DISK I/O: it display what percentage of time a disk in use by a read or write command.
TiB(Tebibyte) : 1 Tib = 1.10 TB = 1024 Gibibytes , 1 Terabyte = 1000 Gigabytes
GiB(Gibibyte) : 1 Gib = 1.07 GB = 1024 Mebibytes , 1 Gigabyte = 1000 Megabyte
Mib(Mebibyte) : 1 MiB = 1.05 MB = 1024 Kibibytes , 1 Megabyte = 1000 Kilobyte
