Recently, I upgraded to a newer HDD, WD black version 1tb. When I boot up the system and the bios show Sata 1 HDD instead of Sata 3. I checked everything but just couldn't find the solution. I ran a program and found out that my transfer rate is only 80-120mb/s. What could be the problem???

Motherboard: Msi g54-870a
Sata 3 cable 6gb/s connected

SATA 1 (1.5Gb/s) speeds are from 1MB/s to 150MB/s.
SATA 2 (3Gb/s) speeds are from 151MB/s to 300MB/s.
SATA 3 (6Gb/s) speeds are from 301MB/s to 600MB/s.

Advertised speeds for the 1TB WD Black are "up to" 150MB/s.

HDDs can be SATA 3 "compatible", not SATA 3 "capable".
No HDD can spin fast enough to achieve SATA 3 speeds. Your WD Black has a 64MB cache which can transfer its contents at SATA 3 speeds, but that's it.
