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 am debating at the moment weather to get a 8GB Class 6 Micro SD or the 16gb Class 2 card?
Will the faster card be a better choice if I am storing movies on it? I know there is the SDHC hack on here to help with the transfer speed or whatever so would that be enough to help in movie playback with the 16gb card?
Help well confused lol.

me too what did you end up doing?
I am considering to buy a 16gb class 6 microSDHC card, would that be an overkill? (not the size of course, Im going to put a lot music etc, but would class 2 or 4 speed be enough for it?
Thanks in advance,

For anyone that has a galaxy s, is there any difference between onboard memory and microSD in the time it takes to select a video & play it?
The internal memory will be faster. How much faster, I don't know.
Now that a few more people have the phone, can anyone comment? Thanks.
Well I have not tried playing any camera videos or movie files from the Galaxy's inbuilt sdcard but from the MicroSD they both play fine.
The card I use is a 16GB Sandisk Mobile Ultra Class 4

I have Sandisk ultra 16GB class 4, i made a test, I copied the same file "700mb" on the external and the internal and flushed the memory.
and use the "my file" app to select and play it.
it's the same speed as i can't tell the different.
maybe because the sandisk sd is fast in reading as the internal sd
Awesome, thanks.
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.
