HP Pavilion DV7-4290us supports SATA 3 connection?

[FábioA]

Hi. I want to change my actual Hard Disk (SATA 2) for an SSD (SATA 3), but i don't know if my notebook (Pavilion DV7-4290us) fully supports SATA 3 connections.

I've been reading the manual and it only speak about SATA 2 (3GB/s) connections, but i think that it refers to the Hard Disk manufactures, because the chipset (Mobile Intel® HM65 Express) supports SATA 3 connections.

I made some test and it says that i have a maximun bandwich of 6GB/s, so i think that the connection supports SATA 3, but i'm not sure.

Thanks for any help or comment.

Hi,

SATA 3 is backward compatible. You won't get SATA 3 speed but your machine will accept SATA 3 HDD/SSD

If it is compatible with SATA 3 , why not reach a speed 400MB/s?

Thanks for the answer.

Hi,

As mentioned above, it will only run SATA 2 speed

Hi,

Why not work as SATA 3?

Thanks for the answer.

Hi,

Beacuse its controller uses SATA 2 technology. Let's talk this way: you've got a car which can run 400Km/h but the traffic rulers put something to its engine which stops it to run at 400Km/h. What can you do ?

Hope this makes sense.

Hi,

It's possible exchange/modify this controller? Excuse my ignorance.
