I have an ASUS M3A mainboard with two 750 GB hard drives. Both are nearly\nfull so I'd like to add a third, larger hard drive, probably a 3 TB drive\nsince they have become fairly affordable at 0 for an internal one.\n\nAre there any negatives associated with adding a third drive to this\ncomputer, especially one that is larger than the others? Is there any reason\nwhy it would be better to make the new drive external than internal?\n\nAlso, would I put the third drive on the same 80 conductor ribbon cable as\nthe existing two drives - I haven't had the case open in a while and can't\nremember if there is a third connector on the cable - or would I need to run\na second ribbon cable from the motherboard? Is it even possible to have a\nsecond ribbon cable from the motherboard? I am very weak on matters of\nhardware so forgive my question, which may be very foolish.\n\nThe main thing I'm storing on these drives is large standalone data files if\nthat makes any difference.\n\nI'm running Windows XP with no immediate plans to upgrade to Win7.
