Field Value Active UDMA Transfer Mode UDMA 5 (ATA-100) Max. UDMA Transfer Mode UDMA 6 (ATA-133) I have a single 80GB Western Digital 150mb/s SATA hard drive. Supposedly it can run at 300mb/s, but anyways, I'm using it on my asus p5b motherboard. it's run on regular ide mode where I didn't need to use a floppy to install the sata/raid drivers. My harddrive isn't even being used to it's potential. can someone tell me why?
