Why would anyone buy an MMC card instead of an SD? They seem to be slower and more expensive. My device supports both
donno maybe if they had a digicam or some other device which only supported mmc and wanted to share the cards between them
at least you have an option.
think back to the early days when most PPC's only took one type of card. all people did was complain that it didn't take a certain type of card. progress.
I will get SD as my ppc and my camera is using it can share .....
MMC cost more since they can be used in more devices. As for speed they come just as fast as SD cards.
Many mmc cards I have tried seem to throw up errors when used with my phone.

I see these 66x superfast SD memory cards advertised. Will using one speed up my blue angel?
Can programs use this SD card for operating memory or can they only use the intenal memory?
Does having <5mb avaialable slow down your device?
Fast Sd Cards
Fast Sd cards are only useful for SLR Pro cameras. The rest of the devices are using normal card reader slots. i.e. even if you were to use a fast SD card in the sd card slot,you will only get the normal speed.
by rest of the devices, i mean, all pocket pcs, ppc phones, phones and such devices...... :x
moali77 is correct. it won't make much of a difference in your pda. however, if you use a card reader, or happen to have a digicam that can utilize the speed, you will be better off.
example: i played atlantis redux recently 100mb+ required to be put on your sd card. instead of copying it through activesync, i put it in my usb2.0 card reader, copied it over, in far less time than it would've taken if i did it the other way.
but if you don't plan for much of that, then don't bother paying the premium for a fast card =)
Well I bought a Kingston Elite Pro Secure Digital 1GB, think It's 7.7/8.2MB Write/read
It made my TomTom go way faster planning routes and generally give me better performance from other apps.
I dont know the Top speed for the BA SD Slot, but you should look at the speeds of the card you are planning to buy

Have others experienced similar variations with different SDs?
I recently responded to Wamatt's other posting about SD cards in the BA accessories forum. In it, I've described my experiences with the SD card listed in my sig and BA speed tests I've done with it.
See http://forum.xda-developers.com/viewtopic.php?t=26903 for additional information.
Will it work on the xda IIs?
It may. A user on another forum just reported succesfully using a Tanscend 4gb card in his XV6600 even though he was told it would only support 2gb...http://www.pdaphonehome.com/forums/showthread.php?s=&threadid=61612
Have tested with 2GB SData SD card myself, works fine. Didn't have 4gb but it should work as well.
The SX66 supported SD list was created back when the highest SD card was like 512meg or 1gig, that's why the supported lists are different
hi, thanks for the replies. i see it everything should be fine using a 4gb sd card.
due to the nature of the BA, and as far as i kno all other fairly recent PDAs they will support all current and future SD cards as they don't suffer the limited memory addressing of smaller less complex devices such as normal mobile phones like nokias and digital cameras
i've read somewhere the SD card standard will theoretically go up to 16gb, lets hope they arn't too far away, and that the BA will support it.
Still hoping some random company will develop and release an SDIO USB host though. Damn the BA not having Compact Flash.

Hello!
I want to buy new microSDHC card to my phone and I'm wondering which one is the best.
There are three priorities for me:
- SDHC
- 4GB
- minimum class 6
I found TRANSCEND microSDHC 4GB Class 6 and SILICON POWER 4GB microSDHC CLASS 6. Which one is better? Or maybe you advice something else?
THere is a lot of disscussion about this in this forum. Please search
Sometimes it's hard to find sth when does not speak the native english. Can you please give me the link to this discussion or just post the answer?

Thanks! I've already studied thread nr 1 and 3 and nothing special there. Number 2 is 16GB and 32GB - I need just 4GB and not for WM but for Linux (ext4 and maybe one fat32 partition on it).
well if it's a pda device then it's interface cant keep up with even the normal card speeds
so high speed cards only really matter when you have it connected to a card reader connected to a computer

So it's better to buy class 4 but 8GB that 4GB class 6?
i have not seen any difference personally between 4 & 6. so go for highest capacity.
i have used quite a few brands and all my cards now are sandisk. None of them have given me a problem.
most important thimg regarding performance is to make sure that its genunine. more than 85% of cards sold these days are duplicate.

I don't know jack about linux or 'rooting' onto an sd card, but if I were going to do it, I would make sure that I got the highest quality card available. I've corrupted my 16 G card too many times (mostly my fault, lol) to trust it for running linux off of it. Get something hardy that won't become corrupted, like if the device freezes and you need to reset it. My guess is that you're better off with a smaller card (like the 4 GB one). I'd stay away from a big one if you don't need it.
Basically, it's a huge PITA when your card becomes hopelessly corrupted and you need to back it up and re-format it. I imagine it's a nightmare when your operating system is running off of said card when it becomes corrupted.

That's right!
"most important thimg regarding performance is to make sure that its genunine. more than 85% of cards sold these days are duplicate."
what do you mean? TRANSCEND and SILICON POWER are genuine?
on my purpose,there ARE differences between class 4 and class 6 ,but there are to small differences in speed to pay the double price...I just using class2 Devices (on 3 PDA Phones,2 NDS and an PSP),i never felt there are to slow,yeah on PSP you really fell the difference between an MemoryStick Pro MkII and an Class2 Toshiba MicroSDHC,but for me personally it does not matter -the most of People buy Great Capacity Drives for Media Files right ? ....and Media Files like Movies,Mp3´s etc. running well on Class2 Cards!
Excuse me to say that...but SanDisk Sucks!
a lot of the Sandisk card have Chips from China
(i Don´t know on Class 4 or 6 Cards,but Class2 Card from Sandisk always have Chinese Chips....and there bullsh...)
Japanese Chips (like Cards from Kingston and Toshiba) are a lot better on speed and are a lot more reliable than Chinese Chips
I made my Experiences ,never by SanDisk....
just every Media Market have SanDisk- but that doesn´t mean there are really good..
I have Cards from Siemens,SanDisk,Kingston,Nokia,Toshiba and Motorola (Nokia,Siemens and Motorola are OEM- so i don´t know who produced them)) I have over 20! Cards between 64mb and 16gb---yeah and San Disk are the worst ..dood!
and there IS a Difference between Class4 and 6 Cards,but i think personally there are to less to pay the double Price for it
I have 3 PDA ,2 NDS and an PSP,all of them has Class 2 Cards and i never felt that there are to slow...most of the Devices on the market are to slow to feel the REAL Power of an Class6 Card!

Seems the HD7 uses a Class 2 SDHC card for its internal memory, which is replaceable. I'm surprised it uses such a slow card.
I suspect replacing the card invalidates the warranty though as you need to unscrew the phone and break a seal to get at the slot. Nevertheless you'd end up with a lot more storage, and even 32GB cards are available at class 4 so would be a fair bit faster too.
I remain hopeful that the Venue Pro has gone for the more expensive route of having its 8GB on internal flash chips, leaving the SD card socket free for that nice beefy 32GB card I'm going to put there.
It is odd how MS's own site said they used advanced microSD cards and thus they would be difficult to replace or something. Then we see it's just a class 2. SanDisks are typically a little faster at lower classes than the rest, though.
Two days ago, it happens here
Come one guys, read more please...
You should check the real source here: how dereckcranson was the first to prove us that we can switch any microSD card in our HD7
Okay, I wonder if there are 2 sd card slots in the Focus. Could we switch the 8GB out for 32 and then put a 32 in the 2nd slot?
That would be awesome but I'd be spending just as much on sd cards as I would the phone on an ATT-2year.
If someone get ahold of one, please check!!!

yes it would work if samsung went the route of adding a sd card instead of flash memory as the internal memory. someone would have to open it and see.
I guess the only folks who could figure this out unti after Nov. 8 are the folks with an Omnia 7. Seems to be pretty similar phone.
For giggles, I got my old V3 RAZR and slapped the MicroSD card into it, and I was able to re-format it, and now able to access again.
Catch: because I did not feel like hosing expensive SD cards, I used an old 2GB on my WP7 for testing purposes. That's the problem, max readable in the RAZR's is 2GB, 4GB+ does not work. Just wondering if there might be more information about the RAZR's, can they be modded to read 4gb+?
I guess even a Nokia with support for microsd should be able to read and reformat the cards. The N8 can do this not sure about the others, but they should most definitely be able to reformat it depending upon the max capacity card supported.
