From 2nd year stats (and subject to the ravages of time on my memory): a
display array of 10x20 1000hour lamps will have a lamp fail on average every
20 min !!
According to Seagate the failure rate of 2 disks is much greater than 2x
failure rate of 1 disk http://portal.acm.org/citation.cfm?id=1090724
Along with all the cute benefits that LVM offer is a much higher disk failure
rate. Is the windows-linux convert going to pay attention to needed backup
regime?
I don't believe it is in the best interest of this user to do kewl rad stuff!
