Hello NinjaNife,
The Number of drives supported depends on different factors such as:
1. Disk technology. SATA tolerates smaller arrays than SAS/FC does.
2. RAID Controller processor.
3. RAID Controller.
4. Bus bandwidth.
5. Etcetera.
A RAID 10 array uses four hard drives to create a combination of RAID levels 0 and 1.
It is a striped set whose members are each a mirrored set.
In this particular case you may need to use Matrix RAID which allows you to create two RAID volumes on a single RAID array by using the RAID migration feature which enables a properly configured PC, known as a RAID-Ready system, to be converted into a high-performance RAID 0, RAID 1, RAID 5, or RAID 10
configuration by adding one or more Serial ATA hard drives to the system and invoking the RAID migration process from within Windows.
The following RAID migrations are supported:
• RAID-Ready to 2,3,4,5 or 6-drive RAID 0.
• RAID-Ready to 2-drive RAID 1.
• RAID-Ready to 3,4,5 or 6-drive RAID 5.
• RAID-Ready to 4-drive RAID 10.
The migrations do not require re-installation of the operating system. All applications and data remain intact.

Note: All migrations may not be available as each migration is supported on specific platform configurations.
