Hard Disks include SSD, HDD, and HHD. SSD uses flash memory particles for storage, HDD uses magnetic discs for storage, and hybrid hard disks (HHD: hybrid hard disk) is a hard disk that integrates the magnetic hard disk and flash memory. HDD: hard disk drive is one of the main storage media of a computer. It consists of one or more aluminum or glass-based discs. These discs are covered with magnetic materials. The vast majority of hard disks are fixed and permanently sealed and fixed in the ha

(Omit the first step to improve efficiency)Add Corr keyword separatelyMerge by column name, and delete all column names.Perform a unique step, and then delete
