4.2.3Generalized performance characteristics

Minimum sector interleave	1 to 1
Data buffer transfer rate to/from disc media (one 512-byte sector):
	ST3500071FC	ST3400071FC
Minimum [3]*	33	35	MBytes/sec
Maximum [3]	66	66	MBytes/sec
Sustainable disc transfer rate:
	ST3500071FC	ST3400071FC
Minimum [3]*	32	27	MBytes/sec
Maximum [3]	67	56	MBytes/sec
Fibre Channel Interface maximum instantaneous transfer rate			1 GHz	2 GHz

106 Mbytes/sec* per port (dual port = 212 Mbytes/ sec*)

212 Mbytes/sec* per port (dual port = 424 Mbytes/sec*)

Note. 1 Megabyte (MB) = 1,000,000 bytes.

Sector Sizes
Default is 512-byte data blocks.
Logical block sizes
Default is 512-byte data blocks
512, 520, 524, and 528 supported.
Read/write consecutive sectors on a track	Yes
Flaw reallocation performance impact (for flaws reallocated at format time	Negligible
using the spare sectors per sparing zone reallocation scheme.)
Overhead time for head switch in sequential mode	1.56 msec
Overhead time for head switch in sequential mode
Overhead time for one track cylinder switch in sequential mode	0.66 msec (typical)
Average rotational latency	4.17 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.

Notes for Section 4.2.

[1]Execution time measured from receipt of the last byte of the Command Descriptor Block (CDB) to the request for a Status Byte Transfer to the Initiator (excluding connect/disconnect).

[2]Typical access times are measured under nominal conditions of temperature, voltage, and horizontal ori- entation as measured on a representative sample of drives.

[3]Assumes system ability to support the rates listed and no cable loss.

[4]Access to data = access time + latency time.
