hey, trying to get RANDOM ACCESS Ratings for:Topram 4Gb Micro SDHC Card Class 4
Sandisk 6GB Micro SDHC Card Class 4anyone know?checked with topram - they were helpful, had every number except the random access ratethanks

no one testing access speeds in the mircoSDHC cards then ?discovered Topram 4GB is 1ms using HD Tach
Sandisk 6gb is between 1-1.2ms i thinki dont know the Sandisk 4gb class 4, kingston 4gb or the Integral 4gb class 4anyone ?

R4DS is only compatible up to 4 GB is it not?

no, 2GB at this time.
