Hi, sorry if this is a double post. I did look around but could not find much info.
I'm interested to know how well the new 16GB MicroSD cards work on the Xperia. Anyone using one of these? My main concern is that they all seem to only be class 2 atm. Is this too slow to run apps and my videos stored on it etc?
Should I wait till a class 4 16GB card comes out?
Thanks
Edit: I also noticed that SanDisk has a “Mobile Ultra” memory card range. Only up to 8GB though. Anyone using one of these? Is there a big difference in speeds?
i don't think it matters in a phone.
I ordered the eact same Mobile Ultra card today. Should be here saturday, so I will tell when I get it. But assuming it's Class 6 card, it should be fast. I wouldn't go with Class 2, since it's slow. But as Jabe says, it might not matter on the phone.
So as at now no one's using a 16GB yet?
Give me a week or 2. I'm planning on ordering the Sandisk one.
Sandisk Mobile Ultra is good, and it's what I am using for X1. Since it's class 6, the read/write speed is about 20/16 mb/s, which is much faster than class 2. If you wanna watch video storaged in card, this one is your first choice.

Note that the speed in the end is depending on the host itself. If the host is slow, even if you use class 6 memory card, it's not going to make any difference. Personally I believe the phone itself would be the bottleneck and not the memory card.
I know it's not totally relevant but just for reference, take a look at the link below. As you can see the speed of class 2 and 6 are pretty identical as it's limited by the host. This is even with a dedicated memory card reader. Compare the 2nd and 4th entries from the bottom.

If that's the case, what's the optimal speed supported by X1?
So anyone able to compare the 2 classes

I'm using a 16GB Class 2 at the moment. No probs with apps or music. But I have no videos on the card...
with normal sd cards the pdas were mostly not able to transfer as fast as the sd card supported
as the sd interface in onchip and not that fast
would like to see some tests if the same hold true with newer pda's and class X microSD cards
anyone able to follow this up yet?
I'm using a Sandisk 8gb Class 4 HC. No problems with speed or data read/write (on the phone itself).
Using the phone as a disk drive though (not activesync) is noticeably slower than using a USB adapter, *suggesting* the phone itself is the bottleneck?
I'm using a SanDisk 8GB Class II Card and I had no problems with photos, videos or music so far.
Don't think a Class 4 or 6 is worth the price in a mobile phone.
I got my 16GB Microsdhc today. And everything works. Sad thing is it only shows 15GB.
I find no difference in speed between my 8G class 6 and 16G class 2 (both from Sandisk)

it's 15G probably because of the way how "G" is being calculated. 16,000,000,000 = 16,000,000,000/(1024*1024*1024) = 14.9GB
im using a 8g class 4 card, music, apps and vids work great.
just a quick question, the x1 has a sd card limit of 32g, when a larger card comes out like the 128gb card that sandisk has said will come out, could windows mobile have a update so that it can read it or is limited to the reader hardware inside the x1
I have 2 cards: Sandisk 16GB Class 2 and Kingston 8GB class 4.
I use Sandisk in Xperia, and the speed is more than sufficient. It reaches 12-15 MB/s writing on USB adapter. Reading - it's no problem reaching even more. So it's ok, speed wise.
I don't think you would need more speed in Xperia )
There's no HD video recording option in there )
one can use pocket mechanics to benchmark the sdcard speed
if the results are lower i would suspect it show the bottleneck speed
of the sd interface of the qualcomm cpu in x1
I have a 16gb micro sdhc and some .avi videos lag (highish quality). Specifically, top gear season 12 episodes from finalgear.com. it might be the divx client though, Im using the WM 6 Pro version available on the divx website.
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...
~Jasecloud4
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

$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.
I got a 32Gb MicroSDHC class-10 memorette card.
I verified the speed with a card reader + h2testw that write speed is : 14.7MByte/sec
read speed: 17.5MByte/sec
But when I used the class10 card in tmobile HD2, I am shocked.
When I copy a 720MB movie the write speed is about 4MByte/sec.
h2testw program when used on hd2 connected to PC, showed write speed as 4.8 MByte/sec only.
It needs to be noted the same card when tested with h2testw and a card reader gave 14MByte/sec but gives less than 4.5MB/sec on HD2.
How to fix this problem of HD2 microsd card speed!
Looks like HD2 usb controller has some problem.
the card is indeed class-10.
Please let me know a solution to this problem on HD2.

The HD2 doesn't read or write to sd cards at that high of speed... that's why it's pointless using class 6 or 10 cards in a HD2. I think most phones are like that. Class 6 and 10 cards are mainly used for digital cameras, where having high sequential write speeds matters.

I have earlier used a nokia 5800 xpressmusic phone with a class 6 16GB card.
The data transfer speeds were higher than HD2.
Generalizing from a single instance (HD2 scenario) may not be correct.
I'm going to go with that the HD2 does not transfer faster than 5.3 MB/sec between the PC and the phone regardless of what the internal transfer rate between the phone and card is.
Using a class 6 card myself, i have noticed that the phone is much more responsive than it was with the class 2 card in there and movies play without stuttering from the class 6 card and applications launch quicker.
my nokia n81 8gb did 8MB/sec from internal 8GB and so did my KM900. The KM900 did 6.2MB from the same classs 6 card
I was under the impression the HD2 maxed at 16 gig. Maybe that's the problem?
Like zarathustrax said, the HD2 isn't capable of read/write any higher than a class 4 card. I think somewhere on the EVO forum there's a fix to unlock the read/write capability for a higher speed but I dunno if anyone here has tried the fix, or if it even works for the HD2 at all.

This is not true. I've copied large files at over 10MB/s directly to the phone. I can't vouch for every hd2 though as it's quite possible they have different hardware. Also the speed drops dramatically if you're copying many smaller files.
I am thinking to buy memorette 32 gb microsd class 10 for my HD2.
As far as I have understood:
1) No matther what I cannot use it fully Class 10 speed when connected to HD2
2) When I connect it to my PC with card reader I can fully use class 10 speed.
I have sandial 8 gb class 2. When I connect it to my pc with card reader and transfering large amount of data (150+ MB), it cease to operate. I have to reconnect it. Then I shuld transfer in less amount of data or reduce copy speed (such as UltraCopy) . I think that is a safety issue for preventing disk from get burned. My question is, will I possibly have some issues with memorette or some other class 10 cards?
Also would it not better using class 10 card in HD2 for using on SD installed Operating System instead of class 6 or 4?
I would appriciate if someone return about memorette. I have never heard about that trademark. I am planning to bid on ebay today.

A good quality class 2 or 4 sd card is usually better for running an operating system off of, as lower class cards tend to have faster random access speed and better random read/write speeds. Class 6 and 10 sd cards are designed to have a higher sequential write speed, but to achieve these higher speeds, the card initializes the part of the card that's about to be used. The initialization takes some extra time to get started, but boosts the sequential write/read speed so it's great for digital cameras or writing files sequentially.
But when it comes to using the card to run an OS off of, like android or wp7, or using the card to run apps off of, you are going to be reading and writing many small bits of data from different parts of the card. When it comes to this, you need a card that has a good random access speed and random read/write speeds. A high class card that is tweaked to have high sequential read/write speeds ends up being slower because it keeps initializing each part of the card before accessing it, while the lower class 2 or 4 card that doesn't do the initialization is a lot quicker accessing many small parts of the card because it doesn't have that extra step... but they don't get the speed boosts with sequential read/write.
Many people just assume that a higher class card is always going to be better, but this isn't true at all. It all depends on what you are using the card for. Higher class 6 or 10 cards are perfect for digital cameras, recording video, or transferring large files, etc... if you are going to be doing sequential reading or writing, higher class is better.
But for running apps off of, or running an OS off of, or using it as internal memory for an OS like wp7, or anything that will be accessing many parts of the card quickly or reading many small bits of data, etc., you want a card with a good random access speed and random read/write speeds, and that is something that is not rated on cards... but generally lower class cards are better than higher class cards... especially if you get a good quality brand, like sandisk. Sandisk class 2 and 4 are very good cards for random access speeds.
I hope some of you find this info useful and stop assuming a higher class card means better for all situations.

My question is, will I possibly have some issues with memorette or some other class 10 cards?
Also would it not better using class 10 card in HD2 for using on SD installed Operating System instead of class 6 or 4?
I would appriciate if someone return about memorette. I have never heard about that trademark. I am planning to bid on ebay today.

I am using memorette class 10 32GB microsd currently.
Its affordable and is fully working. I have tested to full capacity read/write using h2testw as I wrote in an earlier post.
Just check the seller's feedback and the description though.
I use TEAM micro sd class 10 on my hero,but after a month my sd card write speed is only 2MB/s.
At the first time,it reach 11MB/s when i tested it with h2testw and sd speed test on my handset.
I only use 640MB for app2sd (ext2) without swap cache.
Could someone explain to me what was happen to my sd card?
Sorry for my bad English
Sorry if this was already asked but I tried searching. What type of class micro sd card will I actually benefit from? A samsung class 4 32gb is out there for a good price but if the tablet will actually take advantage of a class 10 I would get one of those.
for the most part it will not. Except in moving large files to and from the card.maybe playing movies from the card.but even movies are OK on 4.6 class cards..if you could run apps or have there data from SD card then it would be a big improvement. I have used a 8 gig class 4 and now have a 32gig class 10.can't tell much difference other then when pushing roms and other large files to my tablet over USB.
I would say get 6 minimum but if you have the cash faster is always better. Just don't go out and spend the money if you have a class 4card.
Im sure you will hear diffeent from others.
Not really. I have 5 sd's, and no difference between class4 and class 10.
Up to a certain size that is. Anything more than 16gb, and I would move to a class 10.
Rumor has it, that you can run a 64gb. If you partition it with Partition Magic.
I think it depends on what you are using the card for. I don't think it is the tablet that would take advantage as much as a particular app that would. If you were using apps that required fast read/write access to the card (and you were actually using the card as opposed to the internal memory) then the faster card would be best. Keep in mind that not all class 10s are the same so also make sure to look at some of the benchmarks for the different cards. I know in terms of photography and hd video captures that a higher class card really does make a difference...but that is just an example of a real use application.
Hope that made sense.
