What RAID configuration option is available for a server with two drives?

RAID 0 is indeed the correct answer when considering a server with only two drives. This RAID configuration uses both drives to create a single larger volume that benefits from increased performance through striping, meaning that the data is split into blocks and written across both drives simultaneously. This approach not only enhances read and write speeds but also maximizes storage utilization since the combined capacity of both drives is available for use.

RAID 5 and RAID 6 require a minimum of three and four drives, respectively, due to their need for parity data for fault tolerance. RAID 10, which combines RAID 1 and RAID 0, also requires at least four drives as it provides both mirroring and striping. Therefore, RAID 0 stands out as the most suitable option for servers with just two drives, offering both simplicity and high performance, albeit without any redundancy.
