Storage drive requirements for RAID levels

Your computer supports M.2 Non-Volatile Memory Express (NVMe) solid-state drive.

Note: Ensure that your computer has two identical storage drives installed (two M.2 NVMe solid-state drives with the same capacity) for supported RAID levels. If only one drive is installed, or two different types of drives are installed, the following information does not apply.

Your computer supports the following RAID levels:

RAID 0: striped disk array (missing data resulting from a drive failure cannot be reconstructed)
- Consist of two identical storage drives
- Supported strip size: 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB
- Better performance without fault tolerance
- Higher risk of data loss resulting from a member drive failure compared with non-RAID configuration
RAID 1: mirrored disk array
- Consist of two identical storage drives
- Improved reading performance and 100% redundancy
