Bigger drive always best for OS?

[ExoMale]

i know you need a decent size hdd to acompany the operating system plus all updates, but I have 2 hard drives spare than I'm going to use on a computer I'm rebuilding to sell and the choice I have is a 500gb 3gb/s and a 1TB 6gb/s with which I was going to put the os(64 bit 7 or 8.1) on the 500gb and use the bigger drive for storage, the board I'm using supports both speeds, so no compromises needed there.

Mean I don't even need to use both drives, I just don't need both in general so was going to hope it adds appeal lol, but I have always put the os on the smaller drive in a 2 drive setup unless the smaller one was purchased as the secondary, had no problems myself, but have had advice that I should put the os on the bigger drive before, Suppose when it comes to selling or building for someone I favour quantity over performance.

Thanks for the reply, sadly not really an option unless I can get the funds from somewhere, but performance aside it was more to do with if it's always better to put the os on a bigger drive for the fact of the extra space as I find 500gb pretty quick compared to anything under 250gb anyways and obviously 1tb even quicker.

Thanks for the replies guys, I will have a look at current prices of 2nd hand ssd's, The computer is already up and running and ready for sale, I chose the 1tb hdd only option as Windows could be reset to factory so I didn't need to use the key as it was automatic, so it was easier, but I've been away for the weekend, so didn't get to advertise anyways, so still got possible options.
