2. SATA - Wikipedia

   en.wikipedia.org/wiki/SATA

   A fifteen-pin SATA power connector (This particular connector is missing the orange 3.3 V wire.) SATA specifies a different power connector than the four-pin Molex connector used on Parallel ATA (PATA) devices (and earlier small storage devices, going back to ST-506 hard disk drives and even to floppy disk drives that predated the IBM PC). It ...

3. Hard disk drive interface - Wikipedia

   en.wikipedia.org/wiki/Hard_disk_drive_interface

   The SAS is a new generation serial communication protocol for devices designed to allow for much higher speed data transfers and is compatible with SATA. SAS uses a mechanically identical data and power connector to standard 3.5-inch SATA1/SATA2 HDDs, and many server-oriented SAS RAID controllers are also capable of addressing SATA hard drives.

4. Power supply unit (computer) - Wikipedia

   en.wikipedia.org/wiki/Power_supply_unit_(computer)

   Serial ATA power connectors: a 15-pin connector for components that use SATA power plugs. This connector supplies power at three different voltages: +3.3, +5, and +12 V, in three pins per wire, one designed to precharge capacitive loads on for hot-plugging designed backplanes.

5. U.2 - Wikipedia

   en.wikipedia.org/wiki/U.2

   U.3 (SFF-TA-1001) is built on the U.2 spec and uses the same SFF-8639 connector. A single "tri-mode" (PCIe/SATA/SAS) backplane receptacle can handle all three types of connections; the controller automatically detects the type of connection used. This is unlike U.2, where users need to use separate controllers for SATA/SAS and NVMe.

6. Molex connector - Wikipedia

   en.wikipedia.org/wiki/Molex_connector

   As SATA becomes more prevalent, Molex connectors can be found repurposed, through use of an adaptor, to serve as six-pin PCIe power connectors to make up for a lack of such connectors on a power supply. Lower power devices (e.g. 3.5-inch floppy drives) use the smaller AMP 171822-4 connector instead.

7. Parallel ATA - Wikipedia

   en.wikipedia.org/wiki/Parallel_ATA

   The ATA connector specification does not include pins for supplying power to a CF device, so power is inserted into the connector from a separate source. The exception to this is when the CF device is connected to a 44-pin ATA bus designed for 2.5-inch hard disk drives, commonly found in notebook computers, as this bus implementation must ...

8. eSATAp - Wikipedia

   en.wikipedia.org/wiki/ESATAp

   A version of this wide connector is found inside every external SATA hard drive enclosure; when the hard drive is slid inside, it mates with a connector that supplies it with both signal and power. If the smaller side of this cable is plugged into a "powered" ESATA port, providing both 12 V and 5 V, then the wide end may be plugged into a 2.5 ...

9. Spin-up - Wikipedia

   en.wikipedia.org/wiki/Spin-up

   In SATA 2.5 and above, the drive starts without spinup if the "disabled stagged spinup" (DSS) pin (standard power connector pin 11) is left floating. It only spins up when spoken to (physical layer initialization). [4] On connectors designed around older SATA revisions, the pin is connected to ground, disabling the feature.
