Are two drives better than one?

[Conan]

From Anandtech (http://www.anandtech.com/index.html):

Western Digital's Raptors in RAID-0: Are two drives better than one? (http://www.anandtech.com/storage/showdoc.html?i=2101&p=1)

Bottom line:


If you haven't gotten the hint by now, we'll spell it out for you: there is no place, and no need for a RAID-0 array on a desktop computer. The real world performance increases are negligible at best and the reduction in reliability, thanks to a halving of the mean time between failure, makes RAID-0 far from worth it on the desktop.

So really it is more like

"are 2 better than one?"

"Yes but you won't notice"

Hmm - I felt a real world performance increase - or maybe it was just placebo???
The article is heavily biased on 2 main benchmarks. Also, RAID doesn't have to be so expensive. The article suggests getting 2x100GB. Who needs that much space? I have 2x60GB. RAID 0 is quite safe if you take regular images (Ghosting) on to a third drive. I just use the drive on my old PC.
