WebDec 9, 2024 · RAID is mainly designed for higher read/write speed and improved data redundancy, or both—over the traditional hard drive storage. There are different RAID levels, such as RAID 0, 1, 5, 10, and more. The first step in setting up RAID on your home server is choosing a suitable RAID level. WebApr 14, 2024 · RAID 10 – Mirrored Striping. RAID 10 combines the redundancy of RAID 1 with the performance of RAID 0. It involves striping data across two sets of mirrored drives. RAID 10 provides an excellent read/write performance and has a fault tolerance. RAID 10 is suitable for large systems requiring high data availability and high performance.

"RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks. This configuration offers no parity, striping, or spanning of disk space across multiple disks, since the data is mirrored on all disks belonging to the array, and the array can only be as big as the smallest member disk. This layout is useful when read performan… " - Read write performance raid levels
