Interleave factor
Interleave factor -
a number of sectors which pass under a read/write head while the hard drive processes the sector it just read, before it starts dealing with the next sector.
Sectors on a track are arranged in a specific pattern so that as the processing of the sector is complete,
the next sector is just arriving under a head.
Proper interleaving significantly reduces rotational latency.
Interleaving is not used in modern hard drives because processing speed increased significantly.
Internal drive
Internal drive -
a device to store data, connected to a computer motherboard directly.
