SATA enhancements move the data transfer speed to 300MBps, and

The Serial ATA interface is the serial version of the IDE These pin outsįor the Serial ATA connector are not compatible with the legacy PATA SATA signal names are with respect to the Host, the device connected to Here is a chart of Hard Drive Transfer Speeds. The SATA interface is muchįaster then the PATA interface, but depending on the disk platter speed,Ī transfer increase may not be seen. Place your main Diskĭrives on the Serial ATA interface if possible and the older drives on Interface to handle older Hard Disk Drives. Some motherboard's also have the Legacy PATA
To date all new mother board designs are shipping with one or more SATA PATA Power pinout IDE Power Connector Pin Out Pin # SATA Power pinout SATA PinOut, Power Pin # The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37 inches). The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connections. The PATA interface is not visible in the diagram. Power cable to supply a connection which is more rugged and reliable then the The PATA power connector may be used in instead of the SATA Hard drive may also have a third connector for legacy PATA power One connector for the data lines and one for the power lines. The Serial ATA bus is defined over two separate connectors, It was known that there could be legacy compatibility issues.Serial ATA Signal Assignments SATA Cabling Diagram At that time, the STA (SCSI Trade Association) researched the marketplace and determined that there were no conflicting legacy concerns. Q: When was this feature introduced on SAS HDDs?Ī: With the introduction of 12G SAS, a new SAS standard, SAS-3, redefined P3 (Pin 3) from “3.3V Power” to “POWER DISABLE”, i.e. The issue as the HGST document explains is that P3 (Pin 3) functionality was re-defined for SAS spec, and then later it was pushed into SATA Rev 3.3. The problem can usually beĮliminated by using a simple “Molex to SATA” power adaptor to supply Power Disable feature to get stuck in a hard reset condition Supplies that provide 3.3 V power on Pin 3 would force drives with The new Power Disable feature (similar to the SAS Power Disableįeature) uses Pin 3 of the SATA power connector.
However, very few drives actually use it, so they may be powered fromĪ four-pin Molex connector with an adapter. I'd like to rule out MOLEX factor.ģ.3 V is supplied along with the traditional 5 V and 12 V supplies. I've connected one SATA harddrive with Molex-SATA adapter I see errors at Linux boot time. I'm trying different connections of power peripherals. Should a drive have 3.3V specs written on its front along with 5V and 12V if it uses 3.3V? (I don't recall seeing 3.3V specs on harddrives myself, but maybe my drives are not that modern).Am I correct in understanding that no SATA hardrive needs 3.3V for "basic" (identification/read/write) operations?.
