I created videos showing the dramatic difference (before vs. after) but then realized this site does not allow me to upload videos (and I am too lazy to set up a utube account).
The 16GB Micro SDHC card that comes with the T-Mobile HTC HD2 is only Class 2 and is a very SLOOOOOWWW card (also class 2 cards are CHEAP, that is why it is INCLUDED FREE). If you watch the Transformer movies installed on that card you will discover there are a few times during the movies where the screen momentarily freezes. Also if you have alot of songs on the card, when you scroll over to the media player you will see it takes forever for the media player tab (about 45 seconds) to display anything. Even a game that comes with the unit repeatedly freezes and is not playable because of the speed of the card - under games, try the game called "Ferrari GT Evolution". It is a great game but it is unplayable on that card.
I purchased a 16GB Class 6 Micro SDHC Card and it came today. I copied everything from the old card to the new card. WOW, WHAT A DIFFERENCE! It is about $60 but is makes a VERY big difference in performance for everything mentioned above. For instance, the Ferrari game mentioned above does not freeze at all (and loads much faster) and also when I scroll over to the media play tab the delay before that tab becomes useable is only about 3 seconds.
If you want a SAFE great way to really improve the performance of your unit, replace the old crappy Class 2 Micro SDHC card with a Class 6 version. WOW.
(BTW, my main reason for getting this card was also that it took too long to take a photo and then to be able to take another one immediately afterwards. Now that is MUCH faster as well. A workaround would be to not use the card for picture storage but I prefer to put them on the card.)
I have been using a 4GB class 6 card I had laying around and I have seen a difference as well. I copied all the data from the 16GB card to my computer then copied it to the 4GB card to start out with. I saw a big improvement in the momentary freezes that occur when navigating the UI, music indexing and video playback. After using that card for a couple weeks I copied everything back to the 16GB card after formatting it and popped it back in to see if it was a placebo effect. Things were noticeably different, it just felt more sluggish at times. The Class 2 card isn't bad and it isn't the whole problem but getting a better card does change things a bit.
I did pick up a couple 8GB class 6 Sandisk cards for about $10 not to long ago for my camera. The 16GB and 32GB cards aren't as economical yet. The improvement is worth $10-$20 dollars to me but not $60.
how can i tell if my other card is a class 4 or not

It'll be printed right on the front of the card...a little number inside of a circle. If you dont see one there, odds are it's a class-2
Panasonic makes a Class 10...that's what I use lolol...

Class 6 vs 2 Photo... (Micro SDHC Card)
There is no such thing as a Class 10
Look at the photo (CLICK ON THE PHOTO TO ENLARGE IT AND SEE THE DIFFERENCE) FOR THE Speed Class Designation. I guess the standard spec does not say which way is right-side up for printed labels!
Class 6 is the highest speed currently. There are 32GB cards out there (which the unit can support) but they are VERY expensive. The Class 6 card I bought was somehyting like $60 with the shipping from Newegg.com.
Also notice that it is such a damned nightmare to be able to read these ever so tinier labels on everything out there! (Or maybe it's also because of my age.)
It is true, also, that those without the class specification are much older - and slower, I guess they should all be lumped in presumably with class 2

Just merely stating the fact.
$100...Hope they become cheaper!
thanks for this thread... i totally didn't realize there were speed diffs on microSD cards.
so a few questions then:
1. the new 32GB sandisk microSD is only class 2... i assume no other manufactures are out yet, especially with a class 6 or 10. this is the very end of the SDHC standard. the next upgrade will be all SDXCs.
2. will a class10 be better than a class 6? i always thought that there are spec. limitations to SD card readers itself. does anyone know what the max limit of the HD2 SD card reader is? class 6 or 10? because if it's class 6, then buying a class 10 would be useless.
i remember that older SD card readers can't read the SDHCs.

1. I haven't seen any class 6 32gig cards but there will be some eventually.
2. Technically class 10 is faster than class 6 but unless you run everything off your sdcard and have a ton of music/video I doubt it would be worth it. If you were going to be using a 32gig card then a class 10 would probably be worth it, though I don't know if the HD2 supports that speed.

Thanks for the "usual" lolol...
To be honest I've got the class 10 Panasonic, and a class 6 Kingston, (both 16gb [32gb models are ridiculously expensive]) and when you run them side-by-side in a phone, there really isn't a difference in everyday use that I can tell. Class 6 is plenty fast for a phone. But there's always people like me in the world who aren't afraid to fork over the extra money to see if the latest tech will get me a little extra speed.
For those on the ropes as to what to get: if your just listening to music, Class 2 is good; for video, class 4 is good; if your non-stop music and video all day everyday work and play, and have some extra cash Class 6 rocks.
For all of you nut jobs like me who care about the extra microseconds of speed, lolololol, and have the money to spend...get the Class 10...
~Jasecloud4
the first thing i did for my hd2 was upgrade to a class 6 from previous experience with rooted android handsets (where upgrade to class 6 is always recommended
would a class 10 or a class 6 improve battery life?
Thanks for the thread and the informative posts, I guess I will make sure to get at least a class 6 for my media heavy device.
Also, if I were to buy one, which companies are reliable? Or are they all pretty much the same? I've only heard of SanDisk and Kingston because I've met the co owner of Kingston and he gave me some free stuff before.

I would just stick with sandisk or kingston anyway, they're both as reliable as any, and usually priced right along the lesser-known maufacturers.
So for anyone who has used both a class 6 and class 10 card IN THE HD2, is there a speed difference? I have a paypal coupon code that is good for 25% off, and am eyeing some of the class 10 kingston cards on ebay which would come out to about $74 with this coupon code. Not very much more than a class 6, course i could just use the coupon code for a class 6 off ebay too. I would like to go the 32gb route, but seems everything 32gb is class 2 =(
I am thinking about purchasing a 32Gb microSD for use with my galaxy S.
My concern is that, is this too large? Are there any bad side effect like it being too slow to display picture/start up scann/run applications?
Which brand? That's probably more important for the speed than class (a class 2 Sandisk is often as fast or faster than a class 6 from a lesser brand).
The capacity of the card shouldn't affect the speed during most situations. However the phone does scan for media each time it is turned on or after disconnecting from USB connection (Kies or mass storage), the amount of time this takes depends on:
-the amount of media stored on the card and
-(probably) the read speed of the card.
Note that class rating is minimum write speed - so it's not a great indicator of real-life performance.
Also note that some too-cheap-to-be-true cards are actually smaller capacity cards that report larger capacities to fool the customer.
BTW where are you getting the card from (I want one as well ).
Hi flamingpitofhell,
I am looking at Sandisk as well and most likely get it from their online store. I am trying to find more information whether it is worth the trouble.
I don't think Sandisk sell class 6 cards (yet). Buying from their online store's also more expensive than online retailers (I can get one in Australia for AUD155, which is ~USD137, cf their RRP of USD200).
thanks for the pointer. will look around for local stores here in Thailand.
Which city in Australia are you in? I studied in Perth more than a decaded back.
I'm in glorious Melbourne mate, haven't been to Perth yet
the only LEGIT 32GB Sandisk available right now in the market is only Class 2
if you read anything else, it is FAKE, specially from eBay
wait until the other microSD manufactures start pushing out 32GB on class 4 or class 6 before buying.
i'm using 2x 16GB Class 6 until the 32GB class 6 becomes available.
I'm using Class 2 32GB card in mine, its fine.
Its slower when you're transferring to the card from your PC, but for most people thats only particularly problematic the first time (loading music collection), after that you'll not really notice a difference in the phone (the read speeds are basically the same, and the phone can neither read nor write to the card faster than a Class 2 card can cope with). You can see it in the benchmarks taken post-mimocans fix - Class 2 cards are no slower than any other Class within the phone.
Grab one now and be happy.

Where did you get yours from and how much for. I`m interested in getting one myself.

my local stores already carry the real Sandisk 32GB class 2
too slow for my taste, i like to run Apps from the SD card, also use it as a SWAP partidion to prevent the LAG problem people complains about, it's a very easy fix

i wonder what would be better a 16gb class 6 or 32gb class 2...
is it worth sacrifising double of the memory for the speed?

it depends what you are trying to do
if it's just to listen to mp3, then Class 2 is fine
if you want to run games, software, watch movies, use it for SWAP drive to have no lag, then minimum a Class 6
Class ratings don't really seem to have too much of an effect on real world performance: http://forums.whirlpool.net.au/forum-replies.cfm?t=1468705. Just discount the last result from the SGS (it's most likely mistaken for the internal SD).
i rather trust my experience coming from PalmOS + WinMb where real life situations using a class 4 or slower cards, made a huge word of difference when launching applications from SD and watching movies from SD
funny enough the numbers reported on that topic shows SGS i9000 to have the fastest speed even using the same card that got lower speed on the other phones.
which seems to point out it's directly proportional to the CPU speed, and the multitasking software running in the back end.
however as you see on those test itself, there are speed differences between class 2, class 4 and class 6
the same class # can not be compared to another class # of a different size,
if you imagine a hard drive, the bigger the hard drive the more layers/disk area it has to read, the same is true even for static SD cards.
however as pointed on those test Transcend usually has the fastest SD cards in the market, that's why i always buy that brand for performance, using a 16GB Transcend myself, waiting for the 32 GB class 6+ to come out
Adata has 2 lines, the performance line, and the standard line
if you want speed get the performance SD cards
Kingston and Sandisk are mostly standard speed, they don't release much performance level SD cards anymore, but they do have lots of those on USB sticks.
I tried my Brothers Sandisk Class 2 32GB and it worked perfectly.
Granted it's not as fast as my Sandisk Mobile Ultra Class 4 but that card flies anyway.
Certainly for recording your large movie files taken with the camera it's no different in speed than using the built in SDCard on the phone.
I have no problems watching 720P video on my phone. I have no problems launching applications either.
So much misinformation...
of course there is no problem, the issue here is getting the top performance, any SD card will work just fine.
it's just a matter of how fast/slow are you able to torelate
The only time you will notice any difference in speed is when transferring data to and from the card.
However, when you have double the space of other cards to consider speed should not be a deciding factor.
I'm already looking to get the Sandisk Class 2 32GB card. It will store all of my work files normally kept on my Laptop.
My Sandisk Class 4 Mobile Ultra 16GB will be my spare ~ should the larger card fail...
Thanks for the information s everyone.

I have the 32GB sandisk card and works perfect. I have a 720p mkv file and my music on there. Playback was superb for the video with no noticeable lag. Mind you the card isn't anywhere near full yet. From my limited knowledge of sd cards, they put data on the fastest part first so the fuller it gets the slower the card is likely to get..
My plan is to put movies and songs on the 32GB file and reserve the internal 13GB for capturing video and taking pictures on the phone.
will the 32gb mirco sd class 2 be fast enough to run apps off the sd card without problems?? or should i sacrifice size with speed and get a 16gb class 4 or 6?
yes its plenty for this handset. many many many people already have theses cards in the droid and the evo and all have had much success with it.
Works fine for me.

I use a class 10, to reduce the current draw. If I were to run it a maximum speed it would be limited by the heat it would generate. So in affect it would be limited by the current it consumes. Not talking about leaks, but overall. Slower sd's are also limited the same way but consume their limit at slower speeds. Since the faster cards are limited (maxed) at higher speeds they consume less at slower speeds, because they are rated at uamps/read/write.
Engadget posted about a class 4 just the other day, due to my post count I can't link. But kingston does have one, even though it's much more expensive. If you're running out of room I would suggest only keeping vital media files with you, and using subsonic to stream anything else.
i wanted the extra space so i can use the phone as an ipod since my zune crashed
Class two is damn slow, I did in fact notice a good speed jump with my class 6

Got my 16gb on eBay for around 28! It is probably class 2 but I don't care lol
I bought one of THESE class 6, 16gb microSD cards, and it seems to be pretty good. No problems so far.
I'm using a class 2 to run apps off of and its plenty fast (also cause im to cheap to buy anything better lol)
Yeah class 2 should be totally fine

tkirton recommends at least a class 4 for Dark Tremor. My G1 would crash on anything less than a class 6 when running apps2sd but that phone is a bit inferior to this one. Not sure if Google has a recommendation for Froyo a2sd.

I have a lot of crashes, so I'm buying a new uSD (Sandisk, as members here recommended) but what other things should I look for? For example, what level?
It's OK, I found the answer. I just was in a rush.
A good uSD with good speed should be Sandisk Level 4, preferably 8GB.

I actually prefer the 16GB one.
Have them from 2's to 32's. If you are going to run from the card for a while, go with the 16 if you can find one under $20. If you are going EMMC look for a 32 as close to $35 as you can find. The 16 seems to strike a balance between boot speed and cost while the 32 gives me enough storage to have all the movies I want on a 2 week trip.

I'm running a 16gig sandisk as well, all 3 of them tested better then any of my 8 gig sandisk cards...which in turn tested better then other brands I had.
The theory was that 32 gig would be better, but so far as I've seen people report it's been a mixed bag.
I'd recommend 16gig class 4 sandisk as optimum with the data available, seems to be where we are at.
That being said, the average 8 gig sandisk card performs well, just the 16's tend to be better.

Just ordered one for my brother and one for myself!
Just a heads-up: as the card class increases, sequential read/write gets faster, but random read/write gets slower. Which means that high class cards are great to take photos and videos but suck for general use, like listening to music, gaming and other uses get slower. You should get a class 4 or 6 for smartphones, never a class 10. Besides, most smartphones can't cap class 4/6 cards transfer rate.

I wouldn't say they suck for general use they have a faster transfer rate which most newer phones are capable of. There really isn't a reason not to got with a higher class unless your phone doesn't support the transfer rate. I personally use a class 10 on my Atrix HD and there is not issues with it. Just my 2 cents.
