Gateway MAN FX510 Reference Manual page 38

RAID 5 stripes both data and parity information across
multiple drives. Striping across drives improves overall
performance, and the parity information provides data
protection. Because of the error-correction capabilities, if a
drive fails, the data can be quickly and automatically fixed.
RAID 10 (also called RAID 1+0 or RAID 1&0) contains sets of
RAID 1 mirrors acting as drives within a RAID 0 striping array.
With this setup, the array could survive one drive failure in
each mirror array.

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
drives (350 GB, 300 GB, 250 GB, and 200 GB) in a RAID 10
array, your computer recognizes a single drive with 400 GB
total capacity.
