What is RAID Level 1?
RAID level 1 (mirroring) volume layout offers the following: Groups two or more disks as one virtual disk with the capacity of a single disk. Data is replicated on each disk, providing data redundancy. When a disk fails, the virtual disk still works. The data is read from the surviving disk(s).
How do I increase RAID 1 capacity?
Turn on the system and boot into Windows. Open the Intel Rapid Storage Technology user interface and click the Create icon. Follow the prompts to create a new RAID 1 volume. Your data will then be migrated from the single large drive to the new RAID 1 volume.
What is the maximum number of drives for RAID 1?
Raid level 1(RAID 1)\n\n Maximum number of drives in RAID 1 can be 32, from a starting number of 2(even number of disks are required.)
Can RAID 1 have 4 drives?
RAID 1 consists of at least two drives, so four drives are acceptable. The data distribution mechanism here is mirroring. This type of array has excellent performance, where the write and read speed is high. However, you can only use 50 percent of independent disks for data storage.
