I currently have a 8 gb micro sd card (class 2) and I was wondering whether I would really see a difference in the speed of my phone access programs installed to the micro sd card if I upgraded to a 8 gb (class 6) microsd card?
Inside the phone, not much of a difference, since the limiting factor is the phone and not the card. But when you connect the microSD card to your computer (through the USB cable or using a reader), class 6 will allow you to transfer files to/from the card much faster.

Are you sure the card can be detected properly? do you have a sd card reader to see if windows can detect?
I don't have SD reader
No, i don't have a sd card reader to use with the computer to verify the card, but the sd card is a Kingstom standard mini sd card with him adapter to SD.
The card isn't reconigzed by the prophet and isn't reconigzed by the magician.
The type and size have problems with this models of XDA?
My guess is that the mini-sd to sd card adapter is busted. you should double check with another device to be sure. I doubt sd slot on the pda is busted (have you tried another sd card?). I've used a 2gig sandisk mini-sd car with an adapter in my dopod818pro no problems.
my miniSD adapter is a bit.. wacky. Try this.
Take both of them out.
Take the miniSD out of the adapter
Reinsert it, firmly but not too 'pushy'.
Now, the trick here, when you insert both of then into your phone, try not to push it on the miniSD, instead, push it on both side of the adaptor (eg ONLY touch the adapter when pushing into the phone, and balance it (left and right)).
So I recently bought an 8GB Class 6 MicroSD card from Microcenter (One of the generic Microcenter ones) and when I plug it into my Vista x64 machine and try to navigate to it, explorer.exe hangs and freezes until I unplug it. Ubuntu recognizes it, but it will not show up in GPartEd, mind you this is with two card readers on different computers. The phone recognizes it but won't save anything to it.
And on top of that I had my dad exchange the card out for another one because it is closer to where he works (Microcenter is about 20 minutes away), and they both do the same thing, has anyone experienced this also?
Are you using an SDHC card reader? Those cards are SDHC. Make sure your card reader has SDHC letters on it.
SDHC is not the same as a SD card. Older card readers will hang the OS.
I went to a MicroCenter and asked about the $50 (or so) card and they told me that it was actually just a class 2 so I refused to buy it. Instead I got a NAME BRAND (AData) from Newegg for the same price and I love it! I don't have any issues.
But it sounds like you need a new or different SDHC adapter.
Edit: Have you tried just using the phone as the adapter by mounting it?
If you can access the card that way then my guess is that it's not the card.

I can confirm this. I have a 4 GB SDHC card that will not work in my current reader. I got a smaller regular non-high-density card to recover with. Either get a small card (2 GB) or upgrade your reader.
I did find out that I needed an SDHC reader. I just bought one and it works great.
Hi I need more space for my duo 11 and the cheapest way i believe is to buy a micro sd card to increase the size(Don't know if i can swap my hard drive from 128gb to 256gb). I spotted this micro sd card which is pretty good but don't know if i can utilise it to its maximum speed. The card is "Samsung UHS-1 Class10 PRO Micro SD XC 64GB Memory Card", I know duo 11 supports SD XC but it also needs to support UHS-1 for it to use it up to its maximum speed.
On a side note it says
-Read Speed: Up to 70MB/s
-Write Speed: Up to 20MB/s
Does take mean if i transfer files out of the sd card it can go up to 70mb/s and if i want to transfer files from my hard drive to the sd card the transfer speed would be 20mb/s??
Thanks in advance!
That would be the correct speeds assuming all is perfect and no overhead.
You also need to verify that the reader in the Sony is not connected through USB 2.0 or you wouldn't see 70MB/sec reads, more along the lines of 30-35MB/sec.
The duo uses sd cards not microsd. You can use a microsd card with an adapter but a sd card will be cheaper.
I have a 256gb sd card in mine and it works but it's not particularly fast.

That would be the limiting factor as far as the SD card is concerned yes. Operating system overhead would slightly reduce that. Also there would be a limiting factor in what the hard drive read and write speeds are or memory stick or whatever it is the files are being transferred to and from.
My old microSD is broken in a few places, it works, but it might be causing slowdowns and glitchy behavior. This card is Sandisk class 2, now i have two Transend cards 8G and 16G class 10 and Team 8G class 6, none of these 3 are recognized by the phone. I umount my current card though the settings menu, and when i insert a new card the phone gives no indication that it has noticed it. I plug the old card back in, notices and mounts as usual.
Any one else having similar problems? Is the phone not compatible with Transend (Team)? Is it a problem with class? Is the card reader broken in my phone? (can't be if it reads the old card)
update: i tested two more cards 4G class 4 Transend and 4G class 4 Verbatim. Transend is once again ignored, Verbatim mounted just fine. There must be some difference between Transend and Sandisk/Verbatim...
My wife was having having trouble playing songs from her micro sd card (the tracks kept skipping a beat or so), so she bought a new micro sd card. She used the micro sd card for a few days and today the smartphone would not see the micro sd card when she went to "storage". I've tested it on my cellphone and on my computer and none could detect the micro sd card. Could the cellphone have damaged the micro sd card somehow or is this most likely a coincidence?
Personally I think if it's a new card it's just a bad card. It happens.
OK few questions is the SD card SanDisk?
How large is it?
If it is a SanDisk then it is possible for some issues just read up on it.
