Can I do RAID 5 with 3 drives?
RAID 5 requires a minimum of 3 drives, and will recover data if one drive fails, but compared to RAID 1, RAID 5 offers greater write performance.
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.
How many disks does RAID 5 require?
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.
What RAID can I use with 3 disks?
A RAID 5 array is built from a minimum of three disk drives, and uses data striping and parity data to provide redundancy.
