Hi,
Touch HD have limited speed on microSD card?
I have 8GB Class4 card and i want to buy Class10, i will see any performance increase?
Regards
about the general speeds, those classes express, you can have a look at my unfinished (blueangel) accessories faq here: http://forum.xda-developers.com/showthread.php?t=793862
the speed of the card will be 80Mbit/s instead of 32 MBit/s.
it will not generally improve the speed of your device, since of course, the OS is not on the sd card, but it might access the sd card at a lot of points and slow down slightly, like when you go to the music or photos and videos tab in manila, the card is read for content. apps installed to the sd card might start and run a little faster, and if you have shortcuts to those apps in start menu or as quicklinks, their earlier and faster availability might speed up the phone a little as well.
but this is all about response time, i highly doubt that you have problems listening to music or watching videos from a class4 card, because the possible data rates of music or videos is easily covered with 32MBit/s.

Is there any way to ge tthe camera application to store the pictures and video taken directly onto the SD card instead of internal RAM?
From within the Camera Application click on the "tools" Icon, then click tools (bootom toolbar) and select options from there you have an option to change the folder wher the image is stored....simply select storage card.....or whatever else you deem appropriate. :lol:
Bugger that wa easy; how dim??
However, after some experimentation I have found it is not practical to store video directly to a card - the transfer rate is not fast enough and the video end up jerky.
strange, I wonder if it has anything to do with the type of SD card you are using, I take videos quite regularly at times a good 2-3 minutes in length which I mail to family back home in the UK and I can't say i've exeperienced anything similar to what you mention. I'm using a SanDisk 512 card with the latest ROM release from I-Mate.
My SD is a Kingston 256.
I wonder if it is something to do with the access times of the SD cards??
I know if you spend more you get a card with faster access times.
Or; what resolution are you taking the video clips in? Obviously the larger resolution will require more data throughput and may slow down the 'saving' of data.
Whats stranger: The Kingston 256MB (Toshiba manufactured) are quite good & stable, whereas Sandisk tipically performs worse and is less stable!
So it has to be the resolution used.
I too experience limitations of the datatroughput when capturing video (biggest resolution) directly to SD.
For pictures it is not a problem.
accesstime should be very low on all sd cards not sure if they differ
accesstime is how long the system can get to the data sector it want to read or write
accesstime mean alot more with hd's because they are mechanical
sd and other flash types have very low accesstime
but the read and write thruput differ
you can use pocket mechianics to benchmark and compare with other sd cards in other pda's
I use the large capture size (240x320) i''ve got pocket mechanic on mine so i'll post the benchmark reults when i get a minute
Sandisk are as good as any other, I have been using them now for 1 year in my MDAII and have been operating without any problem, I use them to store Video, photo's and mp3, and change on a daily basis between about 3 different cards (music, video and photo's)
well in the pocketmechanics benchmark sandisk are not as fast as many other brands
Is it really, didn't know that
So which is the fastet 512 SD currently
donno
try looking at the bench's in pocketmechanics
also there looks to be a difference between the
sd speeds of different pda brands
and also i doubt the benchlist in pocket mechanics
is up to date
and then there is the problem with some cards not being compatible
with some pda's
......
all i got is error message when i set it to save directly to sd card
i have lexar 1gb card.
error message is
cannot record the file
36001106:0
fail to ....the film...etc
any idea?
Does it?
Thanx
Igb Card Support
Yes I am using a San Disk Igig card for GPS Maps with no problem.
great ! thanx......
...and I use one for movies!
1 gb
i use it for my MP3s and movies as well.
what about high-speed x60 1G SD card ?
faster then normal speed ?
i'm using 1gig 60x pqi sd card. oftentimes it works. problems encountered: xda2 can't detect the sd card. never done the 3x format yet.
you won't see much in terms of speed in PPC. all these fast speed SD is meant for digital camera & video actually.
I have a 1Gig card by 'Integral' that claims to be high speed. I was having some problems running gps mapping etc from it, though for mp3's and videos it was fine.
I have now bought a 512 SanDisk Ultra 2 card and Tom Tom is much better with this card. Using a multiple file read/write test to copy from the card to itself, the new Sandisk card is significantly quicker, and Tom Tom runs/opens much better than it did with the 1Gig card. So higher speed cards do show an improvement, though not as much as when they are in a device that can take full advantage of the card, like a PC card reader for instance.
I have a x66 PQI 1Gb SD card that I run TomTom3, MP3's and store presentations on. I have had no problems with this card at all. The higher speed of the card does make difference and improves the performance to both the applications and the speed at which data is copied to the card (not using hotsync).
Ive found that some really cheap SD cards have loads of problems.
I bought a cheap card and it was terrible, kept not working, corrupting files etc. I swapped for a 1gig Sandisk, all is well, no problems at all.
I found that the 32meg NOKIA cards given with most new nokia phones a year or so ago dont work. They are totally unreliable.
You get what you pay for, the faster cards are normally more expensive, and ive noticed the difference when copying big files from ram to card.
Get the better cards, its worth it in the long run.
Hi there,
I have an Orange SPV M600 and just about to purchase a new SD card.
One of the things I intend to do is play mp4 films stored on the card.
Has anyone else done this? Do I need a very fast sd card as I'm about to purchase a standard Kingston 2gb SD card.

I have a Lexar Platinum (40x) 1Gb SD card.
I play videos using TCPMP.
When I play Xvid's encoded for the pc (high resolution, this of course requires a high bitrate) at full quality the movement is rather choppy.
However when I re-encode the movies to the Prophets resolution (i.e. a max of 320x240) this of course lowers the bitrate, and at full quality there are no problems with the playback.
I'm not sure if the problem with the high-resolution playback is the Prophet's processor or the speed of the SD card, however when overclocking it does reduce the choppiness.
However I have tried using a 2Gb 150x SD card (forgot the brand, possibly APACER) and my Prophet did not recognise it at all.

i really don't think the speed of the SD card will be the limiting factor here.
that will be the cpu
However, i've heard a lot of horror stories about fast and big SD cards not working on the prophet.
i'm planning to buy a sandisk 2GB ultra II but i'm kinda worried that it will not work.
Can anyone confirm or deny this ? please also mention your version.
thanks,
ban
Had problems with Sandisk ultra ll 1.0gb
spv m600 would not recognise it.

Got a toshiba sd now and works ok.
http://www.toshiba-cards.de/
The one i bought was the blue model
Size 24mm x 32mm x 2.1mm
Maximum Write speed 2Mbytes/s
Maximum Read speed 7Mbytes/s
The speed of the SD card won't have any effect on playback. the bottleneck for video playback on the Prophet is the CPU.
Hello,
When i'm making videos with the camera, and the destination (save folder) is set to the device, the video quality/speed is fine.
But when I set the destination to the SD card, the movie files get laggy when filming fast moving objects or when I quickly move the camera around to film things...
The moviefiles are recorded laggy...
Is there anything I can do to make viderecording to SD card not so laggy? Saving to the device storage works fine, but is limited in storagespace...
Thanks
Could be that you need a higher class of memory card to allow the data to be written to the card at higher speed........
exactly as conan said, depending on the quality of your microsd card the device will be able to write on it only some number of MBs of video to it, if that's lower than the bitrate it won't be able to keep up.
To test it, see what's the write speed on that microsd using a cardreader connected to your pc, a good value should be at least 3MB/s
I have an 8GB HC Class 4 SD Card.
Shouldn't that be sufficiant for normal viderecording?
So I just ordered by G6 and need to buy an sd card for it.
Is it worth buying a really fast SD card like this one:
Lexar Professional 64 GB Class 10 High Performance 1000x microSDXC
(cant post links so just put that into google)
Also I just want it to hold all my photos, videos and music. Dont need it to hold apps so will that work straight out the box or will I have to format things etc???
Thanks
The card will work fine out of the box (phone may want to format it first time if it already isnt, but not a big deal). The speed will make difference if transferring to and from a computer.
