Somebody says it's useless to have a high speed SD card on Pocket PC. A general one is ok and high speed SD performs high speed on DC only. I'm thinking of buying the SanDisk Ultra II 512MB. Any idea?
yes the speed does differ most of all write speed
if you install pocket mechanic you can bench your card and compare with tons of different brands in different pda's
I've read about people warning us off Sandisk, as compatibility and quality seem to be inconsistent. I've used Lexar 32x high-speed SD cards in my iPAQ 3850 and in my O2 XDA2 and the speed is much quicker in both to standard SD cards.

Greetings all.
After much thought, I opted for a Magician (yet to arrive). The next step is purchase as large an SD card that my pocket can afford, and it is here that some advice would be appreciated. A 1GB card can be purchased here in England for around £55 upwards. All well and good. However, how do these budget cards measure up in terms of speed?
A second thought which struck me was that the same card could double up to be used in my digital camera. Doubtless many of you also own a digital camera. I had already bought a 256MB card for the camera, but was always perplexed by the amount of time it took the camera to be ready for another shot (in highest quality mode). It is only now that I belatedly realise that the delay must have been due to a slow write speed.
So there you have it: I would prefer a high speed write card (4 megapixel photos) which can also be used to play mp3s on the Magician. Are there any prime 1GB candidates that spring to mind? I have yet to find a good website offering comparisons of a wide range of SD cards...
look at the program pocket mechianics it let you benchmark your system and compare to other pda's and or with many SD cards
doubt it's uptodate though
and at least for the xda2 and many other pda's it's the interface which is bottleneck not the sd cards
sd card speed seem to matter the most when you are using usb2 sd card readers
I'll take a look at pocket mechanics to benchmark my existing card. What about for choosing a new and, as yet, unacquired card? Are there any recommendations?
I have heard good things about the SanDisk Ultra II range. Unfortunately, the 2GB version cannot be bought for less than ~£180 here in England. Are these cheaper in the States?
Hi. I'm about to buy a new SD card and was wondering if I should stick to the cheaper generic 60X 1GB card or get the more expensive 150X 1GB card? I'm willing to spend a little bit more if the 150X card will boost the performance of my XDA II (since most of my files and apps are on the storage card). Any advice will be greatly appreciated. Thanks.
no the sd interface of pda's cant keep up with even normal sd cards speeds
What is the "normal" speed of SD cards?
about 1MB/sec if you're lucky i think
1 mb per sec?!? Wow that is slow
you can use pocket mechanics to benchmark yourself and compare with other cards and pda's in it's db
Looking to buy a Kingston 8GB SDHC card.
Will there be any performance gain with using a CLASS 4 or 6 SDHC expansion card with my P3600 (Trinity) or is the read / write performance limited by the phone's chipset?
no the sd interfaces of these pda's cant even keep up with normal speed sd's
highspeed ones only help any for sdreaders
Thanks Rudegar
Just a quick question about memory cards. I have read on this forum that it is possible to run a 16gb class 6 high capacity secure digital card in a HTC Universal running a Windowmobile 6 Rom 2.09.01_BL__B_V1; can the same also be said for a 16gb class 4 high capacity secure digital card? I have found one on the net that I am thinking of buying but thought to ask before doing so. The item is http://www.amazon.co.uk/Integral-16Gb-SDHC-Class-Card/dp/B000ZOVB0Y/ref=pd_sbs_ce_title_9
I have a contract with O2 and have been informed I am due an upgrade, I have had a look at the O2 Orbit 2, nice looking device; what are the other names for this device as I am unsure?
Thanks for viewing and replies welcome.
Yes ,it support my Toshiba 8gb class4 very well!
the "class" on SDHC cards only marks their speed.
it's the "guaranteed minimum consecutive write speed" in MByte/s
So a class 6 card must be able to handle 6MB/s write speed. It may be a lot faster, but if it's slower you can return it as defective.
The only difference between a class 2 and a class 6 card is that one uses better memory chips than the other, so it can receive/transmit data faster. The interface / layout / pinout / logic / data structure is all the same.
It's like 12x and 52x CD-R. You can use both in any drive that supports either, just the one gets the job done a little faster than the other.
Of course that the card can handle 30MB/s doesn't neccessarily mean your universal can, but it should work (at the universals maximum speed) nontheless.
I'm using a sandisc 16GB SHDC class 6 card at the moment with a Crossbow rom, runs very well.
I am going to buy myself a 64GB micro sd card. I guess I will go with sandisk. But as there are certain sd types there come certain speeds. Such as UHS-ll, UHS-I ,and microSDXC. Now I want to make sure that my phone (SM-G3858) Galaxy Beam 2 is able to do r/w at certain speed levels. But how can I determine that? How can I check if the sd card slot takes UHS-I? I can do a micro sd card speed check when I already bought the sd card (with some apps). But is there any way to check the speed compability BEFORE you even buy the sd card?
I did 3 speeds test on my kingston 18GB MicroSDHC/SDHC Class 10 and the sd benchmark tests were ranging from (max): Read 401,31MB/s Write 10,45MB/s (400 seemed a lot to me, but thats what it said) So that would mean my phone supports at least UHS-l?
I was thinking to buy either the Sandisk Extreme at 45r/45w, the Sandisk Ultra Plus at 40r/lower write or the Sandisk Ultra at 30r/lower write. Or should I go with another brand? Any help is appreciated
thanks
:good:
EDIT: After searching for several hours to find the best 64GB micro sd card I decided to go for the Samsung Evo 64GB. It has full 5 star reviews on amazon and the price was way better than the Sandisk extreme plus. (I paid 37 euros including shipping) This is the best review I found:
"This is a very fast card, particularly suited to not only transferring files quickly but also running as a phone or tablet card for applications as well.
In phones and tablets one of the most important things is not just the transfer speed but also the IOPs that the card can deliver. Many class 10 cards have great transfer speeds but terrible and I mean terrible IOPs, often a 5 year old card easily out performs them in IOPs.
This card delivers in both areas, fast class 10 transfer speeds 23mb read, 15mb write but also 482 write IOPs and 1668 read IOPs.
That's IOP speeds that are slower than an SSD but way faster than a hard disk. Bare in mind that some class 10 cards give 4 write IOPs and you can see why I'm impressed. The only card I have seen outperform it in IOPs it the SanDisk Extreme Pro and they are seriously expensive and not available in 64gb. Testing against the third SanDisk I have, a 32gb ultra, is almost funny as the ultra only gives 15 write IOPs under the same conditions, making this card 30 times faster.
What does this mean for normal use, well it translates into an excellent general purpose card, that even if it doesn't have the official fastest transfer speeds will actually perform much better in the real world. Which is why its getting such rave reviews on here for speed (so long as you get a genuine one!)
This was tested in my Dell Venue 8 tablet using the built in card reader. For the techies (if you've got this far then I assume you are)I am actually using it to run Server 2012 virtual machines in VMWare workstation and the performance is surprisingly good, I would even call it snappy!

So anyways..At one point I´ll wait until the price of the Sandisk 128 GB Ultra plus card drops, then check for benchmarks and try out that one. Enjoy the info, im off
Sandisk is having quality issues with 64Gb cards, with many consumers reporting dead cards in a few months.
The Samsung you have choosen is awesome, along with transcend which are rock solid.
