SD card comparative speeds
I have some 'Kingston Elite Pro 50x' 2GB SD cards and am struggling to
get a definitive answer on whether they are faster or slower than SDHC Class 6 cards. Anyone care to offer an opinion? I've not been able to get a clear answer from Kingston. -- F |

I've not been able to get a clear answer from Kingston. See http://en.wikipedia.org/wiki/Secure_Digital Class 6 is the new name of 40x. The class number of more less the data write rate in Mbytes/sec, whereas the NNx designation refers to the old 150KBytes/sec used for CD-ROM drives. -- Bertrand |

It cleared up a lot of ambiguities I had about Read / Write Speeds and Class vs nnnX Speeds. Bob Williams |
