I am thinking about purchasing a 32Gb microSD for use with my galaxy S.
My concern is that, is this too large? Are there any bad side effect like it being too slow to display picture/start up scann/run applications?
Which brand? That's probably more important for the speed than class (a class 2 Sandisk is often as fast or faster than a class 6 from a lesser brand).
The capacity of the card shouldn't affect the speed during most situations. However the phone does scan for media each time it is turned on or after disconnecting from USB connection (Kies or mass storage), the amount of time this takes depends on:
-the amount of media stored on the card and
-(probably) the read speed of the card.
Note that class rating is minimum write speed - so it's not a great indicator of real-life performance.
Also note that some too-cheap-to-be-true cards are actually smaller capacity cards that report larger capacities to fool the customer.
BTW where are you getting the card from (I want one as well ).
Hi flamingpitofhell,
I am looking at Sandisk as well and most likely get it from their online store. I am trying to find more information whether it is worth the trouble.
I don't think Sandisk sell class 6 cards (yet). Buying from their online store's also more expensive than online retailers (I can get one in Australia for AUD155, which is ~USD137, cf their RRP of USD200).
thanks for the pointer. will look around for local stores here in Thailand.
Which city in Australia are you in? I studied in Perth more than a decaded back.
I'm in glorious Melbourne mate, haven't been to Perth yet
the only LEGIT 32GB Sandisk available right now in the market is only Class 2
if you read anything else, it is FAKE, specially from eBay
wait until the other microSD manufactures start pushing out 32GB on class 4 or class 6 before buying.
i'm using 2x 16GB Class 6 until the 32GB class 6 becomes available.
I'm using Class 2 32GB card in mine, its fine.
Its slower when you're transferring to the card from your PC, but for most people thats only particularly problematic the first time (loading music collection), after that you'll not really notice a difference in the phone (the read speeds are basically the same, and the phone can neither read nor write to the card faster than a Class 2 card can cope with). You can see it in the benchmarks taken post-mimocans fix - Class 2 cards are no slower than any other Class within the phone.
Grab one now and be happy.

Where did you get yours from and how much for. I`m interested in getting one myself.
Thanks
my local stores already carry the real Sandisk 32GB class 2
too slow for my taste, i like to run Apps from the SD card, also use it as a SWAP partidion to prevent the LAG problem people complains about, it's a very easy fix

i wonder what would be better a 16gb class 6 or 32gb class 2...
is it worth sacrifising double of the memory for the speed?

it depends what you are trying to do
if it's just to listen to mp3, then Class 2 is fine
if you want to run games, software, watch movies, use it for SWAP drive to have no lag, then minimum a Class 6
Class ratings don't really seem to have too much of an effect on real world performance: http://forums.whirlpool.net.au/forum-replies.cfm?t=1468705. Just discount the last result from the SGS (it's most likely mistaken for the internal SD).
i rather trust my experience coming from PalmOS + WinMb where real life situations using a class 4 or slower cards, made a huge word of difference when launching applications from SD and watching movies from SD
funny enough the numbers reported on that topic shows SGS i9000 to have the fastest speed even using the same card that got lower speed on the other phones.
which seems to point out it's directly proportional to the CPU speed, and the multitasking software running in the back end.
however as you see on those test itself, there are speed differences between class 2, class 4 and class 6
the same class # can not be compared to another class # of a different size,
if you imagine a hard drive, the bigger the hard drive the more layers/disk area it has to read, the same is true even for static SD cards.
however as pointed on those test Transcend usually has the fastest SD cards in the market, that's why i always buy that brand for performance, using a 16GB Transcend myself, waiting for the 32 GB class 6+ to come out
Adata has 2 lines, the performance line, and the standard line
if you want speed get the performance SD cards
Kingston and Sandisk are mostly standard speed, they don't release much performance level SD cards anymore, but they do have lots of those on USB sticks.
I tried my Brothers Sandisk Class 2 32GB and it worked perfectly.
Granted it's not as fast as my Sandisk Mobile Ultra Class 4 but that card flies anyway.
Certainly for recording your large movie files taken with the camera it's no different in speed than using the built in SDCard on the phone.
I have no problems watching 720P video on my phone. I have no problems launching applications either.
So much misinformation...
of course there is no problem, the issue here is getting the top performance, any SD card will work just fine.
it's just a matter of how fast/slow are you able to torelate
The only time you will notice any difference in speed is when transferring data to and from the card.
However, when you have double the space of other cards to consider speed should not be a deciding factor.
I'm already looking to get the Sandisk Class 2 32GB card. It will store all of my work files normally kept on my Laptop.
My Sandisk Class 4 Mobile Ultra 16GB will be my spare ~ should the larger card fail...
Thanks for the information s everyone.
Sent from my GT-I9000 using XDA App
I have the 32GB sandisk card and works perfect. I have a 720p mkv file and my music on there. Playback was superb for the video with no noticeable lag. Mind you the card isn't anywhere near full yet. From my limited knowledge of sd cards, they put data on the fastest part first so the fuller it gets the slower the card is likely to get..
My plan is to put movies and songs on the 32GB file and reserve the internal 13GB for capturing video and taking pictures on the phone.

Hi, sorry if this is a double post. I did look around but could not find much info.
I'm interested to know how well the new 16GB MicroSD cards work on the Xperia. Anyone using one of these? My main concern is that they all seem to only be class 2 atm. Is this too slow to run apps and my videos stored on it etc?
Should I wait till a class 4 16GB card comes out?
Thanks
Edit: I also noticed that SanDisk has a “Mobile Ultra” memory card range. Only up to 8GB though. Anyone using one of these? Is there a big difference in speeds?
i don't think it matters in a phone.
I ordered the eact same Mobile Ultra card today. Should be here saturday, so I will tell when I get it. But assuming it's Class 6 card, it should be fast. I wouldn't go with Class 2, since it's slow. But as Jabe says, it might not matter on the phone.
So as at now no one's using a 16GB yet?
Give me a week or 2. I'm planning on ordering the Sandisk one.
Sandisk Mobile Ultra is good, and it's what I am using for X1. Since it's class 6, the read/write speed is about 20/16 mb/s, which is much faster than class 2. If you wanna watch video storaged in card, this one is your first choice.

Note that the speed in the end is depending on the host itself. If the host is slow, even if you use class 6 memory card, it's not going to make any difference. Personally I believe the phone itself would be the bottleneck and not the memory card.
I know it's not totally relevant but just for reference, take a look at the link below. As you can see the speed of class 2 and 6 are pretty identical as it's limited by the host. This is even with a dedicated memory card reader. Compare the 2nd and 4th entries from the bottom.

I'm using a 16GB Class 2 at the moment. No probs with apps or music. But I have no videos on the card...
with normal sd cards the pdas were mostly not able to transfer as fast as the sd card supported
as the sd interface in onchip and not that fast
would like to see some tests if the same hold true with newer pda's and class X microSD cards
anyone able to follow this up yet?
I'm using a Sandisk 8gb Class 4 HC. No problems with speed or data read/write (on the phone itself).
Using the phone as a disk drive though (not activesync) is noticeably slower than using a USB adapter, *suggesting* the phone itself is the bottleneck?
I'm using a SanDisk 8GB Class II Card and I had no problems with photos, videos or music so far.
Don't think a Class 4 or 6 is worth the price in a mobile phone.
I got my 16GB Microsdhc today. And everything works. Sad thing is it only shows 15GB.
I find no difference in speed between my 8G class 6 and 16G class 2 (both from Sandisk)

it's 15G probably because of the way how "G" is being calculated. 16,000,000,000 = 16,000,000,000/(1024*1024*1024) = 14.9GB
im using a 8g class 4 card, music, apps and vids work great.
just a quick question, the x1 has a sd card limit of 32g, when a larger card comes out like the 128gb card that sandisk has said will come out, could windows mobile have a update so that it can read it or is limited to the reader hardware inside the x1
I have 2 cards: Sandisk 16GB Class 2 and Kingston 8GB class 4.
I use Sandisk in Xperia, and the speed is more than sufficient. It reaches 12-15 MB/s writing on USB adapter. Reading - it's no problem reaching even more. So it's ok, speed wise.
I don't think you would need more speed in Xperia )
There's no HD video recording option in there )
one can use pocket mechanics to benchmark the sdcard speed
if the results are lower i would suspect it show the bottleneck speed
of the sd interface of the qualcomm cpu in x1
I have a 16gb micro sdhc and some .avi videos lag (highish quality). Specifically, top gear season 12 episodes from finalgear.com. it might be the divx client though, Im using the WM 6 Pro version available on the divx website.
I created videos showing the dramatic difference (before vs. after) but then realized this site does not allow me to upload videos (and I am too lazy to set up a utube account).
The 16GB Micro SDHC card that comes with the T-Mobile HTC HD2 is only Class 2 and is a very SLOOOOOWWW card (also class 2 cards are CHEAP, that is why it is INCLUDED FREE). If you watch the Transformer movies installed on that card you will discover there are a few times during the movies where the screen momentarily freezes. Also if you have alot of songs on the card, when you scroll over to the media player you will see it takes forever for the media player tab (about 45 seconds) to display anything. Even a game that comes with the unit repeatedly freezes and is not playable because of the speed of the card - under games, try the game called "Ferrari GT Evolution". It is a great game but it is unplayable on that card.
I purchased a 16GB Class 6 Micro SDHC Card and it came today. I copied everything from the old card to the new card. WOW, WHAT A DIFFERENCE! It is about $60 but is makes a VERY big difference in performance for everything mentioned above. For instance, the Ferrari game mentioned above does not freeze at all (and loads much faster) and also when I scroll over to the media play tab the delay before that tab becomes useable is only about 3 seconds.
If you want a SAFE great way to really improve the performance of your unit, replace the old crappy Class 2 Micro SDHC card with a Class 6 version. WOW.
(BTW, my main reason for getting this card was also that it took too long to take a photo and then to be able to take another one immediately afterwards. Now that is MUCH faster as well. A workaround would be to not use the card for picture storage but I prefer to put them on the card.)
I have been using a 4GB class 6 card I had laying around and I have seen a difference as well. I copied all the data from the 16GB card to my computer then copied it to the 4GB card to start out with. I saw a big improvement in the momentary freezes that occur when navigating the UI, music indexing and video playback. After using that card for a couple weeks I copied everything back to the 16GB card after formatting it and popped it back in to see if it was a placebo effect. Things were noticeably different, it just felt more sluggish at times. The Class 2 card isn't bad and it isn't the whole problem but getting a better card does change things a bit.
I did pick up a couple 8GB class 6 Sandisk cards for about $10 not to long ago for my camera. The 16GB and 32GB cards aren't as economical yet. The improvement is worth $10-$20 dollars to me but not $60.

It'll be printed right on the front of the card...a little number inside of a circle. If you dont see one there, odds are it's a class-2

Class 6 vs 2 Photo... (Micro SDHC Card)
There is no such thing as a Class 10
Look at the photo (CLICK ON THE PHOTO TO ENLARGE IT AND SEE THE DIFFERENCE) FOR THE Speed Class Designation. I guess the standard spec does not say which way is right-side up for printed labels!
Class 6 is the highest speed currently. There are 32GB cards out there (which the unit can support) but they are VERY expensive. The Class 6 card I bought was somehyting like $60 with the shipping from Newegg.com.
Also notice that it is such a damned nightmare to be able to read these ever so tinier labels on everything out there! (Or maybe it's also because of my age.)
It is true, also, that those without the class specification are much older - and slower, I guess they should all be lumped in presumably with class 2

thanks for this thread... i totally didn't realize there were speed diffs on microSD cards.
so a few questions then:
1. the new 32GB sandisk microSD is only class 2... i assume no other manufactures are out yet, especially with a class 6 or 10. this is the very end of the SDHC standard. the next upgrade will be all SDXCs.
2. will a class10 be better than a class 6? i always thought that there are spec. limitations to SD card readers itself. does anyone know what the max limit of the HD2 SD card reader is? class 6 or 10? because if it's class 6, then buying a class 10 would be useless.
i remember that older SD card readers can't read the SDHCs.

1. I haven't seen any class 6 32gig cards but there will be some eventually.
2. Technically class 10 is faster than class 6 but unless you run everything off your sdcard and have a ton of music/video I doubt it would be worth it. If you were going to be using a 32gig card then a class 10 would probably be worth it, though I don't know if the HD2 supports that speed.

Thanks for the "usual" lolol...
To be honest I've got the class 10 Panasonic, and a class 6 Kingston, (both 16gb [32gb models are ridiculously expensive]) and when you run them side-by-side in a phone, there really isn't a difference in everyday use that I can tell. Class 6 is plenty fast for a phone. But there's always people like me in the world who aren't afraid to fork over the extra money to see if the latest tech will get me a little extra speed.
For those on the ropes as to what to get: if your just listening to music, Class 2 is good; for video, class 4 is good; if your non-stop music and video all day everyday work and play, and have some extra cash Class 6 rocks.
For all of you nut jobs like me who care about the extra microseconds of speed, lolololol, and have the money to spend...get the Class 10...
~Jasecloud4
the first thing i did for my hd2 was upgrade to a class 6 from previous experience with rooted android handsets (where upgrade to class 6 is always recommended
would a class 10 or a class 6 improve battery life?
Thanks for the thread and the informative posts, I guess I will make sure to get at least a class 6 for my media heavy device.
Also, if I were to buy one, which companies are reliable? Or are they all pretty much the same? I've only heard of SanDisk and Kingston because I've met the co owner of Kingston and he gave me some free stuff before.

I would just stick with sandisk or kingston anyway, they're both as reliable as any, and usually priced right along the lesser-known maufacturers.
So for anyone who has used both a class 6 and class 10 card IN THE HD2, is there a speed difference? I have a paypal coupon code that is good for 25% off, and am eyeing some of the class 10 kingston cards on ebay which would come out to about $74 with this coupon code. Not very much more than a class 6, course i could just use the coupon code for a class 6 off ebay too. I would like to go the 32gb route, but seems everything 32gb is class 2 =(
So I downloaded this app call H2testw.exe to test for legit sdcards but it also tells the read/write speed as well. I am testing my 8gb and 1gb cards. I set it to write a 300 mb files to the card and verify it.
Info about Android running on the two cards:
8gb = lags coming out of sleep, touch screen freezes, write~7.5 mb/s, read~12mb/s
1gb = no lags, no touch screen, write~4.3mb, read~13mb/s
I'm confused. The read speed is almost the same yet the 1gb microsd is more responsive running MDJ android compared to the 8gb microsd. Any thought?
UPDATE: Maybe this is what's causing the problem. Stolen from Engadget.
What we've learned from our tipsters and from documents culled from Microsoft, Samsung, and others is that the big issue is random access performance -- a figure that isn't taken into account in a card's class rating. Ironically, Microsoft discovered in its testing that cards with higher class ratings actually performed worse on Windows Phone 7 because the tweaks card manufacturers make to achieve high sequential throughput can actually hurt random access times. There's some rocket science involved here, but basically, it's a tradeoff and a bit of a gamble -- if a manufacturer tunes a card for a high class rating, it takes more time to access the first byte at a new location on the card because it's optimizing access for that area of memory, but once it does that, it can blast sequential bytes at very high speed. If you've got a lot of small reads or writes you need to make to different files at different locations in the card's memory, though, you really start to suffer. Cards with lower class ratings tend to spend less time optimizing sequential access prior to the first read / write operation, so it can move around the card (that is, access it randomly) much faster.

Btw, guys...
all sd cards are not created equal. all sd cards of the same CLASS are not created equal.
Check out the ongoing drama with win7 phones with SD slots....
class measures throughput, what affects the SOD and related issues is random access speed, not throughput so much.
It's just my 2 cents, but I've tested Class 2, 4, and 6 MicroSDHC cards and found very little noticeable difference once Android is fully booted up and running on the HD2. Moreover, none of the cards create screen freezes or SOD issues or high battery drain problems here. That said, I have noticed that the actual boot time and file transfer speed (from the PC to the card) can be faster on average with quality higher class rated cards of the same size. Also, I've found that the larger the card size, the longer the android boot time, no matter the class. Guess that makes sense, as the system need to read more sectors with larger size cards. Please note that I've only tested Sandisk, Toshiba, TopRam and Samsung cards to date. What's kind of strange is that the Class 2 16 & 32GB Sandisk cards run just as well or slightly better for some reason than some of my higher class rated cards. Go figure...
As far as issues go, I recommend only using quality brand name cards, no ebay fakes or cheap no name brands. Also, I've had great luck formatting all my cards with SD Formatter v2.0 and v3.0, using the quick format mode with the standard 32kb cluster size.

Could this be the reason why class don't matter on hd2 android? I mean even some class 4 & 6 have lag and sod problem. I pulled this bit from engadget. It's an article on wp7 and memory card issues.

Hey I know that the main problem with the Evo camcorder is in how it is encoded and the main restriction holding back the quality is the speed of the sd card. I would like some feedback for those of you who upgraded their sd cards on whether it has had an impact on video recording.

currently I have the stock sd card, but I'm considering upgrading if there is a significant difference in video quality

Hey I know that the main problem with the Evo camcorder is in how it is encoded and the main restriction holding back the quality is the speed of the sd card. I would like some feedback for those of you who upgraded their sd cards on whether it has had an impact on video recording.
Thanks
currently I have the stock sd card, but I'm considering upgrading if there is a significant difference in video quality

I've had two memory cards besides the factory 8GB. One was a Sandisk 16GB Class 2 and the other is a Lexar 32GB Class 10. Video recording on the class 2 cards while panning at a good clip introduces artifacts into each captured frame, and the fps drops considerably. However, with the class 10 card, both of those are reduced significantly. The artifacts are virtually non-existant and the fps slow down only happens when moving the camera really fast.
I would definitely look into getting a class ten. Two cards that people are going with are the Wintec 32GB (avoid the 16GB) and the Lexar 32GB. Check out www.provantage.com for the Lexar card and www.newegg.com for the Wintec one.
I'm using a class 10 16gb, After looking through my videos, I would say there is a small improvement in quality. Mainly in the old videos I noticed every once in a while it would get pixelated, the new ones don't and theres less of a grainy look. One MAJOR thing I want to point out is on the old 8gb class 2 I was using a sense camera now I'm using the asop one in CM7.
I would just go spend the $30 and get a better card, it'll make your life better in every way!
anyone know what the threshold is for sd card classes regarding quality? in other words, besides faster data transfer speeds to another device what is the lowest class # needed to see improvement before its overkill?

Seems class 10 works well. If I get time at some point I'll try to do a test with similar lighting and such. I have class 2,4(?)6, and 10.
Also one point I want to make is I got my 16gb class 10 on newegg for $30(wintec, it has horrible reviews but mine works fine), but theres a ton of others and check out the accessories forum a lot of times people will post up when they find a deal.
If you just want more speed theres lots of 8gb class 6 for under $15. Micro Sd cards have dropped a whole lot in a short time

i dont care too much for faster data/file transfers to & from a computer as id rather spend the extra money for more storage than on a class 10 when a class 6 improves video recording just as well.
on the other hand, if apps or videos that are installed onto an external class 10 sd perform better than class 6, than itd be worth the upgrade, but im not sure if the phones processing power is the limiting factor or the weakest link, if that makes sense.
any one else care to share their thoughts of say a class 6 vs a class 10. I still have the stock class 2 in both my evos and video quality is very unreliable.
Thanks
Sorry if this was already asked but I tried searching. What type of class micro sd card will I actually benefit from? A samsung class 4 32gb is out there for a good price but if the tablet will actually take advantage of a class 10 I would get one of those.
for the most part it will not. Except in moving large files to and from the card.maybe playing movies from the card.but even movies are OK on 4.6 class cards..if you could run apps or have there data from SD card then it would be a big improvement. I have used a 8 gig class 4 and now have a 32gig class 10.can't tell much difference other then when pushing roms and other large files to my tablet over USB.
I would say get 6 minimum but if you have the cash faster is always better. Just don't go out and spend the money if you have a class 4card.
Im sure you will hear diffeent from others.
Not really. I have 5 sd's, and no difference between class4 and class 10.
Up to a certain size that is. Anything more than 16gb, and I would move to a class 10.
Rumor has it, that you can run a 64gb. If you partition it with Partition Magic.
I think it depends on what you are using the card for. I don't think it is the tablet that would take advantage as much as a particular app that would. If you were using apps that required fast read/write access to the card (and you were actually using the card as opposed to the internal memory) then the faster card would be best. Keep in mind that not all class 10s are the same so also make sure to look at some of the benchmarks for the different cards. I know in terms of photography and hd video captures that a higher class card really does make a difference...but that is just an example of a real use application.
Hope that made sense.
