Is software raid through windows xp better than hardware raid???how to create software raid in windows xp and linux (fedora core 1/2)??? is there any prformance increase whencompared to simple HDD's performance??? one more question in nforce3/4 mobo one can combine a PATA HDD and a SATA HDD in RAID array. I did the same by taking out my old pc's PATA HDD which had 40GB space and my SATA HDD has 120GB space. but when i combined them in raid 0 (ie stripping mode) the raid array's space reduced to 80GB.why this happened???
