Question

you are building a new computer that will contain two hard disks. to provide increased performance, you have decided to configure the drives using raid technology.
which of the following will best meet your needs?
raid 1
raid 2
raid 0
raid 5

Explanation:

• RAID 1 is mirroring, prioritizing data redundancy over performance, no speed gain.
• RAID 2 uses bit-level striping with dedicated parity, not focused on raw performance and rarely used today.
• RAID 0 uses disk striping across drives, which splits data across both disks to read/write simultaneously, directly boosting performance (no parity overhead, uses full storage capacity of both drives for speed).
• RAID 5 requires at least 3 disks for distributed parity, so it can't be used with only 2 drives.

Answer:

RAID 0
