Using RAID-1 mirroring of two partitions on a single drive doesn't make a lot of sense: it will greatly slow down performance without gaining any real improvement to reliability. What blocksize you should use depends somewhat upon the files you use, and is best determined by benchmarking your expected load using the data you have; that said, normally a small blocksize will work fine if you have lots of small files. -- -Chuck
