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 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.

  • in left slot: # dd if=/dev/zero of=/dev/mmcblk0 bs=4MiB count=100
  • in right slot: # dd if=/dev/zero of=/dev/mmcblk1 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 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 ? doesn't have badblocks, seems that "Flash Translation Layer" is not suitable for ext filesystems

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 ? It looks very similar to that broken 32GB pretec. Except that this one almost works good.
Transcend 64GB 10 Transcend SDXC Card 64GB ULTIMATE CLASS 10 (PN:TS64GSDXC10) http://www.transcendusa.com/Products/ModDetail.asp?ModNo=286&LangNo=0&Func1No=1&Func2No=13 yes (needs more testing) no 16.1 16.1 After some time the system gives read/write errors.
