[Techtalk] Made RAID Mistake?

[Andrew]

	The nugget posted by Kelly is great for giving prospective to nubies like 
myself.  Thank you. 
	I read a theory piece that questioned the need for hardware Raid now that 
100,133 and SCSI 160MHz are available on the board or with less expensive 
non-raid cards. Using intelligent partitioning, LVM and maybe software raid 
should give satisfactory results. 
	I am interested in opinions of the experienced people here. Maybe I am 
missing part of the concept?
