Default ATA-100

I heared that rate of transmission of files in HDD with ATA-100 is 100
MB/s but I tried this and measured its speed about 4 MB/s. Which is
correct and why?

Transfer over the bus interface is 100MB/s. You were probably
reading small blocks, and incurring a rotational delay on each
block. Or maybe doing real short stroke random.

That said, when you do get the data streaming off the disk, it
still may not be coming off as fast as the bus can take it.
