You certainly do not want another transaction to hinder you by reaching a higher level.If there is no intent lock, then the higher-level object will not know that there is a lock on the lower level. Intent locks improve performance because SQL Server only needs to

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
