The reasons of using SATA 3.0Gbps?

I bought Lenovo Y510p which is basically considered as gaming laptop in some reason(the community said).

I take a look about the HDD installed it, which is 1TB 5400 RPM SATA HDD.

Somebody said 5400RPM HDD is for more stable data read/write(maybe?), so I searched the model for more info of my HDD installed in Y510p.

Model: STL1000LM024-HN-M101MBB (From device manager)

Googled it and found this: http://www.newegg.ca/Product/Product.aspx?Item=N82E16822152291

It says the HDD is running on SATA 3.0gbps. I know there's a faster SATA 6.0gbps. So, this is a gaming laptop but why Lenovo don't put a SATA 6.0gbps in it? Or is Lenovo considered the pricetag so don't use SATA 6.0gbps HDD?

USAFRet is right - SATA 6.0 Gb/s HDD's cannot perform any faster than SATA 3.o Gb/s. About the 5400 rpm - MANY HDD's in laptops run at this speed because it uses less power and generates less heat. Many also are designed to spin down when not in use, then start up again when needed, and this saves battery power. It has nothing to do with "stability".

1. The words 'gaming laptop' are pure marketing.

2. A standard HDD, be it 5400 or 7200 RPM, can't fill a SATA II interface. So it make no sense to designate a SATA III HDD.

3. Whoever told you that 5400 was 'more stable' is just repeating crap they heard.
