Sd-card Speed?

[Ethan]

Hi

as i just searched for some good sds for the pandora
i found that there might be huge differences in writing / reading speed and durability.

so if one uses a sd as harddrive, just like pandora aims to do, would a cheap sd be a bottleneck for performance?

do i have performance boosts if i use f.ex. a sandisc extreme IV or another expensive (well at least higher performance) sd?

greetings

The SD Speed Class Ratings specify the following minimum write speeds based on “the best fragmented state where no memory unit is occupied”:

Class 2: 2 MB/s
Class 4: 4 MB/s
Class 6: 6 MB/s

We'll soon find out whether or not it's worth getting one over the other, my guess is it probably will be if you're bothered about loading times. All will be fine though for gaming, video watching etc.

some Class 6 can go mutch fast than 6MB/s like the Panasonic SDHC 4 Go Class 6 (17MB/s read and 13MB/s write for large files)

Not cheap, but hopefully fast
