Why does RAID 5 need 3 disks?
Raid 5 requires at least 3 disks. The data is spread accoss them so that if any 1 drive fails, no data will be lost.
What is the best RAID for 3 drives?
RAID 5 Arrays\n\n A RAID 5 array is built from a minimum of three disk drives, and uses data striping and parity data to provide redundancy. Parity data provides data protection, and striping improves performance. Parity data is an error-correcting redundancy that's used to re-create data if a disk drive fails.
How many drives are needed for RAID 5?
RAID 5 provides fault tolerance and increased read performance. At least three drives are required. RAID 5 can sustain the loss of a single drive. In the event of a drive failure, data from the failed drive is reconstructed from parity striped across the remaining drives.
Can RAID 5 have 4 disks?
With a RAID 5 configuration, you can connect three to 16 drives, but four is the most common number of hard drives used in this array. Even though the minimum drives for RAID 5 is three, most users opt for four drives because of speed, fault tolerance and storage capacity.
