Format Program test:

When I formatted the 16 G original Class 2 with all three programs (Windows, SD Format and WinMo), H2testw v1.4 came up with the same basic read and write speeds for all three at 512/64. The only difference that I see is the WinMo

only makes one copy of the FAT and the others make two. Single FAT is supposed to be faster in the real world according to the tech literature because it only has to write the FAT once. This fact only really shows up when the disk becomes fragmented according to the Xperts.

Methodology: This test was about as scientific as making Kool Aid, but I did start with freshly formated SD cards that I then copied the same exact file system on, so they were about as de-fragmented as possible. At least they were all the same. I had to delete some movies/music etc. from the small card so the SD Card test could run. It needs 300 mb of clean space. Test does not use those files anyway. Testing cards with H2testw v1.4 after format and after files were copied on them gave exactly the same read'write speeds basically.

Conclusion: I will run some more tests (see if 512/64 format helps the 4G Class 2 and format one card with all 3 programs and test all benchmarks), and graph the results before opening my big mouth about what I think all this means.
