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.

you sure that is a class 10 micro SD 32GB? (i think it's a normal size SD)
if so, i'm soooooooo buying one
please post link, i want to buy
Talking about the classes.. ya think the GalaxyS can really max out the speed? I doubt so..
Sandisk 32GB SD card is a class10? What is the max read/write transfer rate can anyone can confirm? Please

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
will i be able to use a class 4 micro sd card?

Any class will work. The higher the better. It will be faster. I have a 16gb kingston class 4 card and it works great.

"The higher the better"-that's a false statement, but if you want to get the best oud of the MicroSD, go for class 4 or class 6. Am currently using a class 4 8gb.

the fact it may not support as high a speed class as you can find.
for example my N1 would support a more expensive class 10 card but not at those speeds as the N1 was limited to i believe 4? so a class 4 is all you would need
Im not sure what our G2X supports but a class 6-8 should be fine

There are also quite a few tests out there that show many class 10s transferring slower than some 6s. I shopped around for a while on newegg, not many good things coming out of the 10s on that site. 16gb Adata 6 is what i settled for. If I end up needing something larger in the future, and I have the money, I probably would go with the 32gb Lexar class 10.
what's the cheapest anyone bought a 16gb from a reputable site/seller online? i'm eying the patriot 16gb on amazon for $25. 3rd party seller can be fake.
I have a 16gb Class 10. The statement higher the better is true. A class 10 vs a class 6 thats a difference in speed of 4mb.

Theoretically, that is the case. 10s are suppose to be faster. But that's the manufacturer's marketing that says such. In real world testing, they are not getting much faster speeds (or are actually slower) than some 4s and 6s.
Buyer beware.. do the research yourself and you'll find what I found. I wanted to get the best card for this phone.. and after much reading, I stayed away from the 10s.. Do some browsing on newegg and read the reviews on all their 10s.. it's not pretty.
I'm not sure about other SD cards but i have a class 6 on my N1 that while it worked it wasn't great when running some apps from it or when view lots of pix in the gallery.
with the G2X that isn't as much an issue, but can anyone recommend a fast 16gb card? hopefully fast enough to run apps from if i need it later on
I found a couple class 10s that had great reviews from other cellphone users and I chose one of those. (It's in the mail now.) Are you guys saying that our phone is limited to sub-10 speeds or that the cards themselves are not as good at higher classes? I thought the class rating was determined by the card's speed... if so, wouldn't a card that is slower than a class 6 be rated below 6 by definition?
The lower classes are considerably cheaper so if I bought something off, I need to know now!

I dont know for certain but I doubt the G2X supports class 10 speeds.
as far as cards being slower than the advertised rating, its just typical marketing. just like HP ratings, GHz clock speeds, Megapixels, Amps,watts, ect ect
The class speeds stamped on these cards are notoriously unreliable. The 16GB Class 2 card that came with my HD2 consistently beats my brand new Class 6 card on every benchmark I run. I recommend buying from a retailer with a decent return policy and benchmarking your new card to make sure your getting the speed you've paid for.
The other issue is at what speed the G2X's SD interface maxes out...and I've seen no data on that...
Do any of you guys have benchmark data on your SD cards in your G2x for whatever class card you have?
Guys heres how it works:
HAve you ever tried to put 8gb's of memory into a computer that only supports four?
Or a faster memory into a computer that only supports the later?
same thing if your phone doesnt support the class/speed/size its going to run like SHEEEot/slow/not at all!!
I have the class 4 16gb card and it works great. why spend money on something you dont need?

I did on the Adata 16gb class 6.. It was reading at around 18 and writing at over 10. That was putting it up there w/ class 10 specs..
Manufacturers suggest using the SDFormatter V3 to format the card instead of using other utilities in the phone or windows.

I don't think anyone knows for certain what the phone is capable of. If you find that out, great.. please let us know.
What I'm trying to relay is that the speeds mentioned on class 10s are not what they are all cracked up to be. Sure, higher is better.. but it's only better if it actually achieves a higher speed. Also, it must be a higher speed that can justify the price difference. Beating a class4 by a cpl mb/s but double the costs was not worth it. I spent a few days doing research on this.. studying many different test results, etc. I could go back through and find all the data for ya.. but I don't have time. My final result was that the class 10s were not worth it.. they had a higher fail rate than the 4s and 6s.. they were less recommended/had lower reviews than the 4s and 6s.. in some cases, they performed slower or at par w/ a 4 or 6, and they were dbl the price. There was absolutely nothing that said it was a good route to go. Nothing outside of the marketing.. "Class 10!!!"
In some cases, depending upon manufacturer, you can find a class 4/6 that will outperform some class 10s. I also see a much lower customer satisfaction, malfunctioning cards, returns, etc. when it comes to the class 10s.. much more than any other class.
Hi all,
What is the maximum capacity Micro SD card size on the TF and also, what Class type do I need?
Thanks in advance
32 gb has always been the limit.
OK thanks, but what 'class' type? I see class 4 and 10 advertised?
well the class is the write speed of the card. The higher the number the faster the speed with 10 being the fastest. I use a class 4 that i had from my thunderbolt and that works just fine
Dont think it matters what class, it's just the write speed of the sd card.
And what all can you use this SD memory for?
Class just specifies the maximum write speed, but with day to day use in the transformer (other than transferring the initial media) it's the read speed that's the most important. You''ll be storing and opening your media from it (music, pictures, videos and PDFs or other e-reader formats most often). Usually a card with fast write will have fast read speeds as well but there can be some anomalies with certain cards so it's not always so clear cut. In my experience anything above a class 4 seems to work just fine. If you're working with a lot of larger video files though probably class 6 or above would be better (and as it's also a little more future-proofed). I would always prefer to go with a named brand class 4 or 6 rather than a non branded class 10 though.

Even that isn't the whole story because it's incomplete - the class of the card minimum sustained write speed of the card under optimal conditions (i.e. a brand new and completely unfragmented card). I'm sure someone else can improve on that definition further!
As to what speed of card you need, from sdcard.org:
Class 2 : H.264 video recording, MPEG-4, MPEG-2 video recording
Class 4: MEPG-2 (HDTV) video recording, digital still camera (DSC) consecutive photo shooting
Class 6: Mega-pixel DSC consecutive photo shooting, professional video camera
Class 10: Full HD video recording, HD still picture consecutive shooting
Planning on doing any of these with your TF?
I've been using good quality Sandisk Class 2 cards in all my Android devices since the original T-Mobile G1, and *never* had an issue with them. Plus when testing, I usually get a write speed of around 7.5MB/s.
Regards,
Dave
I use a class 4 16gb and its fine. No problems. I think the faster classes are over rated. I typically try to find a class 4 or 6. Both work great. Don't waste your money.
You can get a 16gb for about $25 and a 32gb for around $40

FAssuming Asus implemented SD 2.0 standard, a 32 GB maximum storage capacity is your limit for any SDHC memory card. You can read more about it here: link.
As for which class you buy, it depends on what you're using the memory card for. Foxmeister answered with a class rating list. Do note that the higher the class rating, the more expensive the memory card is. Like wise with storage capacity. I recently bought my PNY 32 GB microSDHC class 10 memory card from buy.com for about $57. Caveat emptor with fake ones on eBay, especially ones shipping from China.

yep, picked up one of those "fakes on eBay". That really stunk.
I know class 10 is faster then class 4 or 6, but just wondering if the Sensation takes advantage of a faster card? For example, will recording in 1080p (on the sensation) be better if i get a class 10, versus a class 4 or 6?

thats why im trying to figure it out. there is a hugh price difference between a class 4 and class 10 32gb.... Im just trying to figure out if our phone actually uses the extra speed of a class 6 or 10... Also, if recording video on 1080p will be better if i go for a class 6 or 10 over a class 4 (which I think came with the phone)..?

I can say confidently that our phones will perform better using a class 6 over a class 4, but the question of "will our phone use all the speed a class 10 offers?", I can't answer as confident. But I would think that it should not have a problem using a class 10 to its full potential. What class 10 micro are you looking at?
Using Samsung as an example:
http://www.samsung.com/us/computer/memory-storage/MB-MPAGA/US
This is a $55 microSD (it was half off last week on Amazon[Cyber Week]), but the read/write is 24MB/21MB and a class 4 only gets 15MB/7MB(http://www.samsung.com/us/computer/memory-storage/MB-SS4GA/US [this is a SD but of a class 4]).
If anything I would get the class 10 just to be future-proof and avoid having multiple microSD's around the house. I'm using Samsung as a reference and I do not have experience with their memory cards so I am not trying to sell Samsung. I did buy a 16GB class 10 microSD from Sammy via Amazon for Cyber Week (only $30), its being shipped right now, if you want an update I will make another post (class 4 v. class10).

on amazon there is a Samsung class 10 16gb for $20 right now. 16gb would be fine right now, but I dont want to be running out of room in 6 months as I like to record video which takes up a ton of room. so thats why im looking for a 32gb (even though i think that will be way more then i actually need).
on amazon i actually dont see any class 6 32gb cards; except for 1 knockoff brand. so it seems like most 32gb cards are either class 2, 4, or 10. i want to go above a class 4, but class 10 are expensive...

If you are in the U.S. Fry's has the 32GB Class 10 for $20 off
http://www.frys.com/product/6786695?psrid=14599570
That probably expensive also, but I could not find a 32GB Class 6 either.
I'm using a class 10 16gb card in my sensation
seems fine, only thing that is fast is displaying pics in gallery
wish I got a class 6 and saved the money, I haven't tried 1080p video....
just tried a 10sec video. Wrote instantly on card and playback instantly too
10sec vid is 13.96mb
so I think a class 6 card can write at 6mb/s where as class 10 writes at 10mb/s
class 6 is fine!
I was in the same position as you are right now.
I did a little bit of reading and decided to buy a good (SanDisk) Class 4 over a cheap (alot of offers from brands I never heard of) Class 10/6.
My reasons:
1. Good card with lower speed = less chance of corruption
2. The read-speeds are ~ identical, since I don´t really use 1080p I don´t need high write-speeds (allthough 1080p records without a problem)
3. Random acces speed on lower class cards is higher, since the high write speed is a trade off between random access speed and write speed.
After reading about all that the decision was easy

now im really confused...
a good compromise would be a class 6, but obviously i cant find any brand name class 6 32gb.
I dont really know much about random access speed vs write speed....can you enlighten me? are you saying that class 4 is faster in some situations then a class 10?

The random access speed is splitted in write and read. It is the speed whith which a random bit can be written/read.
It is the value that determines the performance of an app using SD-Card for data.
So in daily use, there shouldn´t be much difference between class4/6/10. If you want to use your SD for daily putting tons of different stuff on it, you may be better of with a class 10. If you put a lot of Music on it and leave it there, a class 4 is the way to go.
(Anyone correct me, if I´m wrong here, but that is what my research brought up)
I'm the same as Sibbi and am using a good quality (SanDisk, same again) class 4 32GB uSD card.
And I have no problems with it at all, it keeps up with video recording (at full HD) and plays back perfectly.
I suppose the additional speed of a class 10 might make the difference if you were copying GBs of data across the USB cable when loading up the card with music or something (in which case just be patient!) but for normal use I really don't have any issues.
The sensation is a good quality expensive device, so my advice would be to use good quality memory in it for reliability, rather than take the risk lowering the reliability of the handset with lower quality accessories.
Can asus transformer really take advantage of a Class 10 MicroSD card? Or should i just buy a class 4?
The difference in speed is noticeable but it depends on the price difference...
I think so. I have a samsung 32 Giga class 10 and the speed is appreciable.
You can find on amazone for around 35 Euros this type of micro sd
The class Does make a difference, I have a 32 class 8 that works very noticeably better than my class 2 4gb. If you do HD video or heavy file transfer jump for the higher class. Class 6+ should be plenty fast enough for the average user, I'd avoid less than 4 though. Just my thoughts.
from what Ive read on this forum though class 10 write speeds are faster in some devices the way android devices read is different and you actually want something like a class 4. thread is in one of the general forums, title is something about looking for fast 32GB SD cards. That being said I picked up 2 class 4 32GB micro SD cards from newegg when i got this transformer. the second went to my G2X replacing a 16gb class 10 card and i dont notice any loss of speed.
Yea. this is also depending on devices ability in handling class 6 to class 10..
Some older device can only handle 32GB with class 6 max but would give all sort of problems for the same 32GB with class 8 or class 10.
But this TF101 would have no problem for all type of classes available since it's running dual core by default.. So a class 10 would be the best choice to fully utilize TF101 true power and speed..

I have never heard of an older device having issues with faster card simply because of the class speed, they just wont read it at the speed the card is capable of. My G1 and N1 both handled class 10 cards without issue even though the phones could not read that fast.
Ive also never heard or see how a dual core would make any noticeable difference on read and write speeds.
BTW I think if my memory is correct the difference in class speeds was read/write. if you plan to transfer lots from device to device or constantly write to the card like a digital camera you would want class 10. if you have an android that will mostly be reading a class 4 or so was recommended.
EDIT: found one of the links.

If you're using this for a phone, you may not want a class 10. A class 2 or 4 Sandisk may be better for you. Depends what you're using it for.
Class 10 gives fast sequential speeds, but it usually sacrifices random read, write and access speeds. I could go into the reason why this happens, but I've posted several times about that, so you can check my previous posts for that.
Class 10 is good for digital cameras or other things where sequential speed is important and random speeds aren't important. If you're using the card to run apps off of, or system files for Android, or any OS actually, or using it for WP7, or anything that will need sequential speeds and fast access times, class 10s are slower than good quality class 2 or 4 cards like Sandisk.
Higher class DOES NOT mean better or faster for everything. Class only refers to sequential write speed. Different types of cards are better and faster for different tasks. Class 10s will many times slow down or cause lag in phones, depending on how the phone uses it. Sandisk class 2 and 4 cards I have found to be the best all around cards for phones.

Can asus transformer really take advantage of a Class 10 MicroSD card? Or should i just buy a class 4?

Depending on the usage since by default /sdcard is mapped into its internal storage, uSD (Removable/MicroSD) is hardly used by the apps, of course, media file, backup (Nandroid or Titanium) will be faster with faster uSD.
Here is an extremely informational post about class speeds and what they really mean. I have a 32gb c10 and love it but it would behoove you to check out the Small Block Write Speeds in this post to see the real differences of read/write speeds.
