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	14.7 MB/sec	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 MB/sec	doesn't have badblocks, seems that "Flash Translation Layer" is not suitable for ext filesystems
Kingston	1GB	unknown	Kingston 1GB (blue)	7 MB/sec	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	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.	13.8 MB/sec	very similar to that broken 32GB pretec. Except that this one almost works good.
