Hello , I am using toshiba satellite p50-a laptop . It has a hdd 1 Terabyte  hard disk. 

i want to replace it with ssd one,But i don't know which SATA mode compatibility I should buy.

The current hdd is sata 2 but I don't know if I can replace it with a sata 3 mode ssd  .So i installed sissoftware  sandra

 

it shows me when i entered the mainboard 

 

port                                                G2/sata300  (I think that this the hdd ) 

port                                                G1/sata150  (I think that this the dvd reader)

maximum sata mode                    G3/sata600 

 

knowing that sata150  is sata 1

                     sata300  is sata 2

                     sata600  is sata 3

SATA3 is backward compatible, SATA2 is backward compatible.  Your motherboard determines the max SATA speed supported.

 

"SATA II specifications provide backward compatibility to function on SATA I ports. SATA III specifications provide backward compatibility to function on SATA I and SATA II ports. However, the maximum speed of the drive will be slower due to the lower speed limitations of the port."

 

More.Info.

 

SATA3 drives are the more prevalent today.
