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 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 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 reformatted before use.

Card size in GB Card class Full name URL fat32 is working? ext2/3/4 are working? read speed MB/sec write speed MB/sec actual capacity (1024byte blocks) Notes
32 10 Centon 32GB Class 10 SDHC [1] yes ? 17.3 23.9 ? ok so far, first few hours of use
1 n/a Kingston 1GB (blue) [2] yes yes 12.5 ? 1006080 ok
8 4 Kingston 8GB Class 4 (black) not long-term tested yet not long-term tested yet 17.1 4.8 ? From Craig's shop, so must be ok ;)
16 4 Kingston 16 GB Class 4 SDHC [3] no no 15 9.5 15663104 Bad controller chip, fails in the same manner as the 32GB card.
32 4 Kingston 32 GB Class 4 SDHC [4] no no 16 9.5 31539200 Defective flash controller randomly loses writes regardless of filesystem. When attempting to write, blocks sometimes get erased but not written.
32 10 Kingston 32GB (red) Class 10 [5] yes no 15.2 ? ? doesn't have badblocks, seems that "Flash Translation Layer" is not suitable for ext filesystems
32 4 Lexar Multi-Use 32GB [6] yes yes 16.1 14.4 31267840 Much faster than would be expected for a class 4 card. Usual warning about high-speed cards being susceptible to power supply glitches applies.
32 10 Lexar Premium Series 32GB 100x [7] yes no 16.7 12.0 ? Worst ext2 support ever. Copying fine, a LOT of I/O errors at first boot. Literally unusable. Fat32 seems perfectly supported.
64 10 Lexar Professional 64GB 133x [8] yes yes 19.6 15.1 62536704 R/W speed in the pandora is limited to 16.1/11.3 MB/sec. High power consumption, may fail under load.[9]
128 10 Lexar Professional 128GB 133x SDXC [10] yes yes 17.2 11.8 122.97GiB Speeds listed are IN a Pandora.[11]
16 6 Maxflash 16GB Class 6 SDHC [12] ? yes 14.4 ? 16186368 Works fine
8 6 Panasonic SDHC 8GB (RP-SDQ08G) [13] yes ? 16.0-17.2 12.1-13.1 7778304 seems to work fine. Ext yet untested.
32 10 Patriot LX 32GB SDHC Class 10 (PSF32GSDHC10) [14] [15] yes no/yes 18.1 12.6 ? Formatting EXT2 and then running fsck right after finds errors. Seems to work well with fat32 /// Entry 2 from another user: Works great with ext2. No errors or issues.
4 10 Pretec 4GB, Class 10, 233x (white/green) [16] yes yes (mostly) 14.0 ? 3883008 I had very few fsck problems, and after several tries running fsck, they eventually got corrected. It looks very similar to that broken 32GB pretec. Except that this one almost works good.
32 10 Pretec 32GB Class 10, 233x (white/green) [17] yes no 14.1 12.4 ? doesn't have badblocks, seems that "Flash Translation Layer" is not suitable for ext filesystems
32 10 PNY 32GB (P-SDHC32G10) [18] yes ? 17.1 ? ? Works fine. EXT untested.
16 6 Samsung 16GB SDHC [19] yes ? ?? ?? ?? seems to work fine. Ext yet untested.
32 10 Samsung 32GB MicroSDHC Class 10 (MB-MSBGA) [20] yes yes 18.1 11.7 30657536 Works. Claimed to be resistant to magnets, shocks, and seawater—as if you’d be able to find it in the ocean!
64 10 SanDisk SDXC I 64GB Ultra 30MB/s Edition [21] yes ? 17.5 9.4 ? SDSDU-064G-U46
8 10 SanDisk SDHC 8GB Extreme 30MB/s Edition [22] yes yes 16.6 ? ? Works nice. Installed Angstrom on it and copied some stuff onto it. Angstrom runs as fast as from NAND. Best thing was, where I ordered it it said class 6, but it is actually 10. :-D Still have to test its speed and actual size. Didn't test Fat a lot, but it seemed to work.
8 10 - UHS 1 SanDisk Extreme HD Video SDHC UHS-I 8GB 30MB/s 200X [23] yes yes 16.6 15 ? Works.

? After some time the system gives read/write errors. Works fine on a pc with linux with ext2/ext3.
Serious issues. 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.
32 6 Verbatim Class 6 Premium HD Video 32GB SDHC [37] no no ? ? ? Behaviour similar to Kingston 32GB Class 4 -[38]
32 4 Zap Glider 32GB Class 4 [39] ? yes 16.6 4.6 ? Works fine
