I have the stock 8G card in my Inspire, but want a 16G card so I can move apps (and other data) over. Is there any real difference from one 'class' of card to the other? what would you guys recommend?

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.

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.

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.

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.

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...

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

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.
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,
rXp>!<
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.
So far I've used Kingmax 16GB Class 10 with no problem.
I just bought a Sandisk 32gb MicroSDHC Class 2, hope it will work fine with everything, need a lot of space for music
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.

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

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!

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 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.

Are you using the class 10 card in your G2x? Are you getting legit class 10 speeds?
It looks like everybody in this thread is happy with class 4... anybody getting appropriate performance on higher class cards in their G2x?

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.
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.
My 8GB Memory Card in my Sensation XE if almost full now, and i plan to upgrade to a 16 GB MMC. I know that Class 4,6 and 10 have Read/Write speed or 4/6/10 MB/s respectively on the computer.
I want to know, how does these different classes affect when running in a phone except the obvious copying files thing.
Thanx in advance.
I believe as you said that the same holds true for the device. It has to do with the speed. I also just upgraded myself to a 32 . This is the first time I've used a 32. But I only have a class 4 ( same class that came with the device) as I really couldn't afford the higher class at this point. I've had no problems so far and it seems to be working well. I would like in the future to obtain a higher class and see the difference for myself.as I also wonder what kind of differences it will make on our device. Best wishes to you!

no budget stated so i'd say go for sandisk 64gb sdxc.
Have one right in my sensation for a few weeks already
back in my htc magic days, i was always told class 4 = too slow, class 6 = perfect, class 10 = too fast (yea, too fast)
of course android came a long way since then but i got myself a class 6 anyway
Well, I don't know if it is the same for micro sd's but in my GoPro I have a class 10 32gb SD card previously having a class 4. I would say that since I have upgraded to a class 10 my copying speeds to and from my camera have halved and the footage that I get seems to be of a higher quality. So I would say get the highest class you can afford. Hope that helped!
The difference in speed is VERY noticeable when taking pictures on a class 6 card compared to a class 4 card. There's very little delay when the picture is saved.
Class 6 was well worth the money in my opinion.
Edit: oh, and also, there's no lag when playing high bitrate video.

Okay, Thank you everyone
I think i am gonna go with "Transcend Memory Card MicroSDHC 16GB Class 10". I'm gonna order it and will post what difference i notice ! :highfive:
your posts really helped
i read in the official sd site that in order to achieve optimal performance you must match the speed class of the card with the one of the card reader. for instance, if the sensation's card reader is rated class 4 faster cards will provide no benefit -- and a few drawbacks, too. the problem is getting to know what class the sensation's card reader is mounting
Class 10 is usually optimised for digital photography/video where small numbers of very large files are written. Smartphones read and write hundreds or thousands of small files and hence might preform better, as the card fills up with a class 6.
Having said that I doubt anyone would be able to really notice the difference in real life...
Also, go for at least the 32gb card, price difference is usually tiny and you'll take a while to fill the larger card.

bought 2x 64gb U1(c10) sdxc and filled with dramas/movies in 1night after I bought these, so capacity filling really depends on people
Good call with the transcend card. As far as I know they are the only ones with ecc on board, and I have never had one fail.

Yeah, your'e right. My friend who is a photographer by profession told me the same thing.
I don't know how its where you are but where i am, i see that Transcend 16GB class 10 is Rs.885 / $16 / GBP 10 and the 32 GB Transcend Class 4 is Rs.1400 /GBP 16/ $ 25 so it kinda gets expensive.
There is one from a brand called 'Strontium'...the class 10 is cheaper than Transcend Class 4......32 gigs. But have you heard the name before ? i havn't...

well, if there is no means to figure the reader's speed out, i would not waste money on a class 10 and play it safe with a class 6 or 4. at the end of the day i am no speed / stats / benchmark freak, and prefer to solve actual problems rather than having the fastest stuff available. i'd take the most stressful task in real life (namely: playing 1080p video without hiccups) and then opt for the cheapest card that handles it without a flaw
I have a Sandisk Extreme Pro 16GB card on my sensation. Really have much greater speeds when transferring data between PC and card. My nandroid backups used to take about 300 seconds with class 4 card, which have come down to about 150-160 seconds with new one. Also I'm using hard swap, which benefits using a higher speed memory

Btw...what is hard swap ?
If you root your phone then go for class 10.
But if you stay on stock rom there is no need for fastrr then class 6.
I do not know the price difference (where you are buying) but I think for everyday usage you will not notice the difference.
