write cache exists and the algorithm is normal, RAID5 is even better than raid10, although there may not be much difference (here we should assume that there is a certain size of storage, enough write cache, and there is no bottleneck in the CPU for computing and verification ).
This is because the raid check is completed in the cache. For example, for RAID 5 of four disks, you can calculate the check in the memory and write three data and one verification at the same time. Raid10 can only wr

corruption. A dual-write buffer is a special reserved area in a tablespace, and its size is enough to accommodate 100 pages in a continuous interval. When InnoDB writes pages from the buffer pool to the disk, it first refreshes these pages to the dual-write buffer, and then saves them to the real target location. Therefore, the dual-write buffer is essentially a backup of the recently written pages, which ensures the atomicity and sustainability of each write. In some cases, dual-write bufferin
