 3 Platters = 6 surfaces. 16TB / 6 surfaces = 2.666 * 10^12 bytes. Bytes per track = 2.666 * 10^12 bytes / 2 * 10^5 = 1.333 * 10^7 bytes = 13MB

3 platters -> 6 surfaces

Number of bytes/surface = 16TB / 6 surfaces = 2.67 TB

Number of bytes/track = 2.67TB / 200,000 tracks = (2.67*10^12 B) / (2*10^5 tracks) = 13.35 MB

We have 3 platters -> 6 surfaces. We have 16TB Capacity in total. Per surface we have 8/3 TB.

We have 200,000 tracks per surface. Therefore, we have (8/3) / (200,000) TB/track Which is 13.33MB per track!
