Do Raid 10 have the minimum of 6 harddrives? Or how many harddrive is the minimum required? And also is the "HP iPax 4700 PDA" a good PDA?

Four is minimum, but more is better in multiples of two.

I have never used an HP iPAC but Reseller Ratings gives it four out of five stars. I am not a fan of Pocket PCs I think they are power hungry and unless you have them plugged in to a power outlet they are just about worthless. I have a Dell x50 (4.5 stars out of 5 on reseller ratings) and it has cured me of ever buying another one, of any brand. At least until I can get 10 hours of battery life. Which would last me most days.

Raid 10 requires a minimum of 4 drives.

You'll want to make sure in an enterprise-type enviornment that your storage system assigns the pairs the way you want them. Some systems do the pairing across the drive enclosure (horizontally) and others do it across buses (vertically). What I've found is that some storage systems are dumb and you need to do it command-line (isn't too hard) to make sure it's done right.

You'll want to make sure that you pair your drives in a way to tolerate any failures....ideally across separate buses -- meaning different eclosures.

Cheers!
