Hi, dear!

Welcome to our community!

RAID 1E is an enhanced version of RAID 1. It is a private RAID level proposed by IBM and has not become an international standard. It is not a combination of RAID 0+1. The working principle of RAID 1E is basically the same as that of RAID 1. The only difference is that RAID 1E has a stronger data recovery capability. However, RAID 1E writes data at least twice, which increases the load of the RAID processor and reduces the disk read/write capability. RAID 1E requires at least three hard disks.

For details, see https://forum.huawei.com/enterprise/en/raid-1e/thread/632099-887

Best wishes!

Hi,

RAID1E is a combination of RAID 0 and RAID 1. Strong point is that it has higher data recovery but as it writes data twice, it puts load on RAID processor and also higher storage is required.

Also note that it is NOT INDUSTRY STANDARD as of now.
