Which of my 4gb Micro SD/HC cards is the best? Transcend (6) or PNY (4)

Found 8th Dec 2009
I just bought a PNY Micro SD/HC card but just found out I've already got a Transcend one in my phone that I wont be needing soon. The only difference I can see is the Transcend has a 6 on it (It was bought last year) while the PNY has a 4. They are both 4gb and I'm thinking of sending the PNY back as I don't need 2 cards. I would have thought the PNY would be better as its newer but not sure what the numbers 4 and 6 mean.
Can anybody help please?


the 6 is better
it means class 6 which is a faster card.

SD Cards and SDHC Cards have Speed Class Ratings defined by the SD Association. The SD Speed Class Ratings specify the following minimum write speeds based on "the best fragmented state where no memory unit is occupied":[8]

Class 2: 2 MByte/s - 13x
Class 4: 4 MByte/s - 26x
Class 6: 6 MByte/s - 40x

Ok thanks guys. So it looks like I'd be better off sending the 4 back then.
Thanks for your help.
