General performance characteristics
Minimum sector interleave
Data buffer to/from disc media (one 512-byte logical block)*
Sustained transfer rate
SAS Interface maximum instantaneous transfer rate
Logical block sizes
Variable 512 to 528 bytes per sector in evenly divisible by 4 number of bytes per
sector (512, 516, 520, 524, or 528). If n (number of bytes per sector is not divisi-
ble by 4, the next lowest number that is devisible by 4 will be used.
Read/write consecutive sectors on a track
Flaw reallocation performance impact (for flaws reallocated at format time using the
spare sectors per sparing zone reallocation scheme.)
Average rotational latency
*Assumes no errors and no relocated logical blocks. Rate measured from the start of the first logical block transfer to or
from the host.
