Swap partition
A swap partition is used for memory management. If you’re running many applications and you’re running out of memory, your OS can temporarily copy unused information to the storage device in the swap partition. When the information is needed again, the information is loaded back to RAM. A swap partition is usually a fast drive or SSD.
Quick format vs. full format
A format initializes the file system. A quick format creates a new file table. It doesn’t erase any data that already existed on the drive. It also doesn’t do a physical check to make sure everything is in good working order on the drive.
On Windows 7, 8/8.1, and 10 a quick format is the default format that occurs in the operating system installation program.
To perform a full format, you’ll need to run the diskpart command.
A full format takes longer. It writes zeros to the whole disk and your data is unrecoverable. A full format also checks the disk for bad sectors.
