you'll never hit 3Gb/s. 65 80MB/s is typical for a mechanical hard drive. AHCI gives you other features but does not greatly affect transfer speeds of traditional hard drives. AHCI is a bigger deal with SSDs.
between drives is around 65 80MB a second, which isn't what SATA 3Gbit is capable of. I know I won't hit 3Gbit all the time but I should be pulling at least 120 180MBPS
I spoke to someone more knowledgeable with motherboard, apparently the nVidia chipset on this board had issues with AHCI mode, so it is automatically disabled. Which gives me the perfect excuse to buy a new board.
Being I steam video to my flatscreen I also use it as a file server for the rest of the house.
I have a Emachines ET1352g. I have upgraded it to a Phenom x3 703e, 8 GB DDR3, upped the PSU Antec TP 650, new heat sink and fan and a new VisionTek AMD HD 5670 GPU, I have 6 TB of HD Space.
In the BIOS where I can select between AHCI Dunhill Belt Buckle and IDE mode for the HD's it is only allowing me to use the IDE mode instead of the AHCI mode. The option says IDE mode Michael Kors Belt White
and it is grayed out.
Got a question that has had me banging my head against the wall.
