Minimum Speed For Sd Cards?

[Hodr]

I am planning to purchase a GP2X as soon as I can, but before it gets to me I need to know what type of SD card to get. I have found some very reasonable prices for slower speed units (5mbs range) and would rather buy one of those if I dont need the 20+mb/sec units that cost a hefty premium.

Basically I don't care how long It takes to write to the card from my computer, I just need to know if the read speed of 5mb/s will hinder the performance of apps or movies running on the unit itself.

I did look through the forums as best I could for the answer but never saw it addressed, and you cant search for SD because two characters are too small.

Thanks in advance for any response.

Speed of the SD card does not matter to the GP2x. If I recall correctly, the GP2x does not even use the speed of newer cards, and many of the very new cards have compatability issues with the GP2x. I read something about it running in "1 bit mode" or something, which means really slow. If anything, the GP2x will be the bottleneck for transfer speed, not the Secure Digital card (in current revisions of firmware, newer/third party ones shoud support faster transfer). I have a 40x card (medium-low speed compared to some of the newer ones), and it runs movies and games just fine. The movie player's limit is 1.5mb/s data anyways, so you will likely run into processing limits before you run into data bandwidth bottlenecks.

Edit: The most important thing to look for is compatability. The firmware updater is having issues updating off of some brands of SD cards. I think there is a sticky somewhare that talks about SD card compatability.

I saw mention in the thread about SD cards being used for bios updates that the Kingston 1gb card I plan to purchase does not work. I am hoping this is just a filesystem / formatting problem as the card itself is extremely reasonably priced at the momment ($35) and doesn't seem to have any issues as far as reliability of the card itself.

guessing my 150x card is overkill then hehe

Where can you get it for $35? I might be interested in getting another one...

hope the SD 1gb that comes with it be able to update the firmware
