RAID
Redundant Array of Independent Disks (RAID) is a technology that provides increased storage functions and
reliability through redundancy. It also can improve data storage reliability and fault tolerance compared with
single-drive storage systems. Data loss resulting from a drive failure can be prevented by reconstructing
missing data from the remaining drives.
When a group of independent physical storage drives is set up to use RAID technology, they are in a RAID
array. This array distributes data across multiple storage drives, but the array appears to the host computer
as one single storage unit. Creating and using RAID arrays provides high performance, such as the expedited
I/O performance, because several drives can be accessed simultaneously.
Storage drive requirements for RAID levels
Your computer supports the following internal storage drives:
• 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

dialog asks for confirmation to clean up the storage. If you select “Yes”, all data
that were created by the operating system or programs will be deleted except
global variables defined by the Unified Extensible Firmware Interface
Specification. If you select “No”, all data will be kept, but the operating system or

If this error happens at a service center, Lenovo authorized service personnel will
clean up the non-volatile system UEFI variable storage using the preceding
solution.
