raid5 loop-aes

Hi everybody

I'm trying to set up an ext3 fs over loop-aes over RAID5...

I have done several benchmarks...

"hdparm -tT" over the loop device show the best results with a 64Kb chunksize

then i try different stride size for ext3 filesystem.... I tryed with 1, 2, 4, 8, 16, 32, and 64 and no stride parameters.

I found that I get the best result with no stride parameter....

I suppose that stride parameter is only useful when the fs is directly over RAID and not over a loop device. is this true?

Regards
