one big mmc card

http://www.pdagold.com/articles/detail.asp?a=159
seems to be kinda fast aswell
wonder if the xda's would support it

If the Xda does support it, I WANT ONE!!!
But the only thing is I'm sure they would cost an abosulte fortune!!

Read speed about 150X (22.5MB/s)!
Write speed greater than 120X (18MB/s)!
Compatible with most Secure Digital (SD) slots used by mobile phones, digital cameras, and other portable digital devices!
WoOoOoOoOoOoOoW
I want this MMC!! :lol:

well the xda2 is not fast enough to
do
Read speed about 150X (22.5MB/s)!
Write speed greater than 120X (18MB/s)!
even if the card support it

ohh really?? :shock:
so whats the maximum read/write speed an XDA can operate with when using MMC ? :roll:

pocket mechanic can benchmark cards

SD Ultra card

Can we use the Sandisk 'Ultra' line? If yes, does anybody know if the faster transfer rate of the Ultra card is supported by the XDA?

try using pocketmecanics it got a benchmark tool
and that seem to show that
the xda2 at least use the pretty slow intel xcale internal sd interface
making the xda1 faster when it comes to sd speed
with mechanics you can compare your result with a list of pda's with different sd cards
non of them ever reach ultra speeds
heck they dont even reach the max speed of normal sd cards
if you compare the speed with the same card in a SD card reader
but that dont mean there is not difference in speed
like Sandisk is the slowest thing ever

I'm using a Panasonic 512MB SD Card and it's supposedly faster (and better) than the SanDisk Ultra.
YMMV

Speed of SD slot

Hi, does anyone know what the max supported speed is? I can buy a 2 mb/s write and 3 mb/s read 1 GB SD card or a 5mb/s write and 6 mb/s read for just 10€ more.
So my question is, should I pay 10€ more?

Buy the fastest
Because ifyou by a usb card reader you will be able to copy data faster.

So it only matters if I also buy a cardreader?

Hmm i wondering about this myself even, whats the different . Can anyone answer exact how fast the qtek s100 writes and read. It must be some meaning of faster memeory card. Example Simpletech has 10/10mb fast and writing speed . And Sandisk 1.5/5mb i think. Dont the phone be faster with faster memory card???? please someone?

the card reader is really slow
i've bought a Sandisk 1GB Extreme III SD card, but in fact it is slower that a normal 512MB Kingston SD card, to bad... (both around the 1MB/s with PocketMechanic SD benchmarking).

Slow SD interface?

I have a Sandisk Wifi + 256 mb card in my MDA Compact and eventhough the driver and such work flawlessly, the wifi performance is very disappointing. With an internet download benchmark I got about 26KB/s througput. I knew the card wasn't going to be fast before I bought it, but I was expecting to get at least something like 100KB/s.
At first I thought the problem was with the card itself, but when I tested an Sandisk Ultra II 256MB SD Memory card with pocket mechanic I noticed that the throughput to the memory card was also very low (0.26MB/s).
The throughput to the supplied mini SD was even worse (0.10MB/s).
Now I am wondering, is there a general problem with the SD bus interface? Can someone verify these results for me?
Or am I mistaken and should I not expect anything more? I did a full SPB benchmark on the device itself and the numbers were even a little better than to some posted in a review.
TIA!

yeah the jam seems to be slow with cards for some reason?!?!
i got a simpletech 10mb read/write one of the fastest and best cards out and i used to get over 1mb read/write on the xda2 with it but on the jam it gets 0.26mb write and 0.78mb read
with my ultra 60x 1gb it only gets 0.23 read and 0.63 write :\
seems so slow

I get similar speeds to this on my XDA II but the SD Card is much faster in an external USB 2.0 reader/writer.
Even worse, I bought a standard speed SanDisk 512k SD card that is so slow, the XDA II can not write to it at all!
I now only buy Ultra 60x or faster SD cards even though you don't get anything like that in performance in the O2 device itself - just reliablilty.
I use an external SD card reader/writer to load it with MP3s etc. I suffer 20 minute backups with Sprite Backup to SD card daily as I have no choice. (I also back up to 2 PCs as well daily - not much faster).

512MB SD: Panasonic Highspeed vs Sandisk UltraII...

Hi guys!
I've got 2 512M SD memory card:
- Sandisk UltraII 512MB
- Panasonic High speed 512MB
...and I've got 2 device:
- i-mate Jam (QTEK S100)
- Canon PowerShot SD300 camera
Waht's the difference between the 2 SD?
In your opinion the speed are identical?
Is it better to put the Sandisk into Jam or into the camera?

Hi
I read a long discussion about SD card speeds on this site ages ago.. as i understand it, PPC can only read and write at a FRACTION of a slow/normal SD cards read/write speed, so it really makes no difference.. might as well put the biggest, cheapest card you can in it as anything alse is a waste of a memory card...
My own limited experince with a few sd cards i have (bog standard up to sandisk xtreeme III) shows no difference in speed across the cards.
Lovely caemra you have by the way

Thanks!!
Well... I understand that in ppc I can put the slower one but...
Sandisk Ultra II vs Pnasonic highspeed?
What is the faster? (I'll put the faster in my camera!)
