RAID 10
RAID 10 combines the protection of RAID 1 with the performance of RAID 0. Consider a volume with four hard
drives. RAID 10 creates two RAID 1 segments, and then combines them into a RAID 0 stripe. With eight hard
drives, the RAID 0 stripe will include four RAID 1 segments. Such configurations offer exceptional data
protection, allowing for two hard drives to fail across two RAID 1 segments. Additionally, RAID 10 writes data
at the file level and, due to the RAID 0 stripe, gives users higher performance when managing greater amounts
( . of smaller files. This means a more generous input/output per second for data (IOPS
RAID 10 is a great choice for database managers that need to read and write many small files across the
volume. The impressive IOPS and data protection offered by RAID 10 gives database managers impressive
.reliability both in keeping files safe and rapid access
RAID 1+Spare(s), RAID 5+Spare(s), RAID 6+Spare, and RAID
10+Spare
