I have a Gigabyte GA-X58A-UD3R motherboard with 2x 1TB Western Digital WD1002FAEX SATA 6Gb/s drives (and an older SATA II drive). My PC is running Win 7 64bit. It might be just me but lets say I'm doing some intensive hard disc bashing (like copying files) - the PC becomes almost slow to use and even simple things like loading a web page takes noticeably longer. Surely thats not normal? Could it be incorrectly set up or a driver issue? Running in standard IDE mode and no Raid.
