Since the Operating System has not been specified i'm assuming you are talking about Windows OS. RAID10 is not available as a software RAID level. To be honest you really should be using hardware instead anyways
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.
Before we go one, here's one important caveat about backup and RAID1. Although data is written to two disks simultaneously, the data is not being backed up. Should your system rather than the hard disk suffer an error, erroneous data could be sent to both disks at the same time, corrupting both drives simultaneously. You still must have a backup strategy in place, even if you use RAID1.
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.
As Mohit Kumar Srivastava said RAID10 is not available as a software RAID level in WIndows OS. Its only support Linux Systems
