I stayed out of the last fight over RAID. I have no great love for it, and
have had more than one oops with RAID, but I also know that lots of folks
especially those in IT desire it. Apparently it's not just those using
Reiserfs who suddenly find that an Array has to be rebuilt or that something
actually appears not to have been written when it should have been. I don't
use RAID at home, instead relying on backups on external drives which I
occasionally test by taking a blank drive and seeing if I can restore
everything on that drive. Being semi-paranoid, I also regularly back up data
and pictures on DVDs. So far I haven't lost anything with this going on but I
know that eventually something will go wrong.
I have used RAID for several years. When I used a JBOD system, I always
had problems with backing up data. I did have a tape backup unit in the
system. But, I have always found tape backup problematic. I had a
250MB TB unit. But, The tapes were hard to obtain. Now, I have a bunch
of unused 200-400GB tapes which, I can't use. Since they are for the
IBM LTO2 Tape Drive and, that drive alone, is over $1,000.
So, For me, RAID is here to stay.
