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 time using the spare sectors per track reallocation scheme.) [10] Negligible Flaw reallocation performance impact (For flaws reallocated at format time using the spare sectors per cylinder reallocation scheme.)
