will i be able to use a class 4 micro sd card?
http://www.amazon.com/SanDisk-micro...2?s=electronics&ie=UTF8&qid=1304280254&sr=1-2
or would anyone recommend something different?
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.

Hello,
Now that Froyo more or less came out and apps will start having Apps2SD function, it's time for a MicroSD upgrade.
What I want is on-phone performance - that running heavy 3D games on SD would perform as smoothly as if it was on internal memory. Is there a general consensus on what brand/class would suffice, and what is overkill? I have no concern over data cable transfer speed, as I'm pretty sure the phone will limit the speed much before the SD card does.
I'm looking at this Sandisk 16gb MicroSDHC Class 2 for $35 after shipping:
http://www.amazon.com/SanDisk-Flash...ref=sr_1_1?ie=UTF8&s=pc&qid=1275145563&sr=1-1
Anyone know if this would suffice?
Past threads have always went on tangents about good brand vs knock offs, how class is important vs. a marketing ploy, etc etc. Has a general consensus been reached in the xda community over what is sufficient but not overkill for onboard performance? Perhaps people who have already ran App2SD and use games and videos a lot have some input.
Thanks
I have a Top Ram 16 Gig class 6 and I think I paid about the same as you looking to pay for a class2. I also have a class2 that I have had for over a year. I used to use it in my blackberry. It still works and it is made by one of the cheap manufacturers.
Argh, I'm suffering from chronic SD corruption. So I'm in the market for a new chip. Think I'll spring for a 32gb this time. What's the latest on one that's both compatible and fast? And cheap too, that would be nice, links appreciated.
Considering that due to the amount of RAM the N1 has your main apps will be loaded already so card speed is not a significant factor, unless you use lots of different apps on a regular basis.
A faster card is beneficial mostly for the time i takes when I am loading up new music and possibly vids if you use it for that
This is the first 32gb MicroSD card I have seen "In Stock" Pretty expensive for a class 2 though.

Micro SDHC is a standard that supports up to 32gb. Of course it can handle it just fine.

bewar ebay, there a lot of folks selling fake cards. They even read as what they were sold as but then fill up mighty quick............
The class is not needed I don't think
I have a class six and have been running games on it from sd for 3 months cant tell a bit of difference. I run linpack from sd and it works fine too!

I'm running a 32gb Sandisk Class 2 in my Nexus as of last Friday. No problems (apart from a looooong time to refresh the media library after resyncing my music).
You can not get a genuine 32GB Micro SD card for US$40.
A good class 2 card (2MB/s) will offer you the same performance as any other class in your phone.
The limitation is not the speed of the card.
Buy a brand name card with the capacity you require and be done with the complexity.

I don't know too much about transfer rates but basically what you're saying is that a a brand name class 2 card will be just as good as say a class 6? I'm in the market for a new SD card as well, and the class 6 cards are much more expensive. I'm wondering if they're worth it.

No, in a phone they're not worth it at all and people who say so are either selling snake oil or are embarrassed because they've paid for one and are foolish for doing so.
The best I can do just at the moment is this:
wikipedia said:
In applications that require sustained write throughput, such as video recording, the device may not perform satisfactorily if the SD card's class rating falls below a particular speed. For example, a camcorder that is designed to record to class 6 media may suffer dropouts or corrupted video on slower media.
Click to expand...
Click to collapse
The Nexus, like probably every other phone out there, is a) not typically used for high rate sustained write activities and b) is designed to write to class 2 media to begin with.
If you have a large, highly fragmented sd card higher speeds will help. This of course is easy to avoid in the first place.
Get a higher capacity, class 2, brand name card for the same money and you're away laughing.
NB - If somebody waves a magic wand and all of a sudden the Nexus can record video at 1080p at a high enough bitrate then perhaps my advice would be invalidated... but don't hold your breath for that to happen...

Thanks for the info man! I was obviously misinformed, you just saved me a bunch of money
so just curious. now that CM 5.0.8 comes with 720p recording, would a class 2 still suffice?
I am also searching the web recently to look for a cost-effective high vol microSD. My finding is: don't 100% trust the "class" specified by mfr. I used ATTO Disk Benchmark to test two 8G microSD that I have: Transcend 8G Class 6 and Sandisk 8G Class 4.
<Transcend Class6> Write: 6-10MB/s Read: 16MB/s
<Sandisk Class 4> Write: 14MB/s Read: 20MB/s
From similar test results on the web, it seems that Sandisk uses to under-state the performance of their card. Finally I get a Sandisk 16G Class 2 for my N1, and here is the test result with the same setting:
<Sandisk 16G Class2> Write: 7MB/s Read: 20MB/s
Although Sandisk only specifies it as class 2, it actually performs like a class 6.
I suspect the importance of the speed of the SD card too, coz I think the write speed into ROM, should be way slower than 6-7MB/s (correct me if I am wrong ^_^)... If the speed of v2.1 w/o app2sd is acceptable to you, then v2.2 with 6-7M write speed card should be logically fine with you.

huh that's interesting. i just might pick that up from amazon then..
I Dont think fragmentation makes any difference to write speed, these are not mechanical devices like hard disks.
Also defragging is pointless and shortens the life of the card by increasing the number of writes.
Hello,
I have a 8go storage for now but I'm getting close to be out of space (I have like 700mo left).
I would like to buy a 16go sd card but I'm not sure which one...
I have a nexus one rooted (with A2SD) so I don't really know what I should or shouldn't take. (because 20$ of difference between two "same" card is suspicious )
Could you help me ?
Best regards,

Sandisk is a reputable manufacturer, Kingston is another, but make sure you also use a reputable retailer so that you don't end up with a knock-off.
The Nexus One can't utilise speeds above Class 2 so unless you are planning on using the card in a dedicated card-reader a lot, or are thinking of future use, i wouldn't worry about spending premium amounts on faster cards.
min. class 4 is a must but you could look for class 6

This is true. My PC transfer speed is insanely slow. Took over 6 hours to transfer 8GB of data (was re-partitioning and did not have my microsd adapter)
A 16GB class 4 chip should be about $30, unless you jump on a special deal.

Obviously, but transferring files is the only reason why you would need a faster card. With the N1 seemingly capped at low speeds..yadda,yadda,yadda...
No it's not.
Recording in HD will require a decent speed, running data/dalvik-cache off SD-EXT will require a decent speed (things are noticeably slower on my C4 when I do that).
I've used a Class 2, Class 4 and Class 6 card on my N1 without any noticeable difference. I've put a clock on metrics like app launch times without any difference in the results.
People who spend extra $$ on faster cards convince themselves that they notice a difference to justify their spend. I wanted my Class 6 to make an improvement in daily usage but it didn't. I have to put it in a card reader so that i get any benefit from it, and that's only justified for transferring large amounts of data as you have to consider the time needed to remove/replace the card.
so personal expierences = fact now?
because I notice a major difference between my class 2 and class 6 in my N1
so that makes a new fact now
Can we have some facts on this issue?
For example, is it faster to take pictures if you have a faster class speed?
Is it faster in executing tasks?
etc.
Anyone have any results?
I'm thinking of getting a class 10 microsd card for record 720p video.

I'm using a Patriot 16GB Class 10. Overkill? Maybe - depends on who you ask. But if you're putting the system cache on the card and recording HD video, it certainly doesn't hurt.

since i cant post link:
ADATA Micro SD 32GB SDHC class 4
Speed (read) : 10~14 (MB/s)**
Speed (write) : 2~5 (MB/s)**
Speed Class : Class 4
its cheap , it worth a try

I read that some cards were more accurate with their transfer claims than others. Can't remember the brand of card but one was recommended as being closer to the spec than the others. Also remember reading something somewhere that suggested a Class 10 card wasn't desirable and not necessarily faster because of how it worked, and that a Class 6 would do better for read/write and battery life. Your thoughts?
not really sure if I would spend the extra cash on a class 10 16b over a slower card for use in a phone. class 10 are superior for video, especially hd, like with a digital camera.
now, if the price is not much more I would go for class 10 but that is because I have found that once you replace your device, you may use your old card in a new device that now needs a faster card.
from sd association:
Class 2 : H.264 video recording, MPEG-4, MPEG-2 video recording
Class 4: MEPG-2 (HDTV) video recording, DSC consecutive shooting
Class 6: Mega-pixel DSC consecutive shooting, professional video camera
Class 10: Full HD video recording, HD still consecutive shooting
I do not agree with all of those uses but class 6 should be fine for your phone, even class 4 may be. plenty of info on the web if you want to check it out more. Again, if price is not an issue or the price difference is minimal go for a faster card. also, do not buy from ebay as there are a ton of fake cards on the site.

this was a good deal. just expired, but a similar one may surface :0

The problem with these ratings is that they're intended for use in recording devices, and don't discuss suitability for use in a device such as a PDA where you'll be running programs off of the card.
The information I've seen on the 'net is sketchy, which is why I'm asking here.
Two things to answer:
1) What class is suitable for running programs from the card?
2) What brand/model of card comes closest to advertised rating?

It really depends on a number of things, how much information is being used at one time for a certain app, since all apps are different. So you can't really say, but if you want to make sure then go with a class 10. A class 6 should be fine for most of the apps on android though.
As for which brand of card comes closest to advertised. Each Sd card is different just like every processor is different. You can get a Kingston 8gig class 4 that only transfers at 3mb/s or one that transfers at 4.2 mb/s. Generally a good standard to go by is (cheap/fast/reliable) you can only pick two.
The only way you are going to know the actual speed of the card is to bench test it. For my money though I would probably go with kingston or pny.
The stock card is a Sandisk class 4 and based on that I would say that a class 4 would be fine, but a higher class shouldn't hurt.
capman231
My stock card is a samsung class 2..... And it is forever unexpectedly unmounting.......
Just ordered a Kingston 16gig class 4 for $30 shipped on amazon.
i just bought a 2GB PNY from BestBuy for $7. Couldn't be happier!
It really depends on what you plan on doing with the card/phone. If you are just going to use it for apps and smaller data files the class 4 or 6 will be fine. For me I use the phone for work and media. I stream music via bluetooth in my car and wired to my boat while also storing larger pdfs for work, like my companies catalog. Not to mention if I ever want to take any 720p vids.
I have a 16gb class 6 that has outlived its usefulness as Android stores more data on it than my previous windows phone, so I'm deleting more & more music to make room. I just purchased a Wintec 32gb class 10. I will test the speed with the card in the phone mounted to my computer via usb and if the speeds aren't there I have no problem putting it in a card reader to transfer what I need. I can easily throw 18gb of 192bit mp3s on it, more if I keep some of the songs as flac. I feel the time saved transferring justifies the $76 price.
If you go with a larger card just remember to unmount it before disconnecting and you'll save yourself a lot of headaches.
I want a 16 gb card, but which model is the fastest ? i know a class 4 can outperform a class 6 card and so on , a class 4 pny card? a class 4 kingston? or a class 6 trascend?
You have it backwards a class six is supposed to out perform a class four and a class ten is supposed to out perform a class six.

apparently the brands lie when they say what type of cards they're selling, think of it like a 5 mp camera outperforming an 8 mp camera i CAN happen

I'm not saying it can't, I have a 8 mega pixel sony cybershot that has a carl ziess lens and its pictures are way clearer then my 14 mega pixel cannon point and shoot, but like I said before you have to bench test it before you know its true potential. One kingston 16gig class 10 is not going to preform the same as another kingston 16gig class 10. It is possible to have a class 6 out perform a class 10, but in general the higher the class the faster the transfer rates.

Personally I am not sure I tend to stick with pny and kingston. What I would recommend is looking on amazon or another place that has reviews usually a good reviewer will post a bench test with transfer rates.
I have been using this Adata 16gb cl6 for over a year and a half. The only problems I've had with it are occasional corrupting, but that is completely attributable to my lack of unmounting the card before disconnect. I haven't had a single issue since I started unmounting.
I would also recommend their cl10 card which can be found here.
I wish Adata made a 32gb version. I will report my results on the Wintec once I receive it.
I used a class 4 16gb SanDisk for a long time and it always was fine. I am a sucker for room though, and bought a Lexar 32GB Class 10 and I really couldnt be happier.
I just researched this the other day and can't find the link for the life of me..
Basically from what I read the class 2 and class 4 cards have a faster read than the class 6 and 10's. It has to do with some initializing the 6 and 10's do which is an extra step compared to the 2 and 4's.
For a digital camera the class 6's and 10's are better but for phones a class 4 is ideal. If I can find that darn link i'll post it.
I have an 8gb class 6 transend in my N1 atm and when I get my Inspire in tomorrow i'm going to test the class 4 against the class 6 to see which one has a higher read speed.
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?
thanks

I would like to know people's opinion or facts on this as well. I'm currently looking for a 32GB card to purchase and this information would really help out.

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).

thanks. appreciate the info.
on amazon there is a Samsung class 10 16gb for $20 right now. 16gb would be fine right now, but I dont want to be running out of room in 6 months as I like to record video which takes up a ton of room. so thats why im looking for a 32gb (even though i think that will be way more then i actually need).
on amazon i actually dont see any class 6 32gb cards; except for 1 knockoff brand. so it seems like most 32gb cards are either class 2, 4, or 10. i want to go above a class 4, but class 10 are expensive...
thanks
A-Data Class 10 microSD 32GB
bought that one couple of months ago, verry happy with it. was the cheapes one to get back then, about 55€ / 75$
getting 10,5MB/s writing and about 12MB/s reading on USB port. just a little slower than my flash stick...
didnt notice any change while recording videos, but i dont unse the camera that often.

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.

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.

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.
