Maybe a bit odd question ...but what _exectly_ is Read_Time/Write_Time in disk's NCPA API...

unit says: ms

Is it write time of single IO? Is it some standarized IO, average IO size from x samples?
Time in ms spend during 1 sec for read/write? so in fact % of write/read time spend by disk?

Eg. disk's "Write_time was 1084.47 ms/s"

it's a bit confusing to see 1000+ ms in one second.
