When we talking about the RAID (RedundantArray of Independent Disks), when learning about the RAID level 2 there was party called Hamming-party. What is mean by the Hamming-party and how it will help to make disk spindle rotation is synchronized?

Hamming code in Redundant Array of Independent Disks

RAID2 stripes data at the bit level. Richard Hamming develop Hamming Code for error correction. The Disks are Synchronized by the controller to spin at the same angular orientation. Means they reach index at the same time. Due to this, Extremely high data transfer rates are possible.

Using Hamming Code errors are corrected. It Consists of four data bits and three parity bits. It also permits 7 disks, four are used for data storage and three are used for error correction. Other RAIDs can detect single-bit corruption in data but can not resolve contradictions between parity bit and data bit without human interaction. In RAID2, data is strongly protected from corruption. Hamming Code Algorithm is used to check bytes for errors and also it is responsible to allow drive controller to rebuild data in its original form.

Finally, RAID2 is now the part of computing technology.
