"RAID", whether "cheap'n'cheerful" or not, whether "software" or not -- but on ONE AND THE SAME PHYSICAL DRIVE?!? Yes, that certainly sounds like an idea so great that ONLY Microsoft could have come up with it. DON'T "Just Say No". SCREAM Nooooooo! [link\|mailto:MyUserId@MyISP.CountryCode\|Christian R.

Your 'depression' may be the closest you ever come to recognizing truth: you have no 'inferiority complex', you are inferior - and something inside you recognizes this. - [link\|http://z.iwethey.org/forums/render/content/show?contentid=71575\|Ashton Brown]

As opposed to the case with a "cheap'n'cheerful software RAID" array consisting of separate partitions (be they ordinary partitions, or "Windows Dynamic" ones) of the same physical drive, where there isn't even a theoretical chance of an improvement. RAID-ing parts of the same actual disk hardware is an oxymoron, a symptom of a deep misunderstandidng (which this iMac tinkerer did not labour under) of the whole idea: However many partitions you split a disk up into, you've still only got the same number of heads and platters that you started with.

Of course writing is a lot slower.
