This is a compatibility list for SD, SDHC and SDXC cards. The cards listed in '''green''' work with any file system. The cards listed in '''yellow''' work well only with one file system (this still means they can be used on the Pandora). The cards listed in '''red''' do not work well with any file system. Although it is not covered on this list, the Pandora can also read NTFS-formatted SD cards if the [http://www.open-pandora.org/downloads/CodecPack.pnd Community Codec Pack] is installed.

Note: always measure read speed by opening a terminal window and typing this command:
* the first inserted SD Card: '''dd if=/dev/mmcblk0 of=/dev/null bs=4MiB count=100'''
* the second inserted SD Card: '''dd if=/dev/mmcblk1 of=/dev/null bs=4MiB count=100'''

Note: The first inserted SD Card will always be /dev/mmcblk0, regardless if you put it into the second or first SD Card slot, whereas the second will be /dev/mmcblk1

If you can afford '''''destroying''''' all your data, you can test write speed. But be careful, you will need to create a new partition table, afterwards! You can use [http://www.gp32x.com/board/index.php?/topic/56915-gparted/ Gparted] to make new partition table.
* the first inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk0 bs=4MiB count=100'''
* the second inserted SD Card: # '''dd if=/dev/zero of=/dev/mmcblk1 bs=4MiB count=100'''

By default, the first partition starts at block 8192 (4096KB) for 32GB cards, and block 32768 (16384KB) for 64GB cards. 64GB cards may need to be [[formatting SD cards|reformatted]] before use.

<div style="background: #F3F781">Serious issues{{HideableNotes|My Linux computer can't read it, but that is probably the computer. First formatted it to ext2 while leaving 16MiB free at the beginning because it was like that when I got it. Had 16MB/s r/w. Then started to have problems after writing about 64GB to it, couldn't mount it, reformatted it, no change, reformatted it as Fat32, still no change, reformatted again as fat32, no problems so far but write speed is 0.5MB/s and read speed 14.76MB/s. I let F3 run over it, the speed was measured using it too. --A few weeks later-- It has got variable w/r speed, it drops after a few seconds of writing data to it. Sometimes it gives other errors, stops working until I reboot, etc. It's useable, but I wouldn't buy it again.}}</div>
