What is parity in RAID and how does it work?
Parity in RAID is a method used to provide fault tolerance by storing parity information, which allows data recovery.
Can you explain how parity is calculated in RAID?
Sure! Parity is calculated by performing a bitwise XOR operation on the data blocks. This creates a parity block that can be used to reconstruct lost data.
What are the advantages of using parity in RAID?
The main advantages include data redundancy, improved read performance, and the ability to recover from a single drive failure.
Are there any downsides to using parity in RAID?
Yes, the downsides include slower write performance due to the need to calculate and write parity data, and the risk of data loss during rebuilds.
