If you can DESTROY your data, you can test write speed with this: in left slot (be careful!):

SDHC card brand	Card size	Card class	Full name	URL	fat32 is working?	ext2/3/4 are working?	read 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	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.
