Pins S7-S14 and P1-P4 are used in both motherboard and host cable connectors. If one of the connectors has 4 large pins inside, it is a standard SATA cable. Step 2: Check the connectors on the cable. It was concluded that doubling the native SATA speed would take too much time, too many changes would be required to the SATA standard, and would result in a much greater power consumption when compared to the existing PCI Express bus. Step 1: Use a SATA cable with 2 connection plugs. Instead of the otherwise usual approach of doubling the native speed of the SATA interface, PCI Express was selected for achieving data transfer speeds greater than 6 Gbit/s. Important: If your drive has both power connectors, do not connect both the SATA and the legacy ATA power cable to the drive at the same time. The new BGA pinout content is based on the Socket 3 Key-M definitions. The SATA Express host connector is backward compatible with the standard 3.5-inch SATA data connector, allowing up to two legacy SATA devices to connect. At the same time, the host connector provides up to two PCI Express 3.0 lanes as a pure PCI Express connection to the storage device, allowing bandwidths of up to 2 GB/s. Attach the power supply cable To supply power to the drive you may use either the SATA power connector or the legacy ATA-4-pin (Molex) power connector on the back of the drive (see image below). This proposal will allow PCIe and SATA to be delivered using a BGA package, expanding the use of the PCIe and SATA protocols in small form-factor applications.
