I want to know maximum speed capacity from my harddrive.

if I use the tool, the tool say i am using 3 MB/s I/O. Is that too much already? Am I at the limit?

How maximum speed capacity from my harddrive, I can use. How do I know that I am not using too much IO

what tool is used to know that?

In linux we can use iostat

What can I use at windows?

We do not need to know how much IO we uses. 3/MB/s is not information we need. We need to know whether if we uses 3MB/s hard disk speed, for example, we want to know whether it's 50% or 100% of hard disk power.

  • What type of drive is this? SATA? SAS? SSD? Also, 3MB/s is not IO, it is disk throughput. I/O is calculated by operations per second, either reads or writes, and do not directly correspond with the disk throughput.

Well, for getting an approximate percentage, divide the manufacture declared speed by the measured one, which you have in different tests/situations(even simple reading\writing).
