for freezes because the 32gb card is not supported...
Thus you're better off using a slower, compatible card, as long as you want to use wp7
Some 32GB cards will only offer 29Gb of space. So do not only pay attention on the speed, the actual capacity will differ as well.
Some os's use 1024 * 1024 * 1024 as GB others use 1000 * 1000 * 1000, hence the difference with 32GB and 29GB (29.8GB). So no worries
Hi
obviously class 10 would be better but in the Note does it make much of a difference regarding speed/lag?
The class 10 32gb card is priced 15-20 more at a nearby shop so should I save the money and go for the class 4? Thanks
recently I switched from Toshiba class 4 16GB to Lexar Class10 32GB.
The 32GB class 10 is much faster when you copying files but for general use (photo taking, music playing, video playing, video recording)
honestly don't notice any difference
as said, a class 4 is suitable, only time you will notice a difference is usb transfer speeds
As darkinners mentioned, if you want the FASTEST, go for a class 10.
He also said it doesnt make much difference...so class 4 it is
I want to buy a 32gb memory card for my galaxy note. I want to know which class memory card should I buy. I am getting 32gb sandisk class4 card @1.9k and 32gb sandisk class 6 @3.9k. What benefits will i get with a class 6 card. please help !!!
You'll just be able to dump content faster to the card with a higher class.
by class 6 you must mean the new sandisk ultra series (red color cards).
if you gonna use your card mainly for storing apps and other such random access stuff go for class 2/4.
if its for HD video recording, large file transfers, etc (sequential read/write) go for class 6/10.
btw, for HD video playback even class 2/4 is sufficient. although there is an advantage for HD recording when going for higher classes.
also, if you meant the class 6 sandisk ultra, most of the reviews as well as users say that its much faster than most of the class 10 disks in the market, including class 10 sandisks.

Thanks for ur reply. Yes the class 6 card is the Red Mobile Ultra one. I wanted to know what kind of problems I may face with a class 4 card while 1080P video recording and is class 6 really worth almost double the price?
I went for a class 10 and it seems alright. Not overly impressed with the speeds though. But no issues with HD recording.

If you are shooting 720p or higher videos with lower class, you may experience stuttering in the video as the card isn't rated for high throughput data transfers. I'm not saying that it will happen every time, but that is the reason you should go for higher class cards if that is your main purpose. Higher class cards have higher sequential write speeds, which is what you need for saving pictures more quickly and for recording HD video. Lower class cards have much higher random access speeds, which are needed for someone who uses lots of apps.
so if you store all apps internally and keep the external card only for multimedia, you could blindly go for class 6/10. you get very fast data transfers also (PC to Note).
this class 6 mobile ultra is very new. it could actually be a good compromise between class 4 and 10. but don't worry too much. just stick to sandisk
you can also check this one. looks good and priced well for a class 10.

imho class 4 is enough for u to store mkv video file, it's for me.
Guyz I have decided for Sandisk class 6 card. But now the problem is as I see. sandisk 32gb class 6 @ 50$ and sandisk 64gb class 6 @ 111$. Out of these 2 which one do you recommend. THanks in advance !!!
If you can afford it then obviously the 64GB is better, but i would get a UHS-I if i were you.

Haven't got my Note yet, my question is regarding internal memory vs lower class external interm of speed as you said lower class will have stuttering and slow in saving pictures. What if I use my internal storage as the main temporary storage for taking HD video and picture, would it stutter like you mention?
Then when I'm done recording, I just transfer the recorded HD video to my external card. Would that make scene?
I want to use my internal memory as a temporary storage and will move my data to external card when doing house keeping. Would clearing internal storage enhance overall phone speed performance?
