I was just about to install a larger C: drive on my PC which was configured as RAID0 (there are also two other HDD's for data/storage set as RAID1), then I read a thread from within this newsgroup in which Carey Frisch (Microsoft MVP) directed someone to read - Why RAID is (usually) a Terrible Idea http://www.pugetsystems.com/articles?&id=29 and that has made me re-think my plans.
Is RAID really worth? it is a much more complex setup and a nightmare when things go wrong and, as the article points out, there is a 25 - 30% chance something will go wrong. Indeed my own experience of a previous PC with RAID1 showed that it was by no means an easy task to restore everything when one HDD did fail after just 4 months.
So I'm left with a total of 4 HDD's and wondering if I should even consider RAID, OK so I do a bit of HD video editing and RAID0 'could' speed things up, but will I really notice that gain? I have equally undertaken HD video editing on a much less powerful non-RAID PC and managed OK.
The one think that RAID1 'was' in my mind (and I would suggest in the mind of many others) always useful for was data protection (but with loads of hassle) so I'm thinking there must be a way whereby I can install all four drives so that only two are visible and the other two are a mirror image set so that at the end of the day, or maybe twice a day, some software would back up the main visible drives to the 'invisible' back-up drives. Thus if any drive failed, I could just switch connectors and re-boot.
Now, is what I've said a pipe dream or can it happen, and if so what software and are there any obvious pitfalls - apart from the time to make the back-up at the end of each day?

You would be better off by placing two of the drives into external housings and using them for OS images and important data.
RAID is worth the trouble for mission critical stuff where there is an accomplished system administrator on hand to fix problems..
For the average user in an office pool or at home, RAID = bragging rights..
