Re: Software RAID and drive failures

[Calyth <calyth@shaw.ca>]

I'm no expert comparing to the other people here who've experimented the 
whole thing out, but I'd think that you might want to get at least 3 IDE 
drives and set up RAID 5 instead.
Say you got 3 20GB HDs, RAID 1 (mirroring) would only give you 20GB of 
space, while RAID 5 would provide more, yet still be able to make sure 
that if one of the drive fails, you can still run with the data on the 
other two drives and not be missing anything. I'm fairly sure that most 
high end server at least uses some form of RAID 5 because of its advantages.
Others already raised a good point. Does data integrity means no 
downtime or no data loss. If they meant no downtime, then your task is 
much, much harder.
Good luck! =)
