Raid 1 or Raid 1+0 for SQL Server Architecture
RAID level 10(1+0) has been recommended by microsoft for high reads. Refer the doc: https://docs.microsoft.com/en-us/previous-versions/sql/sql-server-2008-r2/ms190764%28v%3dsql.105%29

This level is also known as mirroring with striping. RAID 10 uses a striped array of disks that are then mirrored to another identical set of striped disks. For example, a striped array can be created by using five disks. The striped array of disks is then mirrored using another set of five striped disks. RAID 10 provides the performance benefits of disk striping with the disk redundancy of mirroring. RAID 10 provides the highest read-and-write performance of any one of the other RAID levels, but at the expense of using two times as many disks.

RAID levels higher than 10 (1 + 0) may offer additional fault tolerance or performance enhancements. These levels generally are proprietary systems. For more information about these types of RAID systems, contact the hardware vendor.
