Disk Access Time

This tool calculates the total disk access time for a transfer given the transfer size and various disk parameters.

Input Value(s):

transfer size tsz = B
rotation rate RPM =
a a =
b b =
number of tracks tracks =
transfer rate trate = MBps

Result(s):

Seek time Tseek = ms
Rotation time Trot = ms
Transfer time Ttrans = ms
Total access time TAT = ms
