User has been concerning about how to increase partition size all the time. RAID disk array is employed to improve disk access speed among which raid 5, constituted by several hard disks, is the most popular one. Will the disk data be damaged if user increases the size of raid 5 and how could user increase partition size while insuring the data safety. To answer these questions, user should first come to understand what is raid 5.
RAID, an acronym for Redundant Array of Independent Disks is a technology
that provides increased storage reliability through redundancy, combining
multiple relatively low-cost, less-reliable disk drives components into a
logical unit where all drives in the array are interdependent. This concept was
first defined by David A. Patterson, Garth A. Gibson, and Randy Katz at the
University of California, Berkeley in 1987 as Redundant Arrays of Inexpensive
Disks. Marketers representing industry RAID manufacturers later attempted to
reinvent the term to describe a redundant array of independent disks as a means
of dissociating a low-cost expectation from RAID technology. RAID 5 distributes
parity along with the data and requires all drives but one to be present to
operate; drive failure requires replacement, but the array is not destroyed by a
single drive failure. Upon drive failure, any subsequent reads can be calculated
from the distributed parity such that the drive failure is masked from the end
user. The array will have data loss in the event of a second drive failure and
is vulnerable until the data that was on the failed drive is rebuilt onto a
replacement drive. A single drive failure in the set will result in reduced
performance of the entire set until the failed drive has been replaced and
How to increase raid 5 size?
It is tough
to perform operations on raid 5 partition, since many third-party partition
managers don't cover functions of performing operations on raid 5. Fortunately,
MiniTool Partition Wizard, an excellent partition manager is available for user
to realize such operations such as extend partition, wipe partition, resize partition, merge partition, create partition, delete partition, format partition, convert partition format, copy partition, hide partition, explore partition, change drive letter, etc. Still, user
could employ MiniTool Partition Wizard to eliminate unwanted data permanently
from be recovered with the wipe partition function.

is the demonstration is performed on basic disk partition which is still
suitable for raid 5 partition. User could obtain the same effect after
performing same operation over raid 5 partition without data loss.
