Explore the Exciting World of RAID Technology!
What makes RAID technology such an innovative solution for data storage?
a. RAID-5 is preferred to RAID-1 when the database requires frequent data modifications.
b. RAID-1 requires more storage than RAID-5.
c. RAID-1 requires less write time than RAID-5.
d. RAID-5 does not duplicate the data items themselves.
Dive into the World of RAID Technology!
RAID (Redundant Array of Independent Disks) is a cutting-edge technology that revolutionizes data storage by utilizing multiple physical hard drives to create a single logical drive. This innovative approach offers increased storage capacity, data redundancy, and improved performance.
Delving Deeper into RAID Technology
Let's break down each statement to gain a better understanding:
a. RAID-5 is preferred to RAID-1 when the database requires frequent data modifications. This statement is accurate because RAID-5 strikes a balance between read and write performance, making it ideal for scenarios involving frequent data modifications.
b. RAID-1 requires more storage than RAID-5. This statement is also true. RAID-1 involves mirroring data, which necessitates double the storage space compared to RAID-5, which leverages parity information and requires less storage.
c. RAID-1 requires less write time than RAID-5. This statement is correct as well. RAID-1 boasts faster write times since it only needs to write data to two drives, whereas RAID-5 must handle both data and parity information.
d. RAID-5 does not duplicate the data items themselves. This statement is actually incorrect. Although RAID-5 doesn't mirror data like RAID-1, it provides redundancy through parity information, enabling data recovery in case of drive failure.
In conclusion, statement d is the incorrect one about RAID technology. RAID-5 does deliver redundancy and supports data recovery through the utilization of parity information, even though it doesn't directly duplicate data items themselves.
