this time, the third and fourth disks are idle. When B data is written to the third Disk in a certain band, and B data is checked in the fourth disk, in this way, both data a and data B can be read and written at the same time.
VII. Raid 6
Raid 6 adds a verification area on the basis of RAID 5, each of which has two verification areas. They use an unused verification algorithm to improve data reliability.

If you calculate this value, errors will inevitably occur. 5-1. This situation can be called data correlation between adjacent commands. For openmips, it can also be called data correlation in th

single-block mechanical disk available on the market now has only 10TB of storage space. When this part of the capacity is used to expand it is basically an impossible task to complete. Finally this storage method also has the security question, the single piece mechanical disk in the continuous high I/O environment is very easy to damage, as long as is a certain capital support company, the mechanical disk itself is regarded as the consumable.So even in a start-up company's online production e
