VFSBench results

This page is no longer being updated. Please don't send me new values. (Who runs palm os anymore anyway?)

I'm leaving this page online in case someone find old data like this interesting.

These benchmark values have been generated with VFSBench, VFS volume benchmark for PalmOS devices.

The results themselves have been reported by several people. Due to the inaccuracy of any benchmarking process, these values should only be taken as a guideline. It's still surprising that different cards are orders of magnitude faster than others.

The benchmark itself generates one 1MB file, and writes data to it in 4KB blocks, timing the result. As a benchmark, actual usage of a card (or any other media) may yield different results.

Please note, that if you run the benchmark (which you'll be doing at your own risk), the benchmark will take some time to run. Especially with the cards that have a write speed of less than 1MBps the benchmark may take surprisingly long time to finish.

It used to be possible to add to this list, by reporting your scores by emailing me. Any results, even slower than ones on the list, were accepted. I was especially interested in results generated with other PalmOS devices than the Zodiac.
