Data Buffer To/From Disc Media
Data Transfer Rate (< 1 Track) - 512 Byte Sector
Min. [4] 2.88 MByte/sec divided by (Interleave Factor)
Avg. [4] 3.94 MByte/sec divided by (Interleave Factor)
Max. [4] 4.6 MByte/sec divided by (Interleave Factor)

Transfer Rate (Asynchronous) [5]
-Maximum Instantaneous
-Maximum Average
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
Flaw reallocation performance impact (For flaws reallocated at format
time using the spare sectors per track reallocation scheme.)*
Flaw reallocation performance impact (For flaws reallocated at format time
using the spare sectors per cylinder reallocation scheme.)*
*Simulated
Flaw reallocation performance impact (For flaws reallocated at format
time using the spare tracks per volume reallocation scheme.)
Overhead time for head switch (512 byte sectors)
Overhead time for one track cylinder switch
Average rotational latency
