W Write-protection state. For disk drives, a W in this

other kinds of devices.
C Caching state of the device:
a = read, write-back, and read-ahead caching enabled
b = read and write-back caching enabled

KB/S Average amount of data transferred to and from the unit
during the last update interval in 1000-byte increments.
Rd% Percentage of data transferred between the host and the
unit that were read from the unit.
Wr% Percentage of data transferred between the host and the
unit that were written to the unit.
CM% Percentage of data transferred between the host and the
unit that were compared. A compare operation can
accompany a read or a write operation, so this column is
not the sum of columns Rd% and Wr%.
