im not arguing against backups or raid. just that the un-necessary use
of a closed on-disk format. making any chance of a different hardware
raid system unable to read a disk. There are situations when you dont
have a 100% accurate backup (maybe for 1hr of the day at most if your
boss actually lets you backup to tape on a good schedule) the closed
hardware raid card formats make any chance of data salvage in this case
almost impossible, whereas a software raid system doesnt.
