RAID storage capacity calculation
I'm learning RAID 5. I know it provides redundacy and improve the read/write performance by data striping and parity. The data striping means spreading data (say, a file) on several disks.
But how does the parity work exactly? mirroring? So with a RAID system, the storage capacity is one half of the real hard disk size? |
