RAID
This section introduces RAID-related information.
What is 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:
• 2.5-inch form factor, 7-mm (0.28-inch) height hard disk drive
• M.2 Non-Volatile Memory Express (NVMe) solid-state drive (for selected models)
