What is the maximum capacity of SD cards that XDA supports?
Can I put 128MB SD card in XDA?
If you have used the search button or looked on other postings you'll have seen that the maximum capacity used in the XDA is in the moment at 512MB
(I don't now, if any bigger is available...)
So you can use your "small"SD card with 128 megs without problems....

I want to buy a sd card but i m not sure which one is better
Lexar SD 256MB 32X Speed (about 70$) or
SanDisk 512MB SD (about 106$)
512 mb looks great choice but the other is high speed ???????????
i need your comments
sandisk is not know for it's speed as it is
but very fast SD cards will never reach their top speed
in the xda their sd interface is not fast enough
if you search the forum you'll find some guy who did some tests
think the sd card did 10MB /sec in the sdcard reader on the pc
and only about 1.3 MB /sec in the xda
not all that impressive
And for the XDAII? Waht is the speed of the port?
well i forget if it were tests made on the xda1 or 2
but arm 200 which the xda 1 have dont have a nativ interface
for sd so it use an external chip and the xcale 400 that the
xda2 have have a native interface
too bad that nativ interface is WAY slower then the external chips
pda's used to use
there were some posts before xmas about places where the xda it would be way faster then the xda2
but that was in the old forum not sure if those posts are lost now
here is a line from a writing about xscale's performance on ipaq
which i asume would be the same for xda2 unless they added a mem controller and dident use the internal xscale one
Because the XScale CPU itself contains an MMC controller that supports SD and SDIO, and that's almost certainly what HP is using, rather than adding a chip of their own. MMC and SD are very similar, almost identical. The difference is that MMC uses a 1-bit data bus, and SD uses a 4-bit bus. See, we're back to buses again. Since the XScale's controller is MMC-based, the new iPAQs will have 1-bit bus transfer rates. Hang on to your CF sleeves for big data.

I got a Billington 512MB SD card 40x speed. It is OK. Cost about SGD$245.
Hi all,
I need your opinion. I'm planning to buy a Sandisk 512MB SD Card. How much does it compare with the 256SD Card with regards to speed? Is reading/writing much slower because of its bigger size? BTW my device is XDA. Thanks
My understanding of speed diffs
I don't think 256 vs 512 will make speed differences. The speed differences come between specific cards. My brief research yesterday suggested to me that SanDisk are kinda slow, even the Ultra II cards. It seems the fastest card, consistently, is the Panasonic. I have a plain 256MB sandisk card it PocketMechanic benchmarks it at 0.7x. I will test my new Panasonic card when it arrives later today (hopefully!).
Just for comparison, Lexar 32x cards are rated at 4.8MB/s, the Panasonic is supposedly rated at 10MB/s.
Another data point, I saw a discussion on Amazon.com reviews about the SanDisk 512 and somebody stating it was faster than the 256.
All this leads to: you really need to benchmark the specific cards you are interested in to see if they meet your speed needs. Speed is really variable, people talking about a single process that takes 45 minutes on one card and just like 1 minute on another card (brand).
Got the panasonic card
I got the panasonic card. It writes at "2.9x" as opposed to "0.7x" I got with the stock sandisk. That is better than 4 times the speed. Benchmarked using Pocket Mechanic on an XDA.
Hey guys
Recently I got a new 8Gb Kingston microSD as a present. On it, it says the card is class 4, which should be faster than the one we get with our HDs. Copying to and from it seems dreadfuly slow for some reason, slower than the sandisk one. Is there any special way to format it to gain more speed, or special setting for the format? Thanks.
If someone wrote от a label: speed is xxx, it does not mean, that this card is really fast. And, as far as I know you cannot increase your card speed by software.
Sandisk is more trustful for me than Kingston. I don't insist, just my own experience.
As a matter of fact, when I got my HD, card included was class 6 Transcend, fast enough.
Of course you can try full format, say, using a Big Brother's cardreader.
while formating try changing cluster size to 64kb instead of 32kb default
hopefully it will solve the problem ......
There is a speed bottle neck on the phone. So the speed of SD Card is not so important on phone rather tban on compufer. If I am not wrong, HTC HD phone max out at class 2
Looking for people who have benchmarked their sd cards.
I have a fairly old 32gb generic sd card, it doesn't even have a speed rating on it.
I want to use bootmanager but I'm not sure this old card is fast enough to boot off of. I'm testing with SD tools on my tbolt
I get about 6 mb/s write speed
I get about 7-9 mb/s read speed in SD tools,
I know class 10 cards can vary wildly in performance and quailty
I am wondering if anyone has recommendations for the best quality card
with the highest read/write speeds, I want to get a new card but I don't want to pay a lot of money for a card that is only marginally better than mine.
i just downloaded that program to help you out,
got
7.0 read speed (peak was 8.6)
17.6 write speed
I am a long time user for boot manager and havent had any lag issues with this sd card
sd card is
32 gb
sandisk
class 4
came with my tbolt
