You can't really RAID an IDE set.
You need a SCSI subsystem which is where the "every hard disk uses its own
controller" sentence comes in.
The optimal for Exchange is hardware raid with the following configuration:
2 drives in RAID1 for the operating system.
2 drives in RAID1 for the Exchange logs.
3 or more drives in RAID5 for the exchange stores.
The RAID1 number of drives can be reduced from two individual RAID1 sets to
a pair of drives in RAID1 with two partitions.
If you have to use IDE then you might do it this way:
Controller 0 Primary - Operating System
Controller 0 Slave - Exchange Install and Logs
Controller 1 Primary - Mirrored stores
Controller 1 Slave - Mirrored stores
There are several options, all of which give varying degrees of
resilience/performance mixes.

I am a new in IT World and have a stupid question , I've ever post this
message but never get an answer. I want to build Exchange Server. and I plan
to use several HD (I use all IDE both primary and secondary) , they say I
could improve performance by using RAID0 or RAID5 because every harddisk use
its own controller. Can I use that ? or anyone have an idea ?
and sometimes I confuse about harddisk contoller. a friend told me that it's
on the harddisk ( PCB attached to Harddisk) but someone else told me that
it's on the motherboard or separate card.
I don't know which one is correct .
