Has anyone done sufficient test on w/c is the best allocation size for our SGS, other posts on the forum for the HD2 says 32k is the best.

Can someone tell me the max capacity XDAII can take for SD card? Can I put either a 512 or 1G card in?
Thanks
Both is possible.
AFAIK there is no limit for SD-cards
FWIW, I'm using a 512MB Panasonic SD card and it seems to be OK.
HTH
since the sd card uses FAT16, I think that the limit would be something like 4GB.
but also I think that it should be possible to format a sdcard with multiple partitions.
just tried, under xp, it is also possible to format an sd card as fat32, the xda will read it too.
format DRIVELETTER: /fs:fat32
in that case the maximum size is 32GB.
Thanks!!!!!! All very useful information... Didn't know that you could specify the format.
At the moment, I find 256mb the most economical, although 512mb are only just slightly more expensive than two 256 cards. 1gb cards though are nearly 3 times the cost of 512 ones.
They are small and easily swapped over, and you can fit a lot on a 256 mb card. I can't see any point in buying a 1gb card until the price drops substantially.
That what I thought initially, but because I could get this 1GB card at a really cheap price, well less than £100 each ;-)
Where can u get a 1gb SD card for less than £100 - pls provide a link
I need 1 gb SD-card for my MDA-II. Which SD-card is the best in concern to write-speed?

I dont think you can use 1MB card on your meching, but if you can i dont mind buying one as well
You absolutely can use a 1GB SD card in the II - I have been using a SanDisk 1GB SD card in mine for several months now and it works flawlessly. It is not the fastest card available, but I have never seen any adverse performance from it. Granted, I do not watch movies with my II on a regular basis.
Is there no comparision available of the write/read-speed of the different 1 gb-cards??
not that i've seen try searching on google
or try looking in the benchmark part of pocket mechanics if they have some 1GB cards there
I'd alsolike to buy 1Gb SD CARD. Does anybody now if the following are any good and if they would work in a XDA1
http://www.memory4more.com/show.cgi?inhalt.htm has 1GB SD-Card Fast 45x Transcend Ultra Performance 45X for 103Euro +tax +shipping
http://www.aria.co.uk has brandless 1GB SD CARD for £48.5 + shipping
2 512 or 4 256 would be a better path imho
first of all with the few 1GB cards the lack of competition would mean slow speed and high price
higher then more of the other cards
a flash card have a limited number of writes before it join its ancestors in the world after having a flash card of 1GB is a bigger investment so having it being worn out is more of a drag
Hello what is the biggest storage an SD can have in prophet and in what speed?
Thanks!
The Prophet can use 4GB cards provided they are not SDHC. (Cards of this size come in both regular and "high capacity" verities).
Because of sever different elements (such as BUS speed, OS, misprints and difference in terms) the speed stated on the card is completely irrelevant to performance.
spare 4gb MMC for prophet
I have a brand new tested and working 4GB MMC card for sale if anyone is interested. Let me know PM me.
Cheers. Raising money for screen repairs to my G4
I have a sandisk 16gb card. I've been reading comments in various threads about formatting to FAT32, should i be doing this for general use?
sorry if this is a dumb question
yes, lots of people recommend fat 32 with 32k block size. (Personally i use 4k block size, but i only have an 8gb card, , reports suggest 32k block size is a little less buggy)
I purchased a Kingston 16 GB class 10 microsd card for my Nexus One. I set up a 1 GB ext3 partition and the rest was fat32. When I tested the performace of the card its read performance was within specifications but its write performance was only about 3 mb/s. I corresponded with Kingston support and they sent me a new one. The new one performed much better but would not work long before it generated so many errors the phone would hang. After I described my configuration to Kingston here is the reply from their technical support.
Hello Lynn,
We do not support any of our flash cards as boot disks or to use to run an OS. These cards are meant to be used in cameras, smartphones, etc as storage devices. It is designed to have a single partition. We suggest you return this card for a refund. If you cannot return this to your place of purchase, please provide a copy of your receipt to see if we can provide a refund for you.
If you have any other questions or concerns, please feel free to reply to this e-mail with full email history. Thank you for using Kingston on-line technical support.

Just means they do not provide support. I have used them in the past and they worked fine
I'm using the same card and its working fine for me
Sent from my Nexus One using XDA App
I have that card too and originally let my Nexus format it. I had write performance of about 700 KB/s - 1.3 MB/s. Awful. Then I formatted it again on Windows with a bigger size of blocks. IIRC, the ideal I found for top speeds was 16 KBytes blocks. Anything higher and it'd slowly go down, anything lower and I had crippled speed. I think it has to do with the size of memory pages on that card.
I have that card and I use it with both a fat and ext3 partition no problem. It is quite slow though (they call this class 10?).
Title != Problem. Fix it.
And most likely what you're experiencing is filesystem format type (block size, clusters, etc) AND block alignment. You'll have to google for the details, but if the card has a 4K physical block size, you'll want the blocks to be 4k and start at the start of each. Otherwise to write 4k you write TWO blocks on the card.
Same deal with SSD's. Partitioning and formatting has be optimized for them to perform their best.
