Preparing Your Computer For Raid; Configuring Raid - Gateway FX6800 Reference Manual

Drawback
A RAID 5 array is treated as one drive with the capacity of all
but one of the drives added together.
RAID 10 treats the entire array as a single drive with the
storage capacity of the smallest drive × 2. So if you have four
