Hands Off Slow Sd Cards

[chaos engineer]

I just want to warn you as some applications do not work properly with slow sd cards. I bought the ordinary 1 gig card from Sandisk

The following problems occured with this product:

- dvd divx rips of 600 MB do not work in the movie player
- neogeo cd emulator: it is not possible to load zipped roms
- psx emulator: roms do not load (I tried tekken 3)

Then I tried the same applications with my fast Kingston Elite Pro High-Speed 1GB card,

...and the problems mentioned above did not occur anymore. I guess the crashes are because it takes too much time to load the data.

One advantage of the Sandisk card is the possibility to flash firmware updates. This did not work with the Kingston card.

I do not want to blame Sandisk, as I know they offer faster cards too, but I think this problem is worth mentioning and maybe some of you have made similar experiences.

i've got a integral 1gb card which isnt advertised as an actual speed ( ergo, slow ).

has been fine with all of the above.

anyone else?

i dont belive speed makes any difference yes, the sd driver is still only 1bit and dead slow.

but what could then be the reason? I have got two card readers. I copied the content of the Sandisk straight to the Kingston, and the stuff worked. Maybe something else is faulty with my Sandisk card.

What speed are the Sandisks? Ive looked and Ive not seen it anywhere, on any sites, ever! Are they 80x?

this is the official procuct page.

They do not mention the speed. I guess 0.5x.

if this is a problem then i'm screwed. i preordered the sandisk with the unit, and they're not particularly cheap.

It doesn't appear to be that simple. My 1Gb Sandisk runs all the things you've listed just fine, but doesn't let me flash the firmware from it. It seems to be the specific combination of card, reader, OS and formatting technique that determines whether you have problemsor not. Hopefully future firmware will iron it out and provide more solid SD support.

maybe danchamp is right, and this is a problem of a combination of different factors. But still, I think the Sandisk was a bad deal. It even provoques problems in my pocket pc because it is just too slow. but there is still hope that my card is just a faulty one.

Somebody told me that the ordinary sankdisks are slower than other low budget sd cards.

godamn, i ordered the sandisk card with my unit from gbax too..i really hope this isnt a problem or thats £45 down the fucking drain.

The difference between SanDisks and Kingston is the Cylinder size.
Some cylinder sizes work well with the current SD-Card driver, some don't.

Nothing to do with speed.

time will show whether sd card speed will be an issue or not. it might be the case that it does not matter at the moment, because the sd card driver of the gp2x is not able to use the advantage of faster cards, but I am quite sure that many gp2x users will regret buying the cheap Sandisks. I tested the card in other devices as well, it is sooo slow.

 

[Mr. Anderson]

Can't be a speed issue, seriously no divx movie should be 16MBIT/sec cause that's the speed every, even the slowest SD, and for sure the sandisk ones, can deliver, 2MB/sec.

I have a 1gb Sandisk SD card and I haven't had any problems. I can flash my firmware, play high bitrate video files and load psx roms with no problem. I am happy with mine.

 

[chris_r]

I've got a 1gb sandisk card and it works perfectly fine

 

[Cellsplitter]

I'm just hoping for a FW update soon so I can use my 2GB SD card (150x ) right away

 

[mysticbeta]

Same here with my sandisk 1 gig card. It works with running psx roms.

 

[craigix]

The intergral ones are actually quite fast, 99x or 66x I think.

The new firmware supports 2gig.

 

[nickspoon]

some applications will not work

Grammar Police!

 

[Cellsplitter]

The new firmware supports 2gig.

As in allready excisting firmware? Up comming one? Enough tease
