He's talking about software RAID there, not hardware btw.
Some claim that in certain circumstances that software RAID is better than hardware, though YMMV.
The general concensus from the groupp is that sw-raid is useful, a Good Thing, and ready for production environments - indeed many of them use it At Work.
If you're really interested in software RAID, go join the linux-raid mailing list, it's a good bunch of people, with a mix of setup,installation, in-production and technical talk.
Funnily enough the latest RAID code is still in 'alpha', even though there is a (unused, unreccomended and older) 'beta' version. There's also a minor contre-temps between the raid group and Linus as to exactly when raid will ship in the kernel, similar ro the ISDN spat.
The article pretty much covered most stuff, though you may want to check out the RAID FAQ - though ignore the one on linux.org/linuxdoc.org - it is hopelessly out of date. Check via the mailing list for the real one.
