To estimate latency of fseek, we should break it into two parts: software work and hardware seek time latency. Software work is implementation of ext4 filesystem (FS, in Linux this is VFS subsystem of kernel), which will generate several "random" requests (I/O operations) to the hardware block storage device. The access time or response time of a rotating drive is a measure of the time it takes before the drive can actually transfer data. The factors that control this time on a rotating drive are mostly related to the mechanical nature of the rotating disks and moving heads.
