2.2 Formatted capacity Model ST3320410SV Formatted capacity* 320 Gbytes Guaranteed sectors 625,142,448 Bytes per sector 512 *One Gbyte equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting. 2.2.1 LBA mode When addressing the drive in LBA mode, all blocks (sectors) are consecutively numbered from 0 to n-1, where n is the number of guaranteed sectors as defined above. See Section 4.3.1, "Identify Device command" (words 60-61 and 100-103) for additional information about 48bit addressing support of drives with capacities over 137 Gbytes. 2.3 Default logical geometry Cylinders 16,383 Read/write heads 16 Sectors per track 63 LBA mode When addressing the drive in LBA mode, all blocks (sectors) are consecutively numbered from 0 to n-1, where n is the number of guaranteed sectors as defined above. 2.4 Recording and interface technology Interface Recording method Recording density (kbits/inch max) Track density (ktracks/inch avg) Areal density (Gbits/inch2 avg) Internal data transfer rate (Mbits/sec max) Sustained data transfer rate (Mbytes/sec max) I/O data-transfer rate (Mbytes/sec max) 320 GB models Serial ATA (SATA) Perpendicular 1,242 kbits/in max 173 ktracks/in avg 215 Gbits/in2 avg 1,201 Mbits/sec max 90 300 6 SV35.4 Series SATA Product Manual, Rev.
