On which hard drive would windows perform the best?

I’m upgrading from a 32bit Win 7 OS to a 64bit Win 7 OS. I have 4 hard drives (None of which are a SSD) and was curious if dedicating one of my smaller drives exclusive to OS would be more efficient for faster data transfer or if I’d be better off using a larger one due to larger cache. Honestly don't know much about this subject so any feedback or information would be appreciated.

Here are my drives:

Hitachi 2TB 7200 RPM 32MB Cache SATA 3.0Gb/s

Western Digital 1TB 64MB Cache SATA 6.0Gb/s (Could not find RPM specifications)

Western Digital 250GB 7200 RPM 8MB Cache SATA 3.0Gb/s

  1. Installing your OS on the 1 TB Western Digital drive will work the best, since it has a 64 MB Cache.
  2. The 1TB WD drive, as long as its not a WD Green.

    I believe it is in fact a WD Green. "Reduced power consumption " and "Eco-conscious design"

    How will that impact performance?
  4. WD Green run at 5400 RPM.

    Don't use a WD Green for the boot drive. In an attempt to be 'green' and 'eco friendly' it spins down and up according to its own internal brain.
    Overall performance will suffer.

    And the Green thing is mostly BS. You might save a dollar or two per year.
  6. So is the consensus to use the 2TB because of the higher RPM and Cache size?
    I only got the WD Green because of its cheap value for larger drive capacity.
  7. Out of that group of drives, yes, I'd use the 2TB as the primary drive.
