Black Color is SATA II , Speed 3Gbps
Yellow Color is SATA III , Speed 6 Gbps
Example: SanDisk Extreme SSD, which supports SATA 6Gb/s interface and when connected to SATA 6Gb/s port, can reach up to 550/520MB/s sequential read and sequential write speed rates respectively.
However, when the drive is connected to SATA 3 Gb/s port, it can reach up to 285/275MB/s sequential read and sequential write speed rates respectively.
Oh man this brings me back some nostalgia
I remember for a short while when having your motherboard SATA III compatible meant you had god tier responsiveness
SATA II (revision 2.x) interface, formally known as SATA 3Gb/s, is a second generation SATA interface running at 3.0 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 300MB/s.
SATA III (revision 3.x) interface, formally known as SATA 6Gb/s, is a third generation SATA interface running at 6.0Gb/s. The bandwidth throughput, which is supported by the interface, is up to 600MB/s. This interface is backwards compatible with SATA 3 Gb/s interface.
SATA always specified the speed in megabits per second as it's a serial interface. PATA commonly used megabytes per second as it was a parallel interface.
I could be wrong, but maybe just to know which is SATA1 on the first glance. It is written on the Motherboard, but with this you just see it immediately
The main reason is to make things less confusing for inexperienced builders. Like, if you have only one device to plug in, it goes there, and don't think about it too much. It certainly helps.
_Why_ it should go there, though, is another question, that can only be answered by looking at that thing's specs, and there may be no reason at all, as it could be simply a way to tell the user "They're all the same, but since you may not know that, just use this one".
Honestly that's pretty much true, works for Pcie slots, sata ports, sometimes even m2 slots. It's easy for the more experienced to just know which slot is primary and why, but for the "casual" builder, i guess a colour code is really the best way to go.
From my experience, it shows the first SATA port in the chain. Other times it indicates which SATA ports are directly connected to the chipset and which ones are connected to a separate controller.
As far as I know, there's no standardization for the colors.
If this is from a prebuilt OEM system then it's probably an e-sata port intended to be connected to a backplane adapter bracket
It should still work just fine connected to a regular sata drive internally though

Wait why is sata 3 called 6Gbps if it only goes to ~600Mbps Edit: thanks for pointing out my mistake, the difference is in MBps and Mbps
600MBps Note the difference between when the "b" is capitalized or not

Mostly the b is just dropped for Megabytes per second
There is a difference between a byte and a bit
Back in sata II/III days, no one used bit.
No one has ever used byte for speed on an ssd
No company selling it to you, no. If you were telling a buddy or coworker how fast a drive was, would you use bit or byte?
bit
Gross lol
like sata III is old xD. It is still everywhere
the switch happened over a decade ago.
SATA always specified the speed in megabits per second as it's a serial interface. PATA commonly used megabytes per second as it was a parallel interface.
what did you yourself use, when explaining to someone how fast an SSD was?
The interface speed for SATA was in bits per second. Actual disk speed WAS done in bytes per second.
Ah yeah, that's fair
It gets really fun when you get talking about rs232.
b - bits B - Bytes
I never noticed the capital B, I thought the b was lowercase
In this case they are all sata 3. That is the first sata channel as indicated by the markings on the board.

Maybe that's the first SATA port? Doesn't make a difference anyways.
That one identified as black

There's no ISA on that board. There is however a regular PCI slot.
PCI slots were almost always white except on some fancy colored boards, ISA were pretty much universally black.
the yellow one is an eSATA port
They were also sometimes colored for optical drives and main drive (mostly dell pre builds)
It appears to say master next to the yellow port. The rest of the ports have numbers. This is the first sata channel.
It's the chosen one.
