Read/write consecutive sectors on a track Yes
Flaw reallocation performance impact (for flaws reallocated at format time,
all P and G list entries will be slipped). No performance hit
Overhead time for head switch (512 byte sectors) in sequential mode 2.5 msec (typical)
Overhead time for one track cylinder seek (cylinder skew) <3.5 msec (typical)
Average rotational latency 4.17 msec
