4.2.2 Format command execution time for 512-byte sectors (minutes)
4.2.3 General performance characteristics
ST9146802SS ST973402SS
Maximum (with verify)
104 52
Maximum (without verify)
70 35
Minimum sector interleave 1 to 1
Data buffer to/from disc media (one 512-byte logical block)* 82 to 132 MBytes/sec
Sustained transfer rate 55 to 89 Mbytes/sec
SAS Interface maximum instantaneous transfer rate 300 Mbytes/sec* per port
(dual port = 600 Mbytes/sec*)
Logical block sizes Default is 512-byte data blocks
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 Yes
Flaw reallocation performance impact (for flaws reallocated at format time using the
spare sectors per sparing zone reallocation scheme.) Negligible
Average rotational latency 3.0 msec
*Assumes no errors and no relocated logical blocks. Rate measured from the start of the first logical block transfer to or
from the host.
