Do the new SATA hard drives have slave and master settings?

-No. The boot order for SATA drives is set from the BIOS.



SATA drives do have some jumper settings but these rarely need to be changed from the default



SSC - Spread Spectrum Clocking is a way to lower electromagnetic interference (EMI) or electronic noise. Mainly used to pass FCC emssions standards in multi-drive computers.



PUIS - Power-up in standby - prevents the drive from automatic spinup when power is applied, drive gets to full speed only when used. It's a power conservancy measure. Your motherboard has to support this else the drive might not start properly at all.



1.5Gb PHY - forces a drive into 1.5Gbps transfer mode rather than 3.0Gbps mode. The PHY stands for physical layer, a reference to layer 1 of the OSI (Open Systems Interconnection) model.No. The boot order for SATA drives is set from the BIOS.
