Chapter 2. RAID Array Controller
EK–SMCPO–UG. A01 2–17
Figure 2–8 Diagram of a RAID 5 Write
RAID 5 handles drive failures in the same manner as RAID 4, except the parity
is different for each stripe. The controller either uses the parity information on a
stripe to reconstruct its data or simply reads the data as normal, depending on the
location of the stripe’s parity drive.
While RAID 5 is ideally suited for applications with many, small I/O operations,
there is no reason why it cannot function equally well for applications with large,
sequential I/O operations. This makes RAID 5 an excellent all-purpose RAID
level.
