RAID 0 - Striping:
It is the Stripped Disk Array with no fault tolerance and it
requires at least 2 drives to be implemented. Due to no
redundancy feature, RAID 0 is considered to be the lowest
ranked RAID level. Striped data mapping technique is
implemented for high performance at low cost. The I/O
performance is also improved as it is loaded across many
channels. Regeneration, Rebuilding and functional redundancy
are some salient features of RAID 0.
RAID 1 - Mirroring:
It is the Mirroring (Shadowing) Array meant to provide high
performance. RAID 1 controller is able to perform 2 separate
parallel reads or writes per mirrored pair. It also requires
at least 2 drives to implement a non-redundant disk array.
High level of availability, access and reliability can be
achieved by entry-level RAID 1 array. With full redundancy
feature available, need of readability is almost negligible.
Controller configurations and storage subsystem design is
the easiest and simplest amongst all RAID levels.
RAID 5:
RAIDS 5 is Independent Distributed parity block of data
disks with a minimum requirement of at least 3 drives to be
implemented and N-1 array capacity. It helps in reducing the
write inherence found in RAID 4. RAID 5 array offers highest
data transaction Read rate, medium data transaction Write
rate and good cumulative transfer rate.
