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
And here's something on it http://forums.sandisk.com/t5/Mobile...ught-new-card-is-this-fake/td-p/189102/page/2

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

Ive been reading good comments about the sandisk cards, but they only sell class 2 cards :/ , what brands are u guys using?

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.

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...

Anyway, i got a 16gb class2 card (a-data) and i can play 720p and record just fine...
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.

32gb MicroSD advice please

I am looking at either a Lexar or Samsung both class 10, both around £37.
any advise as to which one is best based on anyone using.
The other question is do you need to format before use?
At the moment I have a 16gb but it is 98% full. Never chenged a card before was planning to copy the old card into a folder on laptop and then back onto the new card.
Any advise welcome,,,,,,,,

Go with transcend. If they have 32gb class 10.

They only do a 16gb class 10. I looked for Transcend first as I prefer this brand.....

I like transcend more than anything else.

I never had luck with transcend, i have a sandisk 32 gig which works great,
i had a kingston 32 class 10 within a few weeks it just burnt out on me it stop reading and wouldnt want to format or anything

I'm also looking for a 32gb micro sdhc for my HTC Vogue. I currently have a Sandisk 16gb that is nearly full. Earlier today I stumbled onto this thread from here at XDA...
http://forum.xda-developers.com/showthread.php?t=1150369
I found it quite helpful. I hope you do too.
I was surprised that class 10 cards weren't the best choice for the things I use my Vogue for.
Here is a passage that surprised me...
"Class 2 and 4 cards have better random access speed and random read/write than class 6 or 10 cards in general. To get higher sequential write speeds, manufacturers sacrifice the random access speeds.".

I would agree with Random read/write access might be better in Class 4 cards than Class 10...
But arent we forgetting that most of the applications are read more than Written when u open it.. I think a faster read speed with lower write speed would still be better than having lower read/write all together...Not unless you are downloading a torrent in background and running HD game with it... infact in that situation.. both cards will fail badly..

I prefer Sandisk.
A class 4 should generally give proper performance... 10 seems a bit overkill imho.

I've used the 8GB class 4 memory card that came with the Sensation for a while, and after switching to a 32GB class 10 Lexar I must say - it DOES make a difference. It's a totally different experience.

Been using SAMSUNG ESSENTIAL 32GB MicroSD for more than 2 months without issues. It has helped me to parallely download videos from tubemate in high speeds. Good writing and reading speeds. No slowdowns/jatter in 1080P recording which iam always using to cap my child.

Just bought a 32GB Class 10 Samsung card from play.com for £34.99. Working great so far!

I got the 16GB SD card for two reasons
1. The 16GB has a faster write speed.
2. I didn't have $90 to spend on the 32GB.

Oh also I did not pat $55 for the 16GB

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.

[Q] Is pulling from micro sd card as fast as internal memory

(1) I'm going to buy a galaxy s4 when it comes out. I know it would probably be cheaper to buy the 16 mg version ,then buy micro sd card.
My question is does the phone work faster from the internal memory or does it pulll info just as fast from a micro sd card?
(2). Would sandisk extreme pro be a good choice ?

just make sure you get the ultra class 10 as it has faster speeds than the lower class cards
put the things that need to pull up fast on the internal memory like apps and put everything else on the card like music and things you wont notice a difference on

Not always true. I recommend reading benchmark test on the card you want to by and its competitors. I've seen some benchmarks where a Class 6 Sandisk beat out a Kingston Class 10 in the past in "some" writing areas.

I had a nightmare with sandisk in general both in my dslr and GS2. I use Lexar now and never had one issue. Sandisk has great customer service though. Refunded all 3 of my pro cards.

If the Galaxy S4 supports the UHS sdcards (45mb or 90mb read/write) then that would be as fast as you need imho.

This is extremely true! Never trust an SD card by what the claims are on the box. I have purchased many SD cards (all brands) over the last couple of months. 6 class 10 Sandisk all 32GB from different sources (Amazon, Best Buy, Radio Shack, etc...) and none of them benchmarked in at class 10. Most were between class 4 and 8 write speeds with read speeds being a bit better. 2 PNY 32 GB class 10 cards. Both of those tested above class 10 performance but died within 2 weeks. I have not been able to find and Amazon Basics 32 GB Class 10, but the other Amazon cards I have tried have worked well. Samsung cards seem to work well as well, but I have not benchmarked any of them. It really seems to be a crapshoot if you get a good card or not. Each specific device seems to like some brands better than others. Also, there is a huge (and I mean huge) problem with counterfeit cards and misrepresented (changed) class of cards flooding all markets. So good luck and let everyone know if you find a good card.

I also would say, download and do a full write format on the card with sdformatter https://www.sdcard.org/downloads/formatter_3/ prior to use. I have gotten many 4 speed cards to record hd video on my t3i just by using that software, when a regular format won't work.

If the Galaxy S4 supports the UHS sdcards (45mb or 90mb read/write) then that would be as fast as you need imho.
