SATA

SATA I - 1.5 Gbps
SATA II - 3 Gbps
SATA III - 6 Gbps (2009)

SATA 6, also known as SATA 6.0 or SATA III-600,
- a newer version (of sata III)
- released in 2013
- provides a maximum data transfer speed of 12 Gbps.
- Both SATA 3 and SATA 6 SSDs use the same SATA interface to connect to a computer’s motherboard.
- SATA 6 SSDs are backward compatible with SATA 3 motherboards but will then operate at SATA 3 speeds.
to get the full speed, the complete IO system must all support SATA-6

SATA 3.x versions

PWDIS issue with sata 3.2 & higher and older interfaces

pin 3 was not in use , but is now used to signal power disable
result : HD will never spin up , because it receives shut down signal constantly

The first solution involves a piece of Kapton tape to cover that third pin.

It’s a special type of non-conductive tape that’s stable at both low and high temperatures, and is yellowish in color. Take a piece of backing paper from a sheet of labels and place the tape onto it. Then take a piece of cardboard and place it underneath. The goal here is to cut a thin strip of tape - enough to cover that third pin - so take a razor and gently slice off a strip of tape. Next, on the hard drive, locate the third pin, and gently apply the tape. I highly recommend that you use an ESD wrist strap while you’re doing this, as you are touching the contacts of the drive. The tape is too long for the pin, so snip off the excess with some scissors.

Going back to the computer, while the Kapton tape is on the third pin, connect the power cable which will slip right over the tape, and then the data cable. After booting up the PC and returning to the storage information in the BIOS, we can see that the Western Digital drive is indeed being recognized - and if you boot into Windows or whichever operating system you’re using, you will see the drive and be able to partition it and format it.

The second solution involves a Molex-to-SATA power adapter, which goes between the hard drive and the power supply. The one shown here has both a power adapter and a data connector, so it’s a two-in-one adapter, but all you really need is the power piece of it. They sell just the Molex-to-SATA adapter, separate from the data cable. All you need to do is connect the adapter to a molex connector coming from your power supply, and the other end to the hard disk. These adapters effectively bypass pin 3 on the SATA power connector. Please note that some cheaply made adapters have been known to catch fire, so please do some research and purchase a high quality adapter.
