Hard Disk sata 2,3?? WTF?

And7rey · Dec 27, 2013

So, I talked with my friend yesterday about buying a new motherboard and CPU , he said that Hard Disks have specified SATA-s , that means I can't connect a SATA 3 cable on a SATA 2 Hard Disk , and I said WTF??? I'm not sure if it's true but I wan't to make sure.

All SATA cables are the same.

Basically yes, loads of research on the internet confirming this. All SATA cables perform at the same speed but SATA connectors do not. SATA 3 is faster 6gbps but unless you are using an SSD it will make no difference. Even with an SSD the difference will be difficult to notice day-to-day. Also SATA is backwards compatible so a SATA 3 drive will work on any SATA port.

And7rey :

Agreed with the comments above. To just clarify a bit:

There is no such thing as a "SATA 3 cable". All SATA cables are identical.

There are SATA 1, SATA 2 and SATA 3 ports available on motherboards. 3 is twice as fast as 2, which in turn is twice as fast as 1. It is all backwards and forwards compatible, all SATA harddrives will work in all SATA ports regardless of speed/specification.

Example: If you plug in an SSD capable of pushing, say, 500mbps, into a SATA 2 port, the SATA 2 port is only capable of 300mbps so your SSD would simply slow down to 300mbps.

No harddrive can come remotely close to SATA 2 speeds, never mind SATA 3, SATA 2 will only be limiting with a high end SSD.

Is it same with HDD , couse I have a HDD and not SSD

Yes And7rey, if you have a HDD then don't worry about it at all. You will not have any compatability problems or speed issues.

And7rey :

As far as SATA is concerned, a HDD and an SSD are identical. The cable/port/connection is identical on a HDD and an SSD.
