Micro SDHC Compatibility

Hi,
This may be a silly question for some but i've searched around and i still cannot find a definitive answer anywhere with regards to micro sdhc cards being used in the samsung galaxy s. If i was to purchase a micro sdhc card am i going to need some form of adapter? I only ask because most places i shop around only sell micro sdhc cards.
It was my understanding that the galaxy s only had a micro sd slot which is what is currently confusing me.
Thanks.

it supports up to 32 GB of microSD
anything larger than 4 GB = SDHC support

Galaxy S supports Micro SDHC.
(Allgamer basically said that, just in a slightly roundabout manner).

I'd like to know (please), whether the device can perform all functionality such as record hd and playback 720p movies over dlna from a class 2 card? I want to order a sandisk 16gb card, but would save the pennies on a class 4, if a class 2 performs well.

you could still get a class 6 16GB cheaper than getting a Class 2 16GB Sandisk, if you buy from other brands like Transcend (excellent), Adata, OCZ, Kingston, etc....

If it helps, I'm using an old class 6 Transcend 8GB. Bought for a micro DVcam (hence the need for class 6) last year and think it was around £10 then - possibly cheaper now?

You can get a 8 GB SDHC from DealExtreme.com for < $20 any day of the week.

Lexar Secure Digital 16GB class 10, 133X
How about this one?
Lexar Secure Digital 16GB class 10, 133X
Tip: SDHC
Size (MB): 16384
Rate (MB/s): 20MB/s
Class 10
Is Lexar a good name for memories?

I am currently using 4 GB Micro SDHC card with SGS.It is my old phones (HTC HD Mini) Micro SDHC card and it is working great.

I just bought this Wintec 16GB class 10 from Newegg.com... now whether it's an actual class 10 that's to be determined cause it's in the mail. But for $30 you at least get 16GB.

anyone try a-data 32gb class 10?
I'm curious if anyone try a-data 32gb class 10?
half the price of other 32gb cards.
the reason I ask is many folks report issues with hd cams.

not that i know of, so far all the confirmed legit SanDisk 32Gb has been Class 2
some places advertise they have Class 4 SanDisk 32Gb microSD but.... the picture and the price listed are those of a Class 2
some people have confirmed the Class 2 SanDisk 32Gb microSD can write 4Mb/s but that was on a new empty disk test
i would like to see some test done on 60% full 32Gb Class 2 SanDisk microSD to see if it can sustain a Class 4 write after half full, being a Class 2

check this review link http://www.testfreaks.com/blog/review/review-of-kingston-class-4-32gb-microsdhc-card/
should buy Kingston or Sandisk 32GB MicroSD for my Samsung GT-i9000 Galaxy S
or any other brand?

How ?? A 720p video at maximum quality usually takes around 1.5 ~ 1.8MBps, so a Class 2 (2MBps guaranteed write speed) in theory should be quite sufficient, at least with my Class 2 cards I haven’t had any trouble recording 720p video.The Sandisk 16GB Class 2 I have can be written to at a minimum constant speed of 8MBps (has around 4Gigs of Data on it already). And the Nokia branded (not sure about the actual brand) 8GB Class 2 which I got with my previous Nokia phone can be written to at 4MBps + (has 7Gigs of Data already). So IMO as long as you go with a name brand you should be able to get more than 2MBps writing speed which should be enough for 720p video.
You might get better speeds when transferring large files to your phone, but how often do you do that ?? And if you do that over Wi-Fi or Bluetooth like I mostly do, it won't matter at all. Spending on anything above class 6 (e.g Class 10) IMO is a total waste of money. I use a class 6 on my DSLR to record 1080p video, haven't had any issues with it so far. So I hardly think Galaxy S can exhaust a Class 6 card, or even a branded Class 2.

video is a secondary use
i use it mainly for applications and data transfer (portable hard drive), the faster the better, the less noticeable lag, and speeds up Titanium Backup quite considerably

The recent batch of SanDisk microSDHC cards (seen here in Brussels in Media Markt and Fnac) has Class 2 marking changed to Class 4 (8, 16 and 32GB). They have exactly the same packaging down to part numbers. That's mine for example: http://i37.photobucket.com/albums/e62/ping_ling/android/microsdhc.jpg

Kingston 32gb class 4 vs sandisk 32gb class 2

hey guys... how does a kingston 32gb class 4 compare to the sandisk class 32gb microsdhc card?
in terms of performance? i know kingston is a reputed brand....but sandisk usually ranks quite high in the memory card dept....

sandisk may be good now but their 16gb were pure trash.. i will never buy another sansdisk after i had 4 16gb cards fail on 3 diff phones..
i now use a-data 16gb class 6 cards.. never had a failure.

I just got a SanDisk 32GB card in an AT&T branded packaging from ebay for $70 shipped. I didn't want to risk buying Sandisk packaging or bulk packaging at lower price due to too many fakes. The AT&T branded packaging and the Verizon branded packaging are guarantee legit as it's a regional packaging only available in the U.S. After receiving the card, I tested it with H2testW 1.4 The performance is 5.47MB/s write and 14.8MB/s read. The total test time is a little over 2 hours and 7 minutes and it passed as a legit 32GB MicroSD card. This is easily a class 4 card. I read benchmarks that the Kingston's 32gb write speed is slower than Sandisk but the read speed is faster. I do notice one flaw that I was not able to flash the ROM from this card. I copied the same file to a 2GB card and was able to flash.

Is a microsd class 2 enough for recording hd videos and running apps?

Im planning on buying a 16 gb microsd card but all i can find is cards class 2 is that enough for recording 720p and loading applications installed to the SD card ? keep in mind that i also plan un buying a optimus 2x which has 1080p recording
Which brand do you like better? sandisk? kigston? trascend?
I read that sandisk class 4 cards are REALLY good but they dont show up in their website or amazon :/ , it seems they only sell class 2 cards, and kingston offers cards class 10 and 4 , class 10 seems a little excessive

Class 4 but really class 6 is what u need class 2 will die
Sent from my GT-I9000 using XDA App

yeah minimum a class 4
class 2 is just a pain, it will make you want to throw the phone away, and explode it into a million tiny bits
class 6 is the normal speed for a fluid experience

Im using a Sandisk 32GB class 2 card, it writes at 5~7Mb/s depending if its a large file or several smaller ones and read as higher than 15Mb/s

If you are getting a 16gb card, or less sandisk, kingston or toshiba, class 2 or class 4 offers similar read/write speed, although the toshiba and kingston is a little faster, the sandisk is much stable.
Read is about 11-14mb
write is about 8mb
I had a toshiba 16gb class 2 in my i9000, it plays 720p videos without any problems, now i am using a lexar 32gb class 10, results aren't any different.
Hope this helps.

lexar 32gb class 10? jezus christ you must have payen an arm and a leg for that ****.

Approximate usd 85.

The class designation of SD Cards ONLY represents the sustained WRITE speed to the card in MB/s. So, class 2 means it can be written to at 2MB/s, while class 10 means it can be written to at 10MB/s.
The designation has no reference whatsoever to the read speed of the card. So, basically every response stating otherwise in this thread is wrong. You should be able to get suitable sustained read speeds out of any class 2 or higher SD Card for the purposes you will be using it for. It will just take you longer to transfer the data to it in the first place. As for video recording from your phone, class should should be plenty as I'm pretty sure 720P comes in under 2MB/s.

Wow, yea. Just that i seen some online shops which class 2 32gb cost 100$
But on amazon the lexar class10 32gb is really cheap...

Electroz is right. Its only about transferring and stuff.

The speed of the card used in the phone does not make much of a difference, its onlt when you transfer data to and from Pc, but its always best to get the fastest available, if the budget is the main problem, consider getting a kingston or toshiba, but make sure you get one that is made in japan, as the taiwan version is a litttle slower, japan version are becoming harder to get now, since the japan factor has transferred their production to the taiwan site.
The classes stated on each card is only the minimum it will reach.
Class 2 at least 2 mb read/write
class 4 at least 4 mb read/write. etc.
So it can be anything above the actual figures.
For more info on microsd, see my link in the sig, although its a little out dated.

The actual retail price for the lexar 32gb class 10 is 149 usd.

No problems with 32GB Class 2 here, it can record and decode 720p just fine, and there is nothing else as intensive as those tasks that you'll be doing with this handset (may not be enough to support 1080p in future handsets, but that remains to be seen).
Don't buy into this rubbish about needing Class 4 or 6 cards, unless you regularly load very large numbers of small files to your card, in which case you may want the higher write speeds.

when you run apps and/or games off the SD (App2SD) the slower the card the more time it takes to have a fluid experience, specially heavy stuff from gamesoft, or simply opening the application manager and waiting for the icons to load
repeat the same tasks with a slower card vs a faster card and you'll see the difference
of course you'll not really see much of a difference, unless you card is more than 50% full, and have over 300+ apps installed

You can buy a Kingmax 16GB Class 6 at Amazon for £43. I didn't had any problem to find it. Class 6 is much better. See you - Frank

If your getting cards from a non generic name brand, the read speeds should be around 15-25Mb/s , My class 6 card actually had a slower read speed of 15Mb/s compared to my Class2 ( 28Mb/s )
At the end of the day the difference between loading something was barely noticeable even skipping to different portions of a 3.7GB movie, Im guessing the phone it self is the bottleneck and not the card.
1% or 99% full should have ZERO effect on the read/write speed this is not some mechanical drive nor having 1 or all the apps in the market.
EDIT:
Again the class rating is only a rate on what is the minimum write speed the card can handle, sandisk rates their 32GB at class 2 when it writes at 6-7Mb/s ( making it class 6 ) on the phone and about 10Mb/s using a card reader ( making it class 10 )

yeh, buying from a local store is cheaper, from the same price of a kingston 16gb class 10, you can get a 32gb class 4, but the fastest microsd on the market is the kingston 32gb class 10, but stock is very limited due to high prices, and you probable need to place an order and pay in advanced, i'm still searching for one, since the last time i heard about it about 9 months ago.
adata are the cheapest cards now, but the speed are rather slow, compared when they only released the 8gb about a year ago.

what are you guys using for sd cards?

I'm guessing some manufacturers cards work better, faster? I'm seeing class 4, 2, 10! 32, 16gb. Are there brands to just stay away from? Just scrolling through amazons 32gb selection reviews I'm in doubt about quality, or fake knockoff cards.
Thanks !

I got a 32gb class 10

what brand was it?

Lexar 32GB Class 10 for $100

I bought a Patriot 16GB class 10 for $40 on Amazon...Never heard of the brand, but its been working solid since I got it and speed tests confirm its class 10

of all the different brands of thumbdrives i've owned, i have an 8 gb Patriot that connects to every PC i've tried it on. Newegg doesn't sell it anymore.
i did find a Patriot 8 gb micro SD though!

Using an A-Data 16GB Class 6. Just got it today and it's working great. $30 on Newegg
http://www.newegg.com/Product/Product.aspx?Item=N82E16820211378

Here's a good deal from amazon right now:
Patriot Signature 16 GB Class 10; ~$30
I would stay away from Class 2 or 4 for HD videos since I am concerned about transfer rates. Maybe someone else can comment?

seems like if we want to play video or high speed transfers the choice is a class 6 minimum. I went ahead with qubits recommendation and went for the lexar class 10.
I was testing an 8gb a data generic card, and a few smaller ones without a problem. Some post earlier in the board said,"go big, or go home.' That stuck, so I went for the 32gb. I sure did t want to get a huge card that wouldn't play well with the xoom. So another vote for the lexar.

A-Data 16GB Class 6, works great for me.

Lexar or Samsung 32gb MicroSD Card Recommend?

Hi guys i am looking to buy a 32gb Class 10, MicroSD card for my Desire, i am planning to partition it so i can have more internal space. After searching the market for a competitive price, i have came down to 2 options:
Lexar 32GB Micro SDHC Class 10 Extreme Speed
Samsung MB-MSBGAEU 32GB Class 10 Micro SD Card
I would appreciate if users here can recommend me which one i should go for and why (if owned either and used) ?
Thanks alot

As far as I know, many of the higher class cards have been produced by biasing performance to continuous read/write speeds, for use in camcorders/cameras etc so they can record ultra HD or burst capture etc. HOWEVER, for use in a phone, which needs greater random read/write access they can suffer compared to a regular class 4 which is a better balanced card. There is a lot of this going on in the HTC Mozart pages here on XDA, where I've been spending time (had a Mozart, ROM'd it and gave it to my girlfriend, she loves it).
Many people have tried different 32gb/16gb cards, different classes from 2-10 and the results have been surprising. WP7 seems to be unusually fussy about the cards that will actually work with it, and the only card guaranteed to work everytime is SANDISK which says a lot about the quality, and people have been finding that performance with a Class 4 SanDisk card is better than performance with a supposed Class 10 card by another manufacturer such as Integral, Transcend etc or even Samsung and Kingston.
In the end I bought a 32gb SanDisk Class 4 off Amazon, for a lot more than they are on eBay at around £28, apparently there are loads of near-fakes on eBay (only way I could guarantee it was genuine- the chinese are using genuine 4gb SanDisk cards and then re-branding and re-coding them as 32gb, the card thinks it's a 32gb, reports that it's a 32gb card but obviously runs out of room and has errors as soon as you try to put stuff on it).
Hope this helps- generally you get what you pay for and if it sounds too good to be true it usually is.

I bought yesterday a samsung class 6, 16 GB micro-sd card.

i know this post is about 20 days old, but maybe you haven't choosen a sd card yet
i first got a 16gb lexar class 6 card -> everything was fine
now i got a 32 gb samsung class 10 card
and i must say there is no remarkable speed/transfer difference
so buy a card which is class 6 or higher and everything should be fine

I thought that the maximum allowed for Desire was 16 gb. Mine is 16 gb (Samsung), with good data transfer performance. By the way, in your situation I would go for Samsung.
