1. Strip of Mirros, we need minimum of4 Drives
Lets consider following example. Let say we want to write the Bayt on the raid10 so let see how it works
HDD1 HDD2 HDD3 HDD4
B B A A
Y Y T T
2. Excellent redundancy ( as blocks are mirrored)
3. Excellent performance ( as blocks are striped)
Raid10 requires a minimum of4 disks.
The total data is first stripped to two disks Disk1 & Disk2 (Raid0) ie DATA = DISK1 + Disk2
each disk which contains the stripped data will be having a mirror disk (Raid1)
ie DATA = [ (DISK1 = Disk3) + (DISK2 = Disk4) ]
Raid10 = raid0 + raid1
If any one pair ie stripped data disk (Disk1) and its mirror (Disk3) fail the entire data is lost .
Redundant Array of Independent Disks is a way of storing the same data in different places. RAID10 combines disk mirroring and disk striping to protect data.
A RAID 10 configuration requires a minimum of four disks, and stripes data across mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved. If two disks in the same mirrored pair fail, all data will be lost because there is no parity in the striped sets.
Redundant Array of Independent Disks is the way of combining several independent and relatively small disks into a single storage of a large size. The disks can be combined into the array in different ways which are known as RAID levels. Each of RAID levels has its own characteristics of:
Fault-tolerance, Performance & The capacity
RAID10, also known as RAID 1+0, combines disk mirroring and disk striping to protect data.
A RAID10 configuration requires a minimum of four disks, and stripes data across mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved. If two disks in the same mirrored pair fail, all data will be lost because there is no parity in the striped sets.
RAID10 provides redundancy and performance, and is the best option for I/O-intensive applications. One disadvantage is that only50% of the total raw capacity of the drives is usable due to mirroring.

RAID 10 is a combination of RAID 0 AND RAID 1, minium reqirement for hard drives is 4
RAID is a data storage virtualization technology that combines multiple disk drive components into a logical unit for the purposes of data redundancy or performance improvement.
RAID10 works by striping and mirroring your data across at least two disks. Mirroring, or RAID1, means writing your data to two or more disks at the same time. Even if one disk fails completely, the mirror preserves the information. Striping, or RAID0, means breaking your data up into chunks and writing the chunks to different disks in succession. It improves performance because the computer can get data off more than one disk simultaneously.
Put RAID1 and RAID0 together and you get RAID10. RAID10 is secure because mirroring duplicates all your data. It's fast because the data is striped across two or more disks, meaning chunks of data can be read and written to different disks simultaneously.
RAID 10 is the combination of mirroring and striping.
