I was in the same boat , after reading through various threads , I
now have a class 2 16gb card on the way
I've got a 8gb cauz i aint store that much video's and mp3 on my phone that i need 16gb
If you use app2sd, or plan to use it, class 6 is a better choice.

Not necessarily! My 16gb Sandisk class 2 card outperforms class 6 minimums.

If it does, then why isn't it a class 6?
what is a good program to benchmark SD card speeds in our phones?

The classes they are given are the minimum they must be able to do.
If a card maker makes 10 batches of cards and they all turn out to be capable of class 6 speeds however they only have orders for 5 batches of class 6 and 5 batches of class 2, what do you think they'll do? Label half as class 6 and half as class 2.

As has been said - the class of the SD card just guarantees you a minimum speed - in fact, a minimum sequential write speed.
I get the following:
16gb Sandisk Class 2
Sequential Read : 20.050 MB/s
Sequential Write : 7.415 MB/s
8gb Transcend Class 6
Sequential Read : 19.938 MB/s
Sequential Write : 15.020 MB/s
(Tested using CrystalDiskMark 3.0 with both cards in an adaptor directly connected to the PC via USB)
Both cards well exceed the minimum 6MB/s for Class 6, with the Class 6 card coming out as twice as fast as the Class 2.
If you're using a high-res digital camera, you will notice that write speed difference as it will decrease the amount of time it takes to save a picture and thus how quickly you can take the next. However, in general use on a phone you just will not notice this, making the Sandisk Class 2 card a much better buy.

Im planning on buying a 16 gb microsd card but all i can find is cards class 2 is that enough for recording 720p and loading applications installed to the SD card ? keep in mind that i also plan un buying a optimus 2x which has 1080p recording
Which brand do you like better? sandisk? kigston? trascend?
I read that sandisk class 4 cards are REALLY good but they dont show up in their website or amazon :/ , it seems they only sell class 2 cards, and kingston offers cards class 10 and 4 , class 10 seems a little excessive
Class 4 but really class 6 is what u need class 2 will die
Sent from my GT-I9000 using XDA App
yeah minimum a class 4
class 2 is just a pain, it will make you want to throw the phone away, and explode it into a million tiny bits
class 6 is the normal speed for a fluid experience
Im using a Sandisk 32GB class 2 card, it writes at 5~7Mb/s depending if its a large file or several smaller ones and read as higher than 15Mb/s

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

Approximate usd 85.
The class designation of SD Cards ONLY represents the sustained WRITE speed to the card in MB/s. So, class 2 means it can be written to at 2MB/s, while class 10 means it can be written to at 10MB/s.
The designation has no reference whatsoever to the read speed of the card. So, basically every response stating otherwise in this thread is wrong. You should be able to get suitable sustained read speeds out of any class 2 or higher SD Card for the purposes you will be using it for. It will just take you longer to transfer the data to it in the first place. As for video recording from your phone, class should should be plenty as I'm pretty sure 720P comes in under 2MB/s.
Wow, yea. Just that i seen some online shops which class 2 32gb cost 100$
But on amazon the lexar class10 32gb is really cheap...
http://www.amazon.com/Lexar-MicroSD...610M/ref=sr_1_1?ie=UTF8&qid=1296152464&sr=8-1
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.
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.
Hey guys, I just got my sensation yesterday! YAY So happy with it so far.
But can any of you guys recommend me which micro SD card is the best for sensation? I am looking to get 32GB.
I heard it will make the apps lag if the SD card is not very compatible with the phone? Any idea guys? Please help me. Thank you.
someone here mentioned that sensation only reads/writes upto class 4...so i guess it wouldn't really matter if u get a higher class
but u may end up using the card for something else like a camera. so it doesn't hurt to get a higher class
So what is the highest class available now? What brand do you recommend? Thanks for the reply!

Complete rubbish.
The official specification for Class 10 is a read speed of 10MB/s and a write speed of 10MB/s.
The official specification for Class 4 is a read speed of 4MB/s and a write speed of 4MB/s.
(sorry if that was stating the obvious, but I don't think some people realise)
The benchmarks for my Lexar 32GB Class 10 card in my Sensation (using "SD Tool" from the Android Market) are a read speed of 21.4MB/s and a write speed of 8.3MB/s (taken from an average of 4 tests).
So the Sensation doesn't quite meet Class 10, but it's much faster than Class 4 and 6.

DHD supports class 10 cards. I personally have a 16gig class 10.
From what I have seen there's only a marginal difference between 6 and 10.
If you already have a class 6 there's no need to go for a 10.
Otherwise go for the class 10. You'll be amazed at the speed.
i wouldn't recommend buying a class 2, they may be cheap but the performance sucks
