Sector Sizes 512 byte user data blocks (default)
Variable (256 to 4096 bytes per sector) in even number of bytes per sector. If n (number of
bytes per sector) is odd, then n-1 will be used.
Synchronous Transfer Rate
From 1.25 MBytes/sec to 10.0 MBytes/sec (See section 11.5.)
Read/Write consecutive sectors on a track YES
Flaw reallocation performance impact (For flaws reallocated at format Negligible
time using the spare sectors per track reallocation scheme.)*
Flaw reallocation performance impact (For flaws reallocated at format time Negligible
using the spare sectors per cylinder reallocation scheme.)*
*Simulated
Flaw reallocation performance impact (For flaws reallocated at format 35 ms (typical)
time using the spare tracks per volume reallocation scheme.)
Overhead time for head switch (512 byte sectors) 1 ms
Overhead time for one track cylinder switch <3 ms Typical
Average rotational latency 5.54 ms
