Question
A data analyst has asked a technician to help protect locally stored data by installing a RAID. What is the minimum number of drives the technician has to install if configuring a RAID level 10?4165
Solution
The minimum number of drives needed to configure a RAID level 10 is 4.
Here's why:
RAID 10, also known as RAID 1+0, is a combination of RAID 1 and RAID 0.
RAID 1 is a mirroring technique where data is duplicated on two drives. This means that at least two drives are needed for RAID 1.
RAID 0 is a striping technique where data is split across at least two drives. This means that at least two drives are needed for RAID 0.
Since RAID 10 is a combination of RAID 1 and RAID 0, it requires a minimum of four drives. Two drives are used for mirroring and two drives are used for striping.
