SATA 3 is supported but lapotp only uses SATA 2

[computernoob12344]

Please help me! My laptop (Samsung NP370R4E-S07PH) says it can support SATA 3. Speccy and others says my hard drive (Seagate ST500LT012-1DG142) is only using SATA 2 but the hard drive is also SATA 3. I'm planning to upgrade my laptop to an SSD, will SATA 3 work?

Thanks!

Hello... YES... SATA3 connects and communicates with SATA2.

Hard drives don't need the speed of SATA2. Maybe the drive just runs in SATA2 mode because whatever, there's no difference anyway. It may even save a little bit of power (I know PCIe devices will step down to slower revisions that way to save power, maybe SATA can as well).
