SD compatibility list
From Pandora Wiki
Note: always measure read speed with this command:
in left slot:
- dd if=/dev/mmcblk0 of=/dev/null bs=4MiB count=100
in right slot:
- dd if=/dev/mmcblk1 of=/dev/null bs=4MiB count=100
If you can DESTROY your data, you can test write speed with this:
in left slot (be careful, you will need to create a new partition table!):
- dd if=/dev/zero of=/dev/mmcblk0 bs=4MiB count=100
| SDHC card brand | Card size | Card class | Full name | URL | fat32 is working? | ext2/3/4 are working? | read speed MB/sec | write speed MB/sec | Notes |
|---|---|---|---|---|---|---|---|---|---|
| Kingston | 32GB | class 10 | class 10, kingston 32GB (red) | http://images.google.com/images?q=class+10+kingston+32GB like this, but 32GB: http://www.komputronik.pl/index.php/product/101490/Sprzet_komputerowy/Podzespoly_PC/Secure_Digital_16GB_Kingston_High_Capacity_Class_10.html | yes | no | 15.2 | 12.4 | doesn't have badblocks, seems that "Flash Translation Layer" is not suitable for ext filesystems |
| Pretec | 32GB | class 10 | class 10, Pretec 32GB 233x (white/green) | http://images.google.com/images?q=class+10+pretec+32GB+233x | yes | no | 14.1 | ? | doesn't have badblocks, seems that "Flash Translation Layer" is not suitable for ext filesystems |
| Kingston | 1GB | unknown | Kingston 1GB (blue) | looks very similar to this one, except that I have 1GB: http://www.komputronik.pl/index.php/product/26645/Sprzet_komputerowy/Podzespoly_PC/Secure_Digital_2GB_Kingston.html | yes | yes | 12.5 | ? | ok |
| Pretec | 4GB | 10 | Class 10, Pretec 4GB, 233x (white/green) | http://images.google.com/images?q=class+10+pretec+4GB+233x | yes | yes - I had very few fsck problems, and after several tries running fsck, they eventually got corrected. | 14.0 | ? | very similar to that broken 32GB pretec. Except that this one almost works good. |
