However, it has superior fault tolerance and rebuild performance. Minimum number of drives required: 4. Performance RAID 10 provides the high efficiency of RAID 0 and the safety of RAID 1. Just like in RAID 0, the read and write speeds will be incredibly fast, although the storage space will be cut in half, as is typical with a RAID 1 configuration. This array is less likely to cause permanent data loss.

Det går att nästla (kombinera) olika Raid-nivåer. Raid 1+0 (kallas även Raid 10) speglar först två hårddiskar (Raid 1) och slår sedan samman dem med två andra (Raid 0). Det går även att först slå samman ett antal hårddiskar och sedan spegla dem (Raid 0+1). RAID 01, also called RAID 0+1, is a RAID level using a mirror of stripes, achieving both replication and sharing of data between disks. The usable capacity of a RAID 01 array is the same as in a RAID 1 array made of the same drives, in which one half of the drives is used to mirror the other half.

A great many people take the disk performance into the first consideration when choosing RAID 0 or RAID 1 array. In raid 0+1 the first disk failure fails all disks in that stripe, the failure of any subsequent disk means a member of the other stripe has failed and so data access is lost. Two disk failures = total data access losss.

What is RAID? RAID 0, 1, 5, & 10 Made Easy - The Plug

My PC came from Dell with 2 250GB hard drives configured for RAID 1(Mirroring). I have since bought an external harddrive for backup and now would rather have my drives configured for RAID 0(striping) for the extra hard drive space and performance. 2009-08-12 Raid 0+1 vs Raid 1+0 (Probability of Failure) Here's a little bit of math that should show the differences in rates of failure. For simplicity, let's assume there is an even number of disks.

This is a “best of both worlds approach”, because it has the fast performance of RAID 0 and the redundancy of RAID 1. RAID 10 combines the mirroring of RAID 1 with the striping of RAID 0. Or in other words, it combines the redundancy of RAID 1 with the increased performance of RAID 0. It is best suitable for environments where both high performance and security is required.

And hence you get qualities of both the raid levels. Lets understand how data is stored in raid 10 array. If you see the above diagram data is redundant with DNS-343-4TB 4TB ShareCenter 4-Bay Network Storage, SATA, RAID 0/1/5, JBOD, USB Print Server. $899.99 RAID 10 (Redundant Array of Independent Disks Mode 10) A RAID subsystem that increases safety by writing the same data on two drives (mirroring), while increasing speed by interleaving data across two or more mirrored "virtual" drives (striping).RAID 10 provides the most security and speed but uses more drives than the more common RAID 5 method.
