I got my Kingston 512MB SD card and I ran the Pocket Mechanic Benchmark utility on them. Here are the results:
----------------------------SanDisk 256MB-------Kingston 512MB
Read Speed:----------.11 MB/Sec-----------.37 MB/Sec
Write Speed:----------.02 MB/Sec-----------.14 MB/Sec
Min Read time:--------.25ms-----------------.25ms
Max Read Time:-------11.25ms--------------15.25ms
Avg read time:---------4.63ms---------------1.31ms
Sectors/block:---------variable 0-64--------variable 0-64
Min. write time:--------1.00ms---------------1.00ms
Max Write time:-------33.00ms--------------34.50ms
Avg write time: --------28.61ms-------------3.44ms
Read write ratio:------.16--------------------.38
Sector size:-------------512 bytes-----------512 bytes
The Kingston kills the Sandisk in Avg Write Time but the Sandisk is slightly better in Avg read time. I think, if I'm reading it correctly ...the Read and Write speed is clearly in favor of the Kingston...
