The final specifications for SATA 3.0 have not yet been released. Based on the draft specifications, it is possible to use the same connectors for both SATA 2.0 and 3.0.
The Sata II is has a transfer speed that is two times as fast as the original Sata. The Sata has a communication speed of 1.5 Gbit/s while the Sata II is 3.0 Gbit/s.
Is to supply additional power for PCIe video cards Original answer SATA data cables. To provide additional wattage for PCIe video cards
SATA power connector is a type of power cable with which we can provide Disks power from the mother board. SATA Power cables are connected from sata point on motherboard to the drive.
Information on SATA controllers can be found on websites such as Newegg, Directron, and Memory Express. There are many listed with complete specifications listed for each.

SATA III doubles the maximum data transfer rate for previous Serial ATA storage interface specifications from 3 to 6 Gigabits per second (6 Gb/s),
It wouldn't be a SATA motherboard if you couldn't connect SATA drives to it.
EIDE's enhancements to Integrated Drive Electronics (IDE) make it possible to address a hard disk larger than 528 Mbytes.Serial Advanced Technology Attachment (SATA)SATA are usually running in IDE emulation mode ------------------------------------------------------------------------------------ EIDE is an older legacy connection that supports data transfer speeds of about 133mb/sec. It uses thicker 40-pin ribbon cables. SATA is a newer device technology that connects harddrives with a much smaller cable and supports a lot faster data transfer in the range of 150-300mb/sec. Depending on whether you have SATA-150 or 300. (fightermage)
SATA (Serial ATA) drives are normal drives that use the SATA interface when connecting to a PC. A SATA cable is used to bridge the gap between the drive and the computers motherboard and a separate cable is used to provide power to the drive.USB, in a similar way to SATA, refers to an interface. It is possible to use a USB cable to connect a SATA drive to a USB port but only if you use an appropriate SATA-USB adapter.Most, if not all, external hard-drive kits, which may be sold as 'USB hard-drives', will contain a SATA drive inside a drive caddy with a USB cable connecting it to the PC. The caddy will already have the SATA-USB adapter built into it, negating the need to go and buy one yourself.Please don't try and wedge a USB cable straight into the back of a SATA drive as it will no doubt cause damage.
SATA 3 is backwards compatible, it means you connect it the same way as SATA 1.
Ø SATA I- 1.5 Gb/sec, SATA II- 3 Gb/sec and SATA III- 6 Gb/sec
