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!)

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
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
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).

I want to get myself a new SD Card for my Magician:
I will choose between a standard 1 GB SD Card and the SanDisk UltraII SD 1GB
First of all, does it really make the difference if i take the UltraII? How much faster is it anyway? It would cost me almost 50% more.
Secondly, can the Magician even handle the Ultra? Are cards up to 2GB even supported?
Or should I consider a bigger card?
Currently I've got a 256 Sandisk standard....

In general you probably won't see the speed deference between the basic and ultra on a PDA, because of the speed of the interface.
If you use a card reader (using USB 2 interface) then you will see the speed increase.
Personally, I've just bought a Sandisk 1GB Ultra plus card:
http://www.picstop.co.uk/Secure-Digital-(SD)/SanDisk-Ultra-II-(USB)-SD-Plus-Card---1GB
Will have to wait and see how good it is!
Apparently 4GB sd cards are coming soon, which should drop the price of the 1GB cards even further.

If you going with a 2gb card - go with the sandisk ultra... I purchased an A-Data 2gb 150x and it does not work.
SanDisk Ultra are good cards.
Has anybody benchmarked and mini SD Cards compatible with the wizard.
I am thinking about waiting for the 1GB 66x mini sd card if it helps speed up the wizard in running programs.
any idea of performance 's of mini sd cards?
is the mini sd card slower or faster then the built in memory?
any recomendations of mini sd card for the wizard ?
I doubt the Wizard would have the hardware to take advantage of high speed cards. High speed cards are typically for devices like highend digicams and video cameras that would utilise the extra speed.
