I bought a WD caviar balack 1tb SATA 3 HDD, afetr install it and install a fresh copy of win 7 there is no performance change in windows experience index, also hd tune info says that it's a sata 2 hdd. why is that for and what should i do, my mobo is ASUS M5A97 that has two SATA 3 ports on it and i enabled AHCI mode in BIOS.
Yes my HDD is a WD1002FAEX, i just download the latest HDtune and it shows my HDD is a SATA 3 so the only diffrence between my two seagate baracuda 7200.12 500 GB SATA 2 HDDs and my WD caviar black 1TB SATA 3 is the buffer size! thats it? what about SATA 3 performance improvements?
SATA 3 has not shown to yield any improvement when using HDD. The increased buffer on the WD drive also does not seem to yield a clear performance boost. Other drives (Samsung F3 as an example) perform better or certainly equal to the WD drive without these features. WD is a good drive, it is just no enhanced much by these features.
