1.1 About the Serial ATA interface The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary advantages include: � Easy installation and configuration with true plug-and-play connectivity. It is not normally necessary to set any jumpers or other configuration options. � Thinner and more flexible cabling for improved enclosure airflow and ease of installation. � Scalability to higher performance levels. In addition, Serial ATA makes the tran

Provide power savings and battery life NVC decreases power consumption by reducing the amount of time the discs are spinning in the HDA. Improve reliability Shock and vibration impacts during writes is negligible when writing to NVC memory. This results in an overall Annualized Failure Rate (AFR) of less than 0.50%. Reduced acoustics Reads and writes from NVC memory may occur without the acoustic impact of spinning media and actuator movement. Momentus 5400.3 PSD SATA Product Manual, Rev. A 3

2.0 Drive specifications Unless otherwise noted, all specifications are measured under ambient conditions, at 25°C, and nominal power. For convenience, the phrases the drive and this drive are used throughout this manual to refer to the various models. 2.1 Specification summary table The specifications listed in this table are for quick reference. For details on specification measurement or defi- nition, see the appropriate section of this manual. Table 1: Drive specifications summary Dri

**During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels. ***Typical notebooks will pull power to the drive when entering S3 and S4; while in the S3 and S4 states, drive sleep and drive standby modes will not contribute to battery power consumption. 2.2 Formatted capacity Model Formatted capacity* Guaranteed sectors Bytes per sector ST91608220AS 160 Gbytes 312,581,808 512 ST9120822

2.7 Seek time Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications in the table below are defined as follows: � Track-to-track seek time is an average of all possible single-track seeks in both directions. � Average seek time is a true statistical random average of at least 5,000 measurements of seeks between random tracks, less overhead.

2.9 Power specifications The drive receives DC power (+5V) through a native SATA power connector. 2.9.1 Power consumption Power requirements for the drives are listed in the table on page 10. Typical power measurements are based on an average of drives tested, under nominal conditions, at 25°C ambient temperature. • Spinup power Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed. � Seek mode During seek mode, the read/write actuator arm
